Salmon Weir Pedestrian and Cyle Bridge, Galway

<p>Droichead an Dóchais, is a new pedestrian and cycle bridge crossing the River Corrib in Galway City, translating as Bridge of Hope from the Irish language. The bridge is located 24m from the existing 7-span historic masonry arch Salmon Weir bridge, dating from 1820 and connecting the historic Galway Cathedral and Mercy Convent. The new crossing provides a separate, safe, active travel connection for over 10,000 pedestrians and cyclists daily, removing conflicts between them and vehicles and helping to reduce dependency on private vehicles in line with national transport and planning policies.</p><p>The crossing comprises a 3 span bridge crossing Perrse’s Distillery River (West), the River Corrib (central) and the Friar’s River (East). The structural system of the main span is a fully integral, single span with a variable depth central steel box girder and variable width cantilevered walkways. Spanning 55 meters over the watercourse, the bridge’s semi-elliptical arch, steel central spine beam and transparent handrails create an illusion of the structure hovering over the river. Post-tensioned connections are provided to the foundation at both sides of the main span, minimising hogging at midspan, structural deflections and vibrations under live load. The central spans spine beam is reminiscent of a salmon’s profile, reflecting the culture and heritage of salmon fishing in the River Corrib.</p><p>The design positions the bridge as more than a piece of transport infrastructure; it is an architectural and urban amenity, a landmark development and a focal point in Galway City which enhances the quality of life for residents and visitors alike.</p>
