The M40 motorway ( English for 'M40 motorway') is the second motorway in the UK road network that connects London with Birmingham .


The first part of the M40 was built in the 1960s and connected London to the A40 at Stokenchurch on the top of Chiltern Scarp , a few miles from High Wycombe . On some maps, the original High Wycombe bypass is shown as the A40 (M) instead of the M40. In 1974 the motorway was continued to Chilworth, about 8 miles east of Oxford, with a four-lane continuation into the city. Thus, the mostly four-lane connection between the capital and the university city of Oxford was completed, including about 32 miles of motorway.

At the end of the 1980s, construction began on the continuation to Birmingham in order to relieve the previous motorway connection via the M1 and M6 . First the M42- Warwick connection was opened in 1989 , followed in 1991 by the entire route from Oxford to Warwick. An alternative route had to be chosen east of Oxford to avoid the Otmoor marshland . To date, the Oxford-Birmingham motorway is the last major new motorway to be built in England.

Accident on November 18, 1993

The M40 hit the headlines on November 18, 1993. The night before, a minibus with 15 students from Worcestershire crashed not far from Warwick. The group came from a concert at the Royal Albert Hall in London. The cause of the accident was that the teacher who was driving the bus fell asleep at the wheel. Ten students and the teacher died of their injuries at the scene of the accident, two other students later died in hospital. Only two students survived.

The accident led to seat belts becoming mandatory equipment for buses and coaches, although there has been no obligation to wear seat belts in buses and coaches.

An anecdote

The fact that the M40 from London to Oxford and leads the M11 from London to Cambridge, led to a famous sketch in an episode of the BBC - series Yes, Minister .

Jim Hacker, a member of the government and protagonist on the series, wondered why Britain has highways to these venerable university towns but not to important seaports like Dover or Felixstowe. Sir Humphrey Appleby, the permanent private secretary, stated that the highway system was developed by civil servants trained at either one university or the other. The officials' opinion, like Sir Humphrey's statement, can be summed up in another episode: "Of course, I believe in universities, Minister: both"


  • In the film Thunderbird 6 , the M40, which was not yet released for traffic at the time, represents the fictional M104 motorway.
  • The M40 can also be seen in the opening scenes of the film "The Vicar of Dibley", a bird's eye view of the Chiltern scarp (locally known as The Grand Canyon ) and the Oxfordshire countryside.
  • In the episode "The Pitch Fork Killer" from the British crime series " Inspector Barnaby " (Season 3, Episode 3) from 2000, the M 40 can be seen on the section between High Wycombe and Oxford in the Chiltern Hills.
