The B4574 is a road linking the villages of Pont-rhyd-y-groes in Ceredigion, Wales, and Devil's Bridge, 12 miles (19 km) east of Aberystwyth, and noted for three bridges built one above each other as well as for its falls[1] and narrow gauge steam railway.[2] The route is six miles (9.7 km) long, and has been described by the AA as one of the ten most scenic drives in the world[3][4][5]
The road runs partly along a section of the upper Ystwyth valley, passing the remains of the Cwmystwyth Mines,[6][7] a monumental arch built to commemorate George III's golden jubilee, and the Hafod Estate.[8]
