Bont Fawr, Dolgellau, is a substantial road bridge dating in part from l638. It was rebuilt above the spandrels in the early 19th century and largely remodelled in 1870 by widening on the upstream side and the addition of two new arches at the north end. A modern concrete span now crosses the A470 and a modern footbridge obscures the upstream side. There are 7 arches and plain pilasters rise from buttresses on downstream side.
