The Maryhill and Lomond Motorways were developed to provide a radial route from the north flank of the Ring Road and a northern bypass of the city.
The Glasgow Inner Ring Road was planned as an urban motorway route around the city centre. This page covers the unbuilt half of that ring.
The Hamilton Motorway was proposed as a radial route, connecting the east flank of the Ring Road with the M74 at Maryville. It was to have been similar in design to the Monkland Motorway.
Before the M77 there was the Ayr Motorway. A route planned to link the M8 with the south of the city and Ayrshire. Wider and much larger in scale than the M77.
