 The road network in the lower Wye valley remained essentially undeveloped during the rise of the Valley's industrialisation, until a series of Turnpike trusts were authorised during the 18th century.It was not until 1828 that the current Wye Valley road, the A466, was first constructed.The area became more accessible by road to much of the country with the building of the M50 between the M5 and Ross-on-Wye, and the opening of the Severn Bridge (now part of the M48) in 1966.
