Musgrave's Bridge is a single-span bridge, erected in about 1805. It was designed by John Rennie the Elder (1761-1821), who was a leading civil engineer during the first two decades of the 19th century. The land drainage scheme that took place in the East, West and Wildmore Fens between 1802 and 1810 for landowner Sir Joseph Banks (1742-1820) was Rennie’s first major drainage scheme. The East, West and Wildmore Fens north of Boston comprised over 60,000 acres, and were liable to flooding from rainfall on high ground to the north. Rennie’s scheme involved the engineering of catchwater drains to carry rain water from higher ground to a new outfall on the River Witham south of Boston. The rainfall on lower ground was carried by a new system of internal drains to the existing Maud Foster Sluice. Musgraves Bridge was an accommodation bridge, maintaining pre-existing access from West Fen Lane to Musgraves Farm over the West Fen Catchwater Drain. The bridge comprises an elliptical arch with red brick voussoirs, flanked by splayed abutment walls. This early 19th century bridge remains largely unaltered.
