Description
Tanhouse Bridge features stone-coped brick abutments with blue engineering brick chamfered vertical corners. Iron strips have been applied to protect the corners on the towpath. The bridge consists of five fish-bellied cast iron 'T'-joists, each with a bottom flange measuring 170 x 40mm and a depth ranging from 210 to 280mm. The outer joist is made of cast iron and includes pockets for a timber guard rail, all resting on stone padstones. The roadway is supported by later corrugated iron placed between the joists. An oval cast iron plate displaying the bridge number is affixed to the abutment beneath the bridge. The towpath is revetted with large cow-nosed blue engineering bricks made by the Tibbington Company of Tipton, likely installed between 1880 and 1890 when the canal was renovated by the Shropshire Union Railways and Canal Company.
