This innovative pedestrian bridge provides a unique landmark structure that links the historic city centre of Stirling with the neighbouring, modern Forthside development. In addition to its functional requirement to enable pedestrians to cross a railway line, the client wanted a contemporary design of high quality that would make a lasting contribution to Stirling’s architectural and cultural heritage. The solution also promotes the presence of Forthside and symbolises the regeneration of the city centre. The bridge is based on an inverted ‘fink’ truss but insufficiency removed from its generic roots as to be unique. Two tapered and inclined truss planes are arranged to create a twisting form. Both the lifts and stairs that provide the approaches are landscaped features of the support piers. The bridge is a visually and structurally independent structure that connects the two approach assemblies. The defining feature of the bridge are the up-stand trusses to either side of the deck with steel masts and cable bracing but, critically, devoid of top chords.
The twisting transitional form of the bridge is strongly reflected in the parapets which ‘warp’ in concert with the structure. Solid glass parapets on each side are inclined to the deck at a constant angle of 12 degrees. Above the handrail, further glass panels are hinged to mimic the varying angles of inclination of the trusses. For the user, this provides an eye-level integration between the deck and the twisting trusses. This visual impact is enhanced by the way the trusses open out towards the approach structures.
