The stone bridge consists of three semi-circular arches, each with three wide ribs. Its piers have pointed cutwaters and, on the western pier, these end just above the springing point. On the eastern pier, however, they narrow at the parapet and continue up into the side walls of the fortified arch.

This masonry arch runs over the roadway and contains a room, 36ft long by 10ft wide, under a pitched roof with rounded ends.

The bridge is 114ft long and 24ft wide between parapets. This is the result of widening since the original construction: 3ft 6in on the upstream side and 5ft on the downstream side.
