Cruachan 2 is set to be built within a new, hollowed-out cavern which would be large enough to fit Big Ben on its side, to the east of Drax’s existing 440 megawatt (MW) pumped storage hydro station. The project will bring an additional 600 MW of power – increasing the site’s total capacity to over 1 gigawatt (GW). The new plant could be operational as soon as 2030, with almost 900 jobs created and supported during construction both directly and indirectly across the supply chain.

Drawing upon its local expertise in Scotland as well as its UK-wide proficiency, COWI will play an important role in providing technical advice for the geotechnical, jetty / marine structures and tunnelling elements of the project. COWI’s involvement in the project will also extend beyond the power station to the wider Cruachan area by tapping into its extensive experience in rail to support considerations made for the railway line beneath which the new access and tailrace tunnels will run.

Cruachan 2 will help support the UK goal of 30 GW of energy storage by 2030. As the UK integrates more renewable energy sources into the grid, storage facilities like this will be vital for balancing supply and demand and providing key services to stabilise the Grid.

Andy Sloan, Managing Director at COWI UK comments: “We are delighted to have been selected to support Drax with this project. Scotland is undergoing a hydro-pumped storage renaissance. There’s a profound opportunity for hydroelectric developments in the UK, particularly in Scotland, which will not only address our need for long-term storage in the UK energy market but support our journey to net-zero by 2045.”

Steve Marshall, Drax’s Development Manager, said: “Pumped storage hydro plants play a critical role in stabilising the electricity system, helping to balance supply and demand through storing excess power from the national grid. When Scotland’s wind turbines are generating more power than we need, Cruachan steps in to store the renewable electricity so it doesn’t go to waste. With the right support from the UK Government, Drax is ready to invest around £500m to more than double Cruachan’s generating capacity and support almost 900 jobs across the supply chain during construction.”

Spanning a period of six years, a comprehensive construction program is expected to start in 2025 with ambitions to complete the project by 2030.

The Effect of Slips, Trips, and Falls

Slips, trips, and falls might sound like everyday occurrences, but within the rail industry, they can trigger a chain reaction of problems.  Whether it’s a passenger slipping on a platform, a staff member tripping on uneven flooring, or a contractor falling while maintaining equipment, the consequences can be severe.

Human Toll

Slips, trips, and falls can lead to injuries ranging from minor sprains to more serious fractures or head injuries. Each incident not only affects the individual involved but also their colleagues, family, and the overall morale of the workforce.

Operational Disruptions

Even a brief halt in rail operations can have a cascading effect on schedules and customer satisfaction. If a worker or member of the public is injured, investigations and medical attention can disrupt regular activities.

Financial Impact

In addition to potential compensation costs, slips, trips, and falls can result in legal liabilities, increased insurance premiums, and potential compensation claims. These financial repercussions can strain resources that would be better utilised for other safety improvements.

Public Perception

Safety incidents reflect poorly on the rail industry’s reputation. A high-profile slip or fall can erode public trust and deter potential passengers from choosing rail as their mode of transport.

To address the issue effectively, it’s essential to understand the risk factors that contribute to slips, trips, and falls in the rail environment:

• Weather Conditions: Rain, snow, ice, and even leaves on the tracks can create slippery surfaces, increasing the chances of accidents.
• Platform Design: Poorly maintained platforms, uneven flooring, and inadequate lighting can create hazards for both passengers and staff.
• Maintenance Areas: Work areas, maintenance pits, and equipment can become slippery due to oil, grease, and other substances.
• Human Factors: Fatigue, improper footwear, and distractions can heighten the risk of slips, trips, and falls.

How can SOCOTEC UK help?

As a leading provider of testing, inspection, and certification services, SOCOTEC UK is dedicated to enhancing safety across various industries, including rail. Our expertise can make a significant impact on reducing slips, trips, and falls within the rail sector:

The six projects include:

• New storm water storage at Pudsey Smalewell, Pudsey beginning in October 2023
• Additional storm water storage off Dick Lane, Thornbury, Bradford beginning in January 2024
• New storm water storage at Farnley ring road beginning in January 2024
• Installation of storm water storage at Kent Road, Littlemoor Bottom, Pudsey beginning in February 2024
• Installation of storm water storage at Dale Farm, Drighlington beginning in February 2024
• The creation of a 4.7-hectare integrated constructed wetland at a disused Yorkshire Water site previously earmarked for housing at Hough Side, Pudsey beginning in July 2024

Approximately 18,250m³ of additional storage will be added to the network to slow the flow of heavy or prolonged rainfall, which modelling indicates will reduce the number of storm discharges into Pudsey Beck by more than 20%.

