A specialist cantilever process has been used for the first time in the UK by HS2 to build the first section of the 472-metre-long River Tame West Viaduct in the West Midlands.
The viaduct, which will eventually carry three rail tracks, is a precast segmental viaduct at the northern tip of the Delta Junction, crossing the River Tame near Water Orton and joining the Curdworth Box which will take high speed trains over the existing Birmingham to Derby railway.
Construction of the viaduct’s piers started in 2023, with the first spans of the three track section completed in Spring 2024. This initial phase involved placing the segments onto two 42 metre truss beams, moving them into place with a skidding trolley, and securing them by post-tensioning techniques.
