The Menai Suspension Bridge (Pont Grog y Borth) is a suspension bridge between the island of Anglesey and the mainland of Wales. Prior to the bridge's completion in 1826 the island had no connection to the mainland and all movement to and from Anglesey was by ferry (or, with difficulty, on foot at low tide). However, the Act of Union 1800 increased the need for transport to Ireland, and with Holyhead as one of the principal terminals to Dublin it was decided that a bridge was needed. Thomas Telford was assigned the task of improving the route from London to Holyhead, and one of the key improvements was his design of the suspension bridge.
