Swing Bridge

Cass Hayward’s swing bridge design projects include the reconstructions of Dutch River Bridge at Goole and of Adur Ferry Bridge, Shoreham. Our design for Dutch River Bridge included the rack and pinion driven cable stayed swing span, two static highway approach spans and the foundations. At Shoreham we designed an offline solution with electrically-operated central balanced swing spans over the navigation channel with three static composite approach spans on each side. Monopile foundations fitted with precast shell pile caps helped to minimise construction activity in the estuary. We acted as independent checker for the A63 cable-stayed River Ouse Bridge for the dual carriageway bypass of Selby.

We have been involved with assessment and upgrading works design for the railway swing bridges at Goole and in East Anglia at Reedham, Somerleyton and Oulton Broad. Similarly with assessment design for Brunel Lock Bridge and Junction Lock Bridges in Bristol.
