The installation of a 65-metre bridge over the M42 motorway near Solihull was completed in just two day, finishing 22 hours ahead of schedule on 9th August 2020.
It won’t be carrying the new railway – it is part of road network remodelling in the vicinity of the planned Interchange Station.
The 2,750-tonne concrete and steel bridge structure was fabricated alongside the motorway over several months and then wheeled into place during a motorway closure using self-propelled modular transporters (SPMTs).
The work was led by concrete structures specialist Expanded – part of the Laing O’Rourke group – working for HS2 enabling works contractor, LMJV (Laing O’Rourke and J Murphy & Sons Joint Venture). Other key players in the project included steelwork contractor Cleveland Bridge and Dutch heavylift specialist Mammoet, which moved the finished structure into place in just 105 minutes.
LMJV project director Simon Russell said: “This is British construction, design and engineering innovation at its finest. Major components of the bridge and its supports were built offsite under safe, high quality conditions, then transported to site for assembly. Advanced digital capabilities allowed us to design all elements of the structure in a virtual world, before building it for real, and I am delighted that the work was completed safely and ahead of schedule.”
