The Forth Road Bridge (not to be confused with the much older Forth Bridge, a railway bridge) is a suspension bridge carrying road traffic on the A90 over the Firth of Forth. It was opened by the Queen in September 1964 and was a toll bridge until this was abolished by the Scottish Executive in 2008. It is a vitally important link between Edinburgh and Fife for both commercial and commuter traffic. Following concerns about the bridge's longevity and the need for increasingly disruptive maintenance the Forth Replacement Crossing project is currently building a replacement bridge along with new approach roads. The existing Forth Road Bridge will be retained for use by buses, taxis, cyclists and pedestrians.
Though not a motorway, it opened simultaneously with the first motorways in Scotland - a short section of the M90, which formed part of the northern approach to the bridge, and its short spur the A823(M).
