piers, those flanking the lifting bascule over the main channel having timber buffers. The bridge has lattice girder parapets which are ramped-up to the lifting section.

The plinths bear plaques on 2 sides, the north-east plinth with a commemorative inscription recording details of construction and the opening of the bridge by HRH the Prince of Wales on 19 July 1925; the other plinths have plaques bearing polychrome painted reliefs of the Grimsby Corporation Arms.

The decking of the lifting span is primarily wood on a latticework of steel beams with a skid resistant and waterproof surface of an epoxy resin material. Gates at each end of the lifting span, close automatically as the bridge is raised to close the span to vehicle and pedestrian traffic.
