A74(M) and M74 Motorways - Junction Renumbering

Junction Renumbering

Following the building of the original section of the M74, the motorway was numbered south-to-north, with Draffan being junction 1 and Maryville junction 6. When the M74 was extended south of Draffan in the late 1980s, it was renumbered north-to-south. Raith remained as J5, while Maryville became J4, allowing for later extension towards Glasgow. The original junction 1 at Draffan was closed, with a new junction 9 (Kirkmuirhill) replacing it, using the southbound carriageway of the old A74 as a slip road. The remains of the semicircular access road to the southbound carriageway EW still visible at Draffan Road, with the Blackwood slip road now used as an access road to new housing. In preparation for the extension to meet the M8 south of the Kingston Bridge, junctions 1–3 were renumbered 2A, 3, and 3A to accommodate the new junctions.
