The A74(M) and M74 motorways are two major motorways in Scotland, running continuously from the southern outskirts of Glasgow to the English border at Gretna. 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 Numbering confusion below.
The M74 (from Junction 4 southwards) and A74(M) are part of the E05 Euroroute which runs from Greenock to Algeciras. North from Junction 4, the E05 takes a short stretch of the M73 connecting to the M8, then proceeds westwards through Glasgow to Greenock; and southwards continues on the M6 through England.
Construction of the extension began on 29 May 2008, with a completion date of August 2011. The project contract was signed on a fixed price of £444 million and a £12million allowance for grouting of old mine workings.
There is a long-standing plan, once the southern extension of the road is complete, to rename the motorway as part of the M6, creating a 350-mile motorway from Rugby to Glasgow. When the A74(M) was constructed in the 1990s, many of the signs were given patches with the A74(M) number on - these patches can be peeled away to reveal "M6" underneath. One such sign can be seen at the VOSA checkpoint just past the Crawford/Thornhill on-slip states that it is the "M6 South" instead of the "A74 (M)" South. However, when the Scottish Executive was established in 1999, taking over for responsibility for roads in Scotland, Sarah Boyack said that "We have no current plans to rename or redesignate the M74 or A74(M) motorways between Glasgow and the border as the M6". The current Scottish Government have not commented further on the matter.
