The St David Street Footbridge spans the Water of the Leith next to the University of Otago and is a notable feature on the university campus. It is 13 m long and 1.8 m wide. The bridge has four Port Chalmers breccia stone columns with bases and caps, approximately 1.4 m high, each at the end of the bridge balustrade. The deck is made of concrete and asphalt with reinforced steel girders. The decorative wrought iron work on the handrails and the face is a notable feature. The handrail is made of cast steel. Decorative lampposts span the center of the bridge. The footbridge predates the flood control works on the Water of the Leith. Originally, the abutments and wing walls of the bridge were made of masonry (as noted in the original plan). These original abutments were incorporated into the concrete walls of the flood channel when the flood control works were completed in the 1930s.
