Bascule Bridge

The Bascule Bridge is a Grade II listed structure made of riveted I-section steel girders. It features a slightly humped deck with an opening joint at the center, supported by two pairs of large circular piers that are rendered over iron or steel, with lateral braces separating each pair. The low abutments are constructed from concrete blocks.

The superstructure includes vertical and raked steel posts, horizontal steel beams, and lateral braces across the top of a lighter lattice work. The opening mechanisms, situated over the two sets of piers, consist of pairs of curved racks that swing down onto pegged beams to lift the cantilevered road sections. Above each pair of racks, there are large angled steel plates within a high vertical superstructure of lattice steelwork, with girders curving down to connect to the top of the main superstructure.

In front of the steel plates, a frame houses the gearing mechanism, which includes small gear wheels, although the original power source is no longer present. The road is bordered by footways that are supported underneath by curved beams. These footways pass under original steel archways connected to the opening mechanisms and feature plain steel railings. Many of the steel girders are labeled 'Cargo Fleet England', with a few marked 'Lanarkshire'.
