Long-Span River Crossing

A multi-span river bridge with deep foundations, tall piers and a superstructure erected over water, plus approach viaducts on both banks.

01Project overview

The scope, in context

The crossing replaces a constrained existing route with a wider, higher structure clear of the flood level. Foundations, piers and deck are programmed around the working season in the river.

Method planning covers well or pile foundations, pier construction from temporary platforms, and segmental or girder erection with river navigation maintained.
