The M40 is the LondonBirmingham Motorway. The High Wycombe and Beaconsfield bypasses were originally allocated the number A40(M). For many years, it only ran as far as Oxford, bypassing the A40. However, the plan had long been to extend it to the Birmingham area, which happened in 1989-1991. Some proposals had it reach the M5 via what is now the M42.

Between the junctions with the A34 and the M42, the M40 forms part of the North-South E05 that runs from Scotland to Spain.
