Bridge Projects

Mersey Gateway, temporary trestle, Bascule Bridge

Client: Woodburn Engineering Ltd.

As part of the temporary works contract on the New Mersey Gateway Bridge, the works access trestle for the bridge foundations required a moveable span to allow access to the navigation channel on the Mersey River, close to the south bank. In conjunction with Woodburn Engineering Ltd, a solution utilising a counterweighted bascule span (lifting bridge) was proposed. The solution had to account for construction vehicles (SV80 loading), LM1, LM2 & LM4 load models, vessle impact, hydrodynamic loading, and wind loading.
