7 compelling pictures of the M4 motorway when it was built around West London – MyLondon



Though we often take motorways for granted, there is a lot to be said about the M4.

Originally referred to as the London-South Wales Motorway, the M4 allows smooth travel all the way from from West London to Southwest Wales.

A new road was first proposed in the 1930s, and in 1956 plans were announced for the first major post-war road improvement projects.

Though the first section of the M4 opened way back in 1961, the motorway has seen major expansion over the years. Continuous work all the way into the 1990s has seen the M4 become one of the biggest motorways in the UK.

The starting point for the M4 is Chiswick, and it ends at Pont Abraham in Carmarthenshire. The full length of the M4 motorway is 189 miles, and traffic passes major places such as Bristol, Reading, Cardiff and Swansea.

The M4 also goes past Heathrow Airport, and gives access to all terminals via Junction 3 and Junction 4B.

According to Highways England, this mega motorway carries over 130,000 vehicles every day. Pretty good going if you ask us.

These photos give us an insight into the history and creation of this miraculous motorway.
