A TEMPORARY access bridge is now allowing construction vehicles to avoid neighbouring roads during construction of the 3.4km Colne Valley Viaduct on the HS2 route.
Running alongside what will become the UK’s longest viaduct, the temporary bridge allows vehicles to cross a series of lakes and waterways near Denham.
As well as taking lorries off public roads, the 800m temporary bridge, completed in February, is also used to get equipment out to where the viaduct’s piers are being built in the lake.
Lorries making deliveries to site arrive from the M25 and follow a 6km internal access route.
Construction of the viaduct is now well underway, with all the foundation piling for the 56 piers now complete.
Almost 200, out of a thousand, deck segments have been installed.