The new integrated constructed wetland at Hough Side will accommodate a minimum 25,000m³ of diluted wastewater from heavy or prolonged rainfall events and will take approximately three years to construct. Plants in a series of cells will treat the diluted wastewater as it travels through the wetland via gravity. Pollutants and nutrients will be naturally broken down and taken up by the plants and bacteria within the wetland. The wastewater will not include solid waste.

Once established, the wetland will also provide a biodiversity net gain and improve the area for local wildlife.

Richard Stuart, director of capital delivery at Yorkshire Water, said: “We are committed to improving water quality in the rivers across our region. One of the key focuses is reducing storm overflows to make a real difference to water quality in our rivers.

“This project is a significant investment in the west Leeds and Bradford areas to improve water quality within Pudsey Beck. The additional storage and wetland we are building into the network will reduce the number of storm overflows significantly into the watercourse and is just part of a £568m capital investment we are making across Yorkshire this year alone.

“While work is being conducted in the area, there may be some traffic disruption and we are working closely with local authority highways departments to ensure disruption is kept to a minimum.

“We know that there is more to be done to tackle storm overflows. We are already working on our largest ever environmental investment as part of our 2025-2030 business plan. The plans, which will be subject to approval by our regulator Ofwat, outline a £1 billion investment to further reduce discharges from overflows to meet the government’s storm overflow reduction plan, including the requirement for coastal bathing waters of an average of two spills per bathing water season by 2035.” The project is a collaboration between Yorkshire Water, Stantec, Kier, Arup, WSP, Mott MacDonald Bentley, Peter Duffy Limited, Galliford Try, Barhale, Tilbury Douglas, Leeds City Council and Bradford Metropolitan District Council.

HS2 is asking for members of the public, living in Ealing, Brent and beyond, to help us chose names for the next two tunnel boring machines (TBMs) that will dig HS2 tunnels under the capital.

In early 2024, HS2 will launch the two machines that will construct the Northolt Tunnel East travelling through Brent and Ealing. The TBMs will set off towards Greenpark Way in Greenford, travelling 3.4miles from HS2’s Victoria Road site, near to new Old Oak Common station.

Before the TBMs set off, they are given names. As per convention, they will be named after influential women and HS2 is asking the public to vote for two names from a shortlist of five with connections to Ealing. TBM naming helps communities remember and celebrate great local woman from all walks of life.

The names on the shortlist are:

• Amy Barbour-James (1906 -1988) – Amy was born in Acton to Guyanese parents and was active in the civil rights movement. She was involved in the African Progress Unionand the League of Coloured Peoples, becoming secretary of the latter in 1942.
• Lady Anne Byron (1792 – 1860) – Lady Byron was an educational reformer and philanthropist. In 1834 she established the Ealing Grove School – the first school for the working classes, in an era when education was mainly for the wealthy.
• Brigid Brophy (1929 – 1995) – Ealing born Brigid was a British writer and campaigner whose work focused on social reform, homosexual parity, animal rights and humanism. She helped establish the Public Lending Right, allowing authors to claim a payment every time their book was borrowed from a public library.
• Emily Sophia Taylor (1872 – 1956) – Emily was a midwife, providing services for women who could not afford care, and became Ealing’s first female mayor in 1938. She was an active member of the Education Committee and the Child Welfare Committee and helped establish the Perivale Maternity Hospital in 1937.
• Susan Mary Smee (1859 – 1949) – Susan became Acton’s first female mayor in 1924, the first Justice of Peace and the first curator of Gunnersbury Park Museum. She is described as a pioneer who helped other women to follow her example.

The selected names will be displayed on the side of the TBMs which are to be lowered into a shaft ready to tunnel in the Autumn. Before launch, there will be a ceremony to bless the TBMs featuring a statue of St Barabara, the patron saint of tunnelling, conducted by a local priest.

Speaking about the naming, HS2’s Head of Community Engagement, Maddelyn Sutton, said:

“As HS2 construction begins to reach its peak, we are preparing to launch our next duo of tunnel boring machines in London. Giving the TBMs names with local connections is a great way for us to celebrate the achievements of women and for the local community to get involved in this once in a generation infrastructure project.”  

