M4

The M4 is a motorway in the United Kingdom that connects London and South West England. It runs from London to South Wales and it is a crucial part of the English transport network.

The M4 was first proposed in 1927 and construction began in 1958. It was completed in 1971, running from London to Reading, Berkshire and later extending to South Wales.

The M4 is one of the major roads in the UK and a significant part of the economy. The M4 has been upgraded in certain sections and currently consists of 146 miles (235 km) of motorway.

The M4 is one of the safest motorways in the UK. According to the Department of Transport (DfT), the M4 had a collision rate of just 0.41 per million vehicle kilometres between 2017-2018. This is lower than the UK major-road average of 0.71.
