The bridge over the River Wye forms the connection at that point between England and Wales. It was built in 1826-9 to a design by Charles Hollis of London and constructed of cast iron and sandstone, the casting having been done at Merthyr Tydfil. The main span is 55 yards (50m). For today's traffic it is a single track bridge, the crossings being controlled by lights. It was originally a toll bridge and the toll house can just be seen on the Welsh side (left in the photograph).