Both TBMs are170 metres long and over 1,700 tonnes in weight. They will be operated by HS2’s main works civils contractor building the London Tunnels, Skanska Costain STRABAG Joint Venture.

The tunnel they are building will be 8.4miles in total, stretching from Old Oak Common station to West Ruislip. The other 5miles of the tunnel is under construction with two further TBMs, Sushila and Caroline, already one mile into their journey.

More information on HS2’s TBM naming can be found here and more information can be found on HS2 at https://www.hs2.org.uk/. The voting is open from Monday 21^st August until Monday 4^th September 2023.

HS2 has completed the first of 32 giant piers for the first Water Orton Viaduct as work ramps up to build the Delta Junction, the project’s most complex network of structures in the West Midlands.

HS2’s main works contractor for the West Midlands, Balfour Beatty VINCI (BBV) is building the 1,400 metre long northbound and southbound structures, which will connect HS2’s Birmingham Curzon Street Station with Crewe and Manchester.

They are part of the Delta Junction, which is a triangular section of the high-speed railway made up of 9 precast segmental viaducts, embankments, and other bridging structures, with around 10km of track crossing a network of motorways, roads and rivers.

Reaching 20 metres tall at its highest point, the two Water Orton Viaducts will be amongst the tallest structures along the HS2 route, taking trains over key transport corridors including the M42, the Birmingham to Peterborough rail line and the River Tame.

The pier was built in situ with a bespoke formwork designed specifically for the project, and with a fully prefabricated reinforcement cage, assembled in the rebar factory located near Coleshill.

The piers will support the deck, which will be built using an innovative construction method and bespoke machinery. The deck segments will be produced at HS2’s nearby outdoor purpose-built Kingsbury factory near Lea Marston. The factory is making a total of 2,742 segments for the entire Delta Junction, generating over 6km of post tensioned viaduct. The segments will be transported to site using haul roads to reduce HS2’s impacts on local roads.

To reduce environmental impacts, HS2’s engineers have incorporated Ground Granulated Blast-furnace Slag (GGBS) – a by-product of the steel manufacturing industry – into the structures as an eco-friendly concrete alternative to a traditional concrete mix, reducing carbon use by more than 60%. 

HS2 Senior Project Manager for Delta Junction, Sam Hinkley said:

“This is another key moment for HS2 in the West Midlands as work ramps up on one of the most complex sections of the whole route. The Delta Junction is HS2’s key interchange where the new zero-carbon high speed railway will connect between London, the Midlands and the North.

“Minimising disruption to local communities in this area has been a key consideration in our planning, including the use of innovative pre-cast construction techniques, and haul roads to take lorries off local roads.”

After the piers are constructed, the viaduct spans will be built by raising each segment from a temporary suspension tower erected on top of each pier. When each span is complete, the suspension tower will be disassembled and moved further along the viaduct to build the next span.

An innovative ‘match-casting’ technique means that each viaduct segment is cast against the following segment in a production line, creating a seamless viaduct deck when installed. Each segment is uniquely precise and adjustable by as little as 5mm. This approach – where each segment is poured against the previous one – ensures the whole arch fits perfectly when assembled on site.

David Waite, Construction Director at Balfour Beatty VINCI said:

“Witnessing the removal of the shuttering to reveal the first completed pier for Water Orton Viaduct was an important occasion for the 1,100 people who make up the Delta workforce.

“With the production line at the Kingsbury pre-cast factory now in full swing, we will start to see the viaduct take shape over the coming months, with the first span due to be completed early next year.”

Once built, the area underneath the viaduct will be landscaped to provide a connected and accessible area with tree planting, new wildlife habitats, footpaths and cycle routes.

Over the last two years, the UK steel industry has benefitted from a pipeline of orders worth over £170m from HS2’s construction partners building the first phase of the high-speed railway linking London and the West Midlands.

As the backbone to HS2’s two-decade construction programme, over one million tonnes of steel are forecast to be needed for standard construction materials, a further 200,000 tonnes for steel rail, switches and slabtrack, and an additional 15,000 tonnes for rolling stock. 

Visiting CELSA Steel UK’s Cardiff headquarters, a UK steel provider to HS2, Ruth Todd Chief Commercial Officer at HS2 Ltd said:

“HS2’s vast demand for steel over the next 20 years, as we extend Britain’s new railway to Manchester and the East Midlands, is a lifeline for this vital UK industry and stimulates future growth potential.

