[1][2] The Old Bridge is built of iron and pennant stone, with a shallow, elliptical arch.
The sides have an iron cross lattice with applied flower casts and vertical chain-moulded struts, and above it a balustrade of interwoven ropes beneath a heavy rope handrail.
At either side are abutments, surmounted by panelled ashlar piers to the balustrades.
Once it had fulfilled its purpose, the temporary bridge was lifted off its base by two barges on a rising tide, and moved upstream to a new location, where it still exists as the Langton Street Bridge.
