The A466, also known as the Wye Valley Road, is a road from Hereford, England to Chepstow, Wales via Monmouth, Tintern and the Wye Valley.
The road was largely developed during the late 18th and early 19th centuries by turnpike trusts in Herefordshire and Monmouthshire. It replaced the River Wye as the principal means of transport to Tintern before the construction of the Wye Valley Railway in the late 19th century. The A466 remains an important route for local residents and tourists, and now provides access to the Severn Bridge on the M48 motorway.