“As I’ve seen here today, HS2’s supplier contracts with CELSA Steel UK are already supporting hundreds of jobs in Cardiff, Yorkshire and Nottinghamshire. Furthermore, the recyclable and retraceable products they supply aligns to our commitment to cut carbon in construction, as we strive to ensure HS2 is one of the most environmentally responsible infrastructure projects ever delivered in the UK.”

CELSA Steel UK is the UK’s largest manufacturer of steel reinforcement and a driving force behind new sustainability standards for the industry. 750 staff work at the two Cardiff-based sites where recycled scrap metal is melted in an electric arc furnace to produce 80% less carbon emissions than basic oxygen steelmaking. The molten steel is then turned in to billets and rolled to make reinforcing bar (rebar) for use on HS2 construction sites.

CELSA Steel UK transports high volumes of its materials and products by rail, not road, for the bulk of their journeys, including the scrap metal collected from its scrapyards in Cardiff, Swansea, Rotherham, Bristol and Sunderland.

Gabriella Nizam, Head of Sustainability and Strategy at CELSA UK said:

“HS2 recognise the value of CELSA Steel UK’s low carbon steel, and we’re delighted our products are supporting the construction of a railway that will deliver zero carbon journeys for millions of people.

“Our steel is produced in an Electric Arc Furnace, with 98% of our raw material being UK sourced scrap metal. Our commitment to circularity combined with our sustainable production process, establishes us as a leader in environmentally friendly steel production in the UK. While our steel is already low carbon, we are striving to reduce our scope 1 and 2 emissions by 50% by 2030 and becoming a net positive company by 2050.”

The rebar, manufactured in Cardiff, is transported to UK sites managed by British firm ROM GROUP, part of the CELSA GROUP, where it is cut, shaped, and bent to meet the bespoke requirements set by HS2’s construction partners.

Over the last two years, almost 20,000 tonnes of ROM/CELSA’s recycled British steel has helped to build HS2, and the orders keep coming. A 2,000-tonne order is a ‘big deal’ for the 100-strong team working at ROM Ltd.’s Sheffield factory, and around 140,000 tonnes of future orders are already in the pipeline from just one of HS2’s four civils construction partners.

The current scale of demand means ROM Ltd.’s Sheffield Brightside facility is almost exclusively supplying rebar for HS2. The potential to deliver a further 140,000 tonnes from the site, for just one HS2 contractor, would account for around 80% of the site’s total output over the next three years.

Brian Traynor, Managing Director of ROM GROUP said:

“HS2 brought some much needed demand for ROM GROUP during the pandemic, as the orders kept on coming.  We’ve subsequently invested over £2million in new equipment at our Sheffield facility to ensure we can maintain demand and sustain future growth.

“There’s a great sense of pride in seeing the steel our workforce has precision cut and bent being used to build the railway, and we hope that continues into the next decade and beyond as HS2 heads north.”

The boost in HS2 orders is also being felt at ROMTECH’s prefabrication facility in Sutton in Ashfield, Nottinghamshire. To date, more than 8,000 tonnes of rebar, manufactured at CELSA’s Cardiff mill, has been welded by a team of 40 specialists to create bespoke prefabricated piling cages each weighing up to ten tonnes and spanning two metre widths.

From the East Midlands factory, each piling cage is labelled and shipped to HS2 construction sites where they are used to strengthen the ground ready for the construction of bridges, viaducts, and tunnels along the route linking London and the West Midlands.

Gareth Stace, Director General of UK Steel, said:

“We are proud that UK-made steel is being used to build HS2. With the potential for two decades more orders, HS2’s investment in UK recycled steel should be emulated by many other major infrastructure projects.

“By buying UK-made steel, HS2 boosts supply chains and jobs across the country, from Wales to Yorkshire. Choosing domestic steel also means HS2 hits corporate social responsibility obligations and cuts even more carbon emissions by transporting the recycled steel by rail.

“HS2 is core to the fabric of the UK steel industry, which has around 40,000 employees and feeds into an extra 50,000 supply chain and community jobs.”

