Our proposal, with architects Softroom, won an RIBA competition to replace an existing bridge on a site across the Leeds-Liverpool Canal. It is intended to act as a catalyst for the wider regeneration of a derelict former industrial area.

The form of the competition scheme was generated by resolving constraints of the site and the requirements for ramp access on each approach. The structure is conceived as a pair of deep rectangular glulam beams placed within the balustrade zone of the bridge.

These are fixed ended at the straight ramp sides in order to keep the overall depth as shallow and elegant as possible. The elbows are torsionally stiffened within the triangular balustrade zone at the abutment. The deck is a simply supported timber joist structure spanning between the primary beams.

Concrete abutments contain reinforced soil which supports shallow zig-zag ramps, planting and steps on the West bank, negating the need for long balustrades in these areas and forming a viewing terrace to the adjacent playing fields.

The competition design was intended to be flexible in nature so that it could be modified as necessary during the rigorous detailed design process later, while still maintaining the elegance and simplicity of the original concept.
