BIGSWEIR BRIDGE Chepstow-Monmouth Rd, 1826-29 SO 539 051 {N51o 44’ 33.5” W2o 40’ 6.0”}
A single arched bridge of 164 feet gracefully spans the Wye River just north of Llandogo on the A466 in a lovely sylvan setting. The four truss arched ribs were cast at Merthyr Tydfil. It was part of a toll road which was authorized in 1824 and was designed by G.Hollis of London. Later, in the mid 19th century two masonry arched flood spans were added at either end. Although only 12 feet wide, it continues to carry the modern traffic albeit in one direction at a time.
