 The chains are anchored in tapering tunnels, long, on either side of the bridge and plugs of Staffordshire blue brick infilled to prevent the chains being pulled out of the narrower tunnel mouth.After completion of the chains, vertical suspension rods were hung from the links in the chains and large girders hung from these.The girders on either side then support the deck, which is higher at the Clifton end than at Leigh Woods so that it gives the impression of being horizontal.
