The Gade Valley Viaduct is a multi-span composite twin deck viaduct carrying the M25 over the Grand Union Canal, the River Gade, London-Birmingham Railway and a major road.

We delivered a scheme featuring multiple bridge spans, stair access and a safe working platform to the underside of the entire structure for strengthening works. This project featured our user-friendly LX133 beams which include a middle chord making construction must easier and safer.
