The M73 is a motorway in Glasgow and North Lanarkshire, Scotland. It is 7 miles (11 km) long and connects the M74 motorway with the M80 motorway, providing an eastern bypass for Glasgow. The short stretch between Junctions 1 and 2 is part of unsigned international E-road network E05, where it continues along the M8 through Glasgow. To the south, the M74 motorway is also part of the E05.

Starting at the M74 junction 4 (M73 junction 1) by the River Clyde, it proceeds north with Birkenshaw to the east and crosses the Whifflet railway line before meeting the M8 and A8 at a three-level interchange, west of Swinton. Immediately afterwards the North Clyde railway line and then passes alongside Woodend Loch before reaching junction 2A at Gartcosh. There is then a further 2 miles (3.2 km) of motorway, before traffic exits onto the M80 westbound.

The road is a dual 3 lane road between junctions 1 and 2, and a dual 2 lane road between junctions 2 and 3. It is subject to the national speed limit.

History and future plansEdit

Construction began in 1969 with the motorway opening between May 1971 and April 1972.[2] Junction 2A was added at a later date.[1]

In 2011, the northern end was extended as part of the M80 completion project. This connects the motorway into the completed M80 at a new interchange.[3]
