The SAS 13 railway bridge is now fully functional after carrying its first freight train.
Tracks reopened today (Monday 23 May) on the Stechford to Aston freight line in Birmingham following the installation of a massive 2,600-tonne bridge* by Skanska in partnership with Network Rail and HS2.
At 92 metres long, the steel and concrete structure becomes the longest single span railway bridge in the Midlands.
It needs that clearance underneath so future tracks for Britain’s new zero-carbon railway can be built below for HS2 trains to access its Washwood Heath depot.
The demolition of the old railway viaduct and installation of the new bridge has closed this connection to Birmingham rail freight terminal for 23 days.
But today the first train passed over the new structure, reopening the important rail freight route and marking a huge milestone for the project.
Patrick Cawley, director for ‘On Network Works’ for Network Rail and HS2, said: “Seeing the first train pass over this iconic structure is a proud moment for the hundreds of people who’ve worked throughout the pandemic to make this new bridge a reality.
“It’s also a key part of the jigsaw to ensure the existing railway network works in harmony with HS2. I’m conscious this work has disrupted some passenger journeys over recent weeks and I’d like to thank CrossCountry customers for their patience while we carried out this major project.”
Rosario Barcena, Skanska Rail programme director, said: "Installing a railway bridge over an existing railway line is a complex engineering project that requires a huge amount of skill and dedication from all those involved. To have delivered this on time and despite of Covid-19 restrictions is a fantastic achievement and testament to the team involved."
Building and installing the bridge, known as SAS 13, involved precision planning and engineering and the use of some heavy-duty equipment.
Earlier this month the structure was driven into place by remote-controlled vehicles after being pre-assembled on site in a civil engineering project which has taken over two years.
Building it on site reduced carbon emissions and cut the number of lorry movements on local roads, minimising impacts on the local community.
*With the tracks and ballast now finished on top of the bridge, the total weight of the structure is 3,200 tonnes.
In numbers, the SAS 13 bridge:
- Weighs a total of 2,600 tonnes (3,200 with the railway weight now on top)
- Spans a distance of 92 metres
- Is held together by 26,715 bolts weighing a total of 25 tonnes
- The whole project uses 3,601 cubic metres of concrete
- And 1,118 tonnes of steel (equivalent to 940 Mini Cooper cars)
- Is an investment of £85m to ready the existing railway for HS2
- End to end the new metal bridge is 92 metres long – four metres shorter than London’s Elizabeth Tower – the home of Big Ben.
