M8 Motorway (Scotland) - Construction

Construction

With the advent of motorway-building in the United Kingdom in the late 1950s, the M8 was planned as one of a core of new motorways, designed to replace the A8 road as a high-capacity alternative for intercity travel. The motorway was constructed piecemeal in several stages bypassing towns, beginning in 1965 with the opening by Minister of State for Scotland George Willis of the bypass of Harthill. In 1968 the Renfrew Bypass was opened as the A8(M), becoming part of the M8 when the motorway to the west was connected. The Glasgow inner city section was constructed between 1968 and 1972, using a scheme outlined in the Bruce Report, which was published as the Second World War was closing, and which set out a series of initiatives to regenerate the city. Bruce's scheme evolved into what would become the Glasgow Inner Ring Road, a motorway "box" which would encircle the city centre, connected to the Renfrew Bypass at its south western corner, and the Monkland Motorway (built over the former route of the Monkland Canal) towards Edinburgh at its north eastern corner. Together, these three sections of motorway make up the present day M8.

Most of the motorway's length was complete by 1980. Since then, the only additions have been a new interchange with the M80 motorway in 1992, a 4-mile (6.4 km) eastern extension from Newbridge to the then-new Edinburgh City Bypass in 1995, and the new junction on the approach to the Kingston Bridge in Glasgow connecting to the new M74 extension in 2011. The Scottish Government plans to complete the one remaining unfinished section between Baillieston and Newhouse in the near future, providing three new motorway junctions to serve Coatbridge, Bargeddie and Holytown amongst others.
