New HS2 Birmingham bridge moved into final position
In a major construction operation, HS2 has moved a 1,600 tonne steel and concrete bridge into place in Saltley, Birmingham in just eight hours.
The new Aston Church Road bridge, which is 84 metres long and 21 metres wide, was moved over the existing Birmingham to Derby railway line. It will also sit above the new HS2 tracks as high speed trains travel in and out of Birmingham.
The bridge provides an upgraded, safer section of Aston Church Road including cycleways, which connects Saltley, Washwood Heath and Nechells in north-east Birmingham.
The technique of building the structure on land next to the existing railway and moving it into position in one operation over one weekend, significantly minimises disruption to rail passengers.
Heavy lifting engineering experts Mammoet moved the bridge into place using two 128-wheeled self-propelled modular transporters (SPMTs) across a matting bed put down over the tracks by Pod-Trak to provide a level surface.
The bridge now sits on three structures - an abutment to the West of the existing rail tracks, a pier consisting of two columns on the East of the existing tracks, and an abutment to the East of the pier.
