Steel engineering company Cleveland Bridge has manufactured 24 huge steel girders, which will become part of the first bridges that will be built on HS2.
Cleveland Bridge won the contract to supply 1,130 tons of steel girders to the Hs2 early works joint venture LM (Laing O’Rourke / Murphy) in 2019. The JV is building four modular bridges on HS2’s Interchange station site outside Birmingham (Solihull).
Cleveland Bridge pre-assembled 16 of the 20m girders into 50 ton pairs at its factory. This will keep the number of delivery vehicles as low as possible. Over this past week the girders have been moved on site. They will now be assembled into a 65m single span, using 8,500 high-strength bolts.
This steel bridge will span the M42. It will feature a composite concrete deck. Once the fully-decked bridge is assembled at the purpose-built area, it will be moved into position over the motorway. The final bridge will have a total weight of 2,750 tons.
The two modular bridges will be built near the new HS2 Interchange Station, to create connectivity to the Interchange Triangle that sits between the M42, the A45 and the A452. These will be the first permanent structures built by HS2 and will span the M42 and A446. A further two bridges will take roads across the new high-speed line. The road network around the new station is currently undergoing remodelling to move roads out of the way of the new railway line and to connect roads to the new station.
“We're incredibly proud to play a part in the delivery of the UK's largest infrastructure project and this is a significant addition to our track-record for producing structures for iconic developments around the world. It reflects our strategy to maintain our position at the heart of the development of major infrastructure, which utilises our extensive facilities and the capabilities of our highly-experienced workforce, while creating opportunities to develop future generations through our award-winning apprenticeship programme.
“We've been very conscious of the need to continue work during the COVID-19 crisis and have put extra measures in place to ensure we met government guidelines and follow best practice. This has enabled us to continue operating at 100 percent, which has been key to us staying on track to deliver our product on time.”
In total there will be 18 delivers of large steel girders to the HS2 Interchange site. Explore, in Nottinghamshire, is manufacturing the abutments and other major structural components for the bridges.
