M18 motorway (Great Britain) and 12 June 2015.

It runs from the east of
M62 motorway and Manchester started in 1971, with the construction of a link between the M57 and M6 motorways. Simultaneously, a contract to link the M6 with Manchester was underway, which required land drainage and the removal of unsuitable earth. This section was completed in August 1974, creating a continuous link between Ferrybridge and Tarbock. Two motorways were planned, the M52 from Liverpool to Salford and the M62 to link Pole Moor with the Stretford–Eccles Bypass. The first part of the M62 to be built was the Stretford–Eccles Bypass, which is now the section between Junctions 7 to 13 of the M60.
