It begins in Chiswick and ends in Pont Abraham in the Carmarthenshire region. The M4 runs 189 miles and passes through several significant cities and towns, including Reading, Bristol, Cardiff, and Swansea. As Heathrow Airport passes, Junction 3 and Junction 4B offer access to all five terminals. The M4 corridor is the term used to describe the region of the UK that borders the M4.

There are just three motorways in Wales, including the M4. On the M4, a toll bridge spans the River Severn; motorists must pay the toll to enter Wales but not England. On M4, the portion between Junction 29 and Junction 32 added six lanes in 2010.
