Where does M6 start and finish?

The M6 starts at Junction 19 of the M1 at the Catthorpe Interchange, near Rugby, and then routes around Birmingham, Staffordshire, Stoke on Trent and between Liverpool and Manchester. It goes past Preston, Morecambe and into Carlisle before ending at Gretna, in Scotland, and connecting to the A74(M).



The M6 motorway in the United Kingdom runs from Catthorpe, Leicestershire to Gretna, Dumfries and Galloway.

Here are the key details:

  • Southern Terminus: Junction 19 of the M1 at Catthorpe Interchange, near Rugby. This is where it branches off from the M1 to head northwest.
  • Northern Terminus: The Gretna Interchange at the Scottish border. Here, it becomes the A74(M), which continues to Glasgow as part of the M74.

Important notes: It is 232 miles (373 km) long, making it the longest motorway in the UK. For its entire length, it forms a crucial part of the west-coast route between London and Glasgow. The section north of Junction 44 (Carlisle) is also part of the European route E05.

So, in summary: Starts near Rugby, England, and finishes at the Scottish border near Gretna.
