What Is The Reading M4 Motorway?

A motorway that is an adjoining link between London and South Wales is called M4 motorway. It is an unsigned part of the European route E30. Reading, Cardiff, Swansea and Swindon are few major junctions that are directly viewable an accessible from M4.

Until its termination to the north of Pontarddulais, the M4 keeps running alongside, which travels from London to Bristol, and as it crosses the Severn, it starts following the A48.

There are several special features that are a part of M4. For instance, the east bound carriageway that is based in London has a bus lane that starts from junction three and goes up to the elevation section. This lane had to go under various controversies when they were introduced in Reading.
