The A74(M) and M74 are two connected motorways in Scotland. They act as one motorway, usually just called the "M74". The motorway starts at the border with England. Here, the M6 motorway turns into the A74(M) motorway. The motorway connects the M6 with Glasgow and the M8. About halfway between the border with England and Glasgow, the A74(M) becomes the M74. Together, the motorways are 85 miles (137 km) long.^[1]
