A74(M) and M74 Motorways

The A74(M) and M74 motorways form a major motorway in Scotland. Following an extension opened on 28 June 2011, it connects the M8 motorway west of Glasgow to the English border at Gretna, creating an alternative route for traffic moving from the south to the west of the city. In conjunction with the M6 motorway, it forms one of the two major cross-border routes between Scotland and England. It is part of the unsigned international E-road network E05. Although the entire route is usually referred to as the M74, more than half of its length is officially designated as the A74(M); see naming confusion below.
