History

The bridge in winter

It was built in around 1764, with William Mylne acting as both designer and contractor.^[1] Its construction was authorised by an Act of Parliament obtained in 1764, for 12 miles (19 km) of road that would cost 6560l, including the "substantial" bridge at Fairnilee.^[2]

It was listed as a Category A listed building in 1971.^[3]

The bridge was substantially rebuilt between 1987 and 1988, with the addition of reinforcing concrete.^[4]

Design

The bridge viewed from the south

It has three arches of 42 feet (13 m) span, and is 22 feet (6.7 m) clear over the river.^[4] The total length of the bridge is 146 feet (45 m).^[4] The width between the parapets is 13 feet 9 inches (4.19 m), but the cutwaters are carried up to form semi-hexagonal pedestrian refuges.^[4] The piers and abutments are made from block masonry, and the rest of the structure is made from rubble.^[4]

The bridge carries the A707 public road across the River Tweed.^[5]
