Telford's Holyhead Road in Wales—the first super highway

The London to Holyhead Road is widely recognised as one of Telford's greatest engineering achievements, particularly its landmark suspension bridges at Menai and Conwy. However, it was the dramatic improvements to the route through north Wales that proved most beneficial to the growing stagecoach traffic between newly unified England and Ireland. Even though the railways soon took over, the road set an early benchmark for future road construction projects worldwide. This paper describes the north Wales section which, two centuries on, is still very much in use, along with its many innovative bridges, toll houses, depots and street furniture.
