This design and build scheme included the construction of a new 10km two-lane, single carriageway bypass. It involved the construction of embankments, cuttings and overbridges across minor roads. A new 100m long, cable-stayed, swing bridge was installed to cross over the River Ouse, Selby Canal and railway lines.

Due to the poor existing ground conditions in the surrounding flood plain, the approach embankments were founded on piles. To provide a low maintenance strategy, the integral bridge design concept was used for the fixed bridges as far as possible (including two rail bridges). The design was environmentally-aware with landscape proposals and measures to enhance the biodiversity value of the project, while maintaining the navigability of the River Ouse for regular vessel access.

Rendel undertook tender design services at tender stage followed, subsequent to contract award, by full engineering design as the contractor’s designer.