To date, over 3,000 UK-based businesses have won work on HS2 and £23 billion has been contracted into the supply chain. A workforce of nearly 30,000 are in jobs supporting HS2’s vast construction programme, and thousands more are employed in offices and factories across the UK supplying the materials, products and services needed. HS2’s construction programme is a shot in the arm for UK plc, and the Government’s commitment to extend the railway to the north provides a promising future for British industry and future job creation.

The post HS2’s demand for UK recycled steel supports hundreds of jobs while cutting carbon in construction appeared first on BDC Magazine.

The operation – which utilised the latest low-carbon design – involved excavating 14,000 tonnes of earth, building a 140 metre retaining wall and moving a 2,600 tonne bridge deck 130 metres into place under the South Staffordshire freight railway.

The work was carried out during a 10 week blockade. It was completed Balfour Beatty VINCI, and designers Mott MacDonald as part of a Design Joint Venture with SYSTRA (MMSDJV), together with teams from 18 specialist supply chain companies.

At the end of July, the 2,600 tonne bridge deck, which had been cast on land adjacent to the railway was moved 130 metres into position using self-propelled modular transporters. Since then, each side of the bridge was backfilled, the rail tracks were reinstated, with the railway line was successfully handed back to Network Rail on Wednesday 16 August and now reopened.

The 25 metres long and 18 metres wide Streethay overbridge sits within HS2’s Streethay cutting and will enable HS2 trains to travel under the existing railway between Birmingham and Crewe. Through design development, Mott MacDonald engineers were able to reduce the total length of wall structures for the railway at Streethay from 1.6 kilometres to 420 metres, meaning 80% less concrete is needed – saving around 420,000 tonnes of carbon, supporting HS2’s ambition to cut carbon on the project.

The Streethay bridge sits on top of the larger 420 metre long retaining wall structure which will have two additional bridges crossing it – the south bound A38 slip road bridge, and the Rykneld Bridge which carries the A38 north bound slip road and the A38 north and south bound carriageway.

At its peak, over 150 people worked on the complex construction operation, with teams from 18 specialist companies, delivering design, surveys, piling works, bridge build, concrete pouring, crane operations, reinforcements, modular transportation, track and systems removal and reinstatement.

The work was delivered in parallel to the construction of the nearby Fulfen Wood bridge, which involved moving a giant 6,200 tonne single span structure under the West Coast Main Line – the UK’s heaviest drive to install an intersection bridge.

David Millar, Rail Interface Manager at Balfour Beatty VINCI said: “The successful delivery of this complex and challenging piece of engineering near Lichfield is another proud moment for Balfour Beatty VINCI on the HS2 project.

“It’s only been possible thanks to the skill, dedication and support shown by the project team over the past few years, including our supply chain. Together, we’ve had to work around existing transport infrastructure, including the South Staffordshire freight railway and the A38, making this achievement even more rewarding.”

Caroline Warrington, Senior Project Manager at HS2 Ltd said: “This is a fantastic example of a project within a project at HS2, pulling together teams from 18 specialist supply chain companies from the West Midlands as well as other regions, to deliver a complex construction operation. These are some of the many companies that are helping to build Britain’s new zero carbon railway, supporting thousands of jobs right across the country.

“Unlike the Fulfen Wood bridge structure, which was constructed entirely off site, the Streethay bridge walls under the railway embankment had to be constructed during the blockade. This required a 72 day blockade, making it more of a marathon than a sprint!”

Mark Jordan, Mainline Design Director at Mott MacDonald Systra Design Joint Venture: “We’re immensely proud of the collaborative effort to get the design for this critical structure and operation ready for HS2. It’s no small task to coordinate milestones like the Streethay bridge, with expertise from our geotechnical and structural engineering teams delivering design to meet the interfacing requirements of both HS2 and Network Rail, and innovation to enable off-site construction and transportation of the 2,600 tonne structure by Self Propelled Modular Transport.”

Prior to the railway blockade, retaining walls were installed on either side of the railway, enabling the areas to be excavated. The bridge deck was constructed on land adjacent to the existing railway, 130 metres from its final position.

Once the railway was closed to freight trains, the track and embankment were removed. Bachy Soletanche Balfour Beatty Ground Engineering joint venture then installed an additional 76 secant piles measuring 1.3 metres diameter and 30 metres deep, linking to the piles they installed prior to the blockade, to create two retaining walls which act as the walls for the bridge.

