A £1.5billion scheme by Highways England to improve the A14 trunk road between Cambridge and Huntingdon. The aim being to relieve congestion, unlock economic growth, improve safety and enhance the local environment. Weathering steel was utilized to provide the required durability with minimal future maintenance. One of England’s largest road improvements, the development included a 750m long viaduct over the River Great Ouse and two new bridges at Bar Hill interchange, incorporating over 9,000 tons of weathering steel.

The project, by Cleveland Bridge UK, won a Structural Steel Design Award (2020) with recognition for the innovative solutions the design team employed to minimize disruption and optimize the programme. Flawless execution on site included installing two bridges, each weighing over 1,000 tons, in just 11 hours.

The viaduct was completed on budget and ahead of schedule with approx. 83000 M30 weathering steel TCBs deployed.
