M6 motorway

The M6 motorway is the longest motorway in the United Kingdom. It runs from a junction with the M1 near Rugby in central England, passes near Coventry, through Birmingham and near the major cities of Wolverhampton, Stoke-on-Trent, Manchester, Liverpool and Preston, and runs to the north of Carlisle, close to the Scottish border.

It is often claimed to be the busiest motorway in the country, although the M25 may also lay claim to this dubious distinction, depending on the measurement used. It is also sometimes referred to as the "Backbone of Britain" as it forms part of the central road corridor between Glasgow and London, connecting Scotland and the industrial North of England to the financial and governmental heart of the country in the South East.

From the M1 to the M6 Toll split near Birmingham, the M6 is part of the unsigned E-road E24. E5 joins the M6 Toll from the M42 and then uses the M6 to its north end at Carlisle, where it continues along the M74.