A concrete capping beam was installed over the retaining walls, then the bridge was moved into place using self-propelled modular transporters with 344 wheels. Concrete was poured to attach the deck to the capping beam, the embankment was backfilled using 2,500 tonnes of structural backfill, on either side of the bridge, before the railway line was reinstated.

The next works in this area include the construction of two HS2 over bridges which will run under the A38.

The post HS2 ‘marathon’ bridge construction completed appeared first on BDC Magazine.

Working on behalf of Balfour Beatty VINCI, a team of 20 demolition experts from Solihull-based firm Armac Demolition have worked 24/7 to remove a 4,000 tonne two-span bridge over the M42 to make way for the HS2 railway in the West Midlands.

The team used eight 50 tonne excavators and two 40 tonne excavators to remove the 40 metre long, 10 metre wide bridge during a planned 56 hour closure of the motorway. Six articulated dumper trucks transported the excavated material to a local stockpile where it will be crushed and reused on HS2’s haul roads and working areas.

The whole job was completed sooner than anticipated, which meant the M42 could be reopened 14 hours ahead of schedule, shortening the closure to 42 hours and reducing disruption to road users.

Armac was working for HS2’s civils contractor Balfour Beatty VINCI to deliver the operation during the closure of the M42 near HS2’s Interchange Station construction site in Solihull.

HS2 Ltd and Balfour Beatty VINCI worked closely with National Highways and their supply chain to enable the demolition works, with all existing motorway technology diverted or removed prior to the demolition. In the last year, Balfour Beatty VINCI have also diverted power and telecommunications cables away from the structure ahead of the demolition.

The bridge, which carried the A452 over the M42, was removed to allow for a new twin box structure to be constructed, which will carry the high speed line over the motorway in the future. HS2 has built a new, improved road structure and roundabout which now carries the A452, and in future will also enable access to the new HS2 Interchange Station.

Oliver Shore, Construction Director at Balfour Beatty VINCI said: “It is through relentless collaboration with HS2 and National Highways that we have achieved this latest milestone in less than two days, overcoming technical and logistical challenges along the way.

“The demolition of the existing M42 bridge will kickstart the next phase of works, with our attention now turning to the construction of the new twin box structure which is designed to carry Britain’s new zero carbon railway – HS2 – over the motorway.”

Ian Clarke, Senior Project Manager at HS2 Ltd said: “This is another fantastic milestone for our civils team in the West Midlands, as construction of HS2 moves on at pace. The team did a brilliant job to get the demolition finished way ahead of schedule, meaning the motorway could be reopened much earlier than anticipated.”

“In this region, over 9,750 people are working on the many complex and exciting feats of engineering to build HS2 over the existing network of roads, railways, rivers and canals – creating our new zero carbon railway to connect London, the Midlands and the North.”

National Highways Senior Network Planner, Frank Bird said: “We’d like to thank motorists for their patience while the work took place and for following our diversion routes during the closure.

“This bridge demolition was a really big project and we have worked closely with HS2 over the past few months to plan the closure of the M42 and to try and limit disruption during the work.

“Given the complexity of the work involved, we’re really pleased to see the work completed ahead of time and it’s testament to the hard work of those involved that we could open the road earlier than planned.”

Noel McLean, Technical Director from Solihull-based Armac Demolition said: ‘’Armac were delighted to be working again in collaboration with our HS2 partners Balfour Beatty VINCI on the first of three major bridge demolition projects in this section. The detailed planning that had been put into the project over the last 12 months by Balfour Beatty VINCI and Armac resulted in an excellent performance over the weekend.

“A safely executed project, completed well ahead of the closure schedule, and not a single mark on the carriageway. Great performance by all involved – looking forward to the next one.”

From the full closure of the M42 at 00.25 on Saturday 12 August, a team of 30 people removed the motorway vehicle restraint system and installed protective matting. The 20-strong demolition team then moved in to remove the bridge deck, wing walls, central pier and abutments between 07.30 and 17.00 on Saturday 12 August.

The matting was removed, carriageway cleaned, and central reservation and verge restraint systems reinstated, ready for the motorway to be re-opened at 15.00 on Sunday 13 August.

Coming up next, the Balfour Beatty VINCI team will now start to construct the huge twin box structure, which will carry HS2 trains over the M42. The structure, measuring 300 metres length by 25 metres width will cover around 130 metres of the M42 and will be built in position whilst maintaining three lanes of traffic flowing on the M42.
