Port Salford Canal Crossing


Hochtief UK / Buckingham Group JV for Peel Ports

Project Description

This new crossing of the Manchester Ship Canal is part of an improvement of the road links to Port Salford - the UK’s first tri-modal inland waterway port. It is a vertical lifting bridge carrying dual carriageway, combined footway/cycleway and a segregated single lane tramway for future connection to the Manchester Metrolink. Opening of the bridge will allow a shipping corridor of 28m wide and 24.8m high for the passage of tall ships. The deck is a steel orthotropic plate which is lifted from four hollow towers which house counterweights connected to the deck by steel wire ropes. Lifting is activated by four synchronised winches located in plant rooms at the base of each tower.
