M6 Carlisle - Gretna
- Completedunder motorway restrictions
- £ 174m

- Region: North West

- 10 km
- 6.2 miles
Upgrade of the existing A74 dual carriageway between the terminus of the M6 at Greymoorhill to the Scottish Border, where the A74(M) commences, to dual three-lane plus hard shoulder motorway standard, including the replacement of a railway bridge and construction of a new parallel service road.
It will close the "Cumberland Gap" where six miles of sub-standard dual carriageway connects two modern three lane motorways.
There is speculation that the A74 number will be replaced with M6, and upon completion, the A74(M) and M74 in Scotland will assume the M6 number to provide a consistently numbered cross-border route. It seems far more likely that the M6/A74(M)/M74 route number sequence will remain for the forseeable future.
