HistoryIt 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 {{convert|12|mile}} 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] DesignIt has three arches of {{convert|42|ft}} span, and is {{convert|22|ft}} clear over the river.[4] The total length of the bridge is {{convert|146|ft}}.[4] The width between the parapets is {{convert|13|ft|9|in}}, 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] References1. ^{{cite book|last=Skempton|first=A.
