Thought to be the only laminated greenheart timber bridge in the country, Dutton Horse Bridge carries the towpath of the Weaver Navigation across the back river, not far from Locke's 1834 masonry viaduct.
The bridge has two spans: 100ft 7in and 101ft 7in. Each consists of a pair of timber long segmental, semi-elliptical arches set on cast iron bearings. The timber for the arches was mechanically laminated. Triangulated timber struts support the footway above and transverse triangulated bracing in cast iron connects the pairs of arches.
The central pier sits on two round brick columns filled with concrete. The brickwork was laid inside coffer dams made of greenheart timber planking. These were found to be still in place when the substructure was inspected in 1993.
The engineering brick abutment structures sit on greenheart timber pilings and were filled with lime waste and cinders. The bridge is skewed at 45 degrees to the abutments.
The bridge's deck is 8ft wide and was originally made of close-set 2in thick greenheart timber slabs, all covered in asphalt. Its parapets are timber post and rail, bolted to the deck stringers.
Saner was engineer to the Weaver Navigation Trust.
