The A74(M) and M74 form a major motorway in Scotland, connecting it to England. The routes connect the M8 motorway in central Glasgow to the Scottish-English border at Gretna. They are part of the unsigned international E-road network E05. Although the entire route is colloquially referred to as the M74, for more than half its length, south of Abington, the road is officially the A74(M); see naming confusion below.
