The M4 will be closed westbound between junctions 15 and 16 tonight and tomorrow night.

The closure will be in place from 8pm to 6am on both nights while work is carried out on the Wichelstowe southern access road.

The project will create a new access road into Wichelstowe beneath the M4, supporting 4,500 new homes and aiming to reduce congestion.

There are currently 50mph speed restrictions on the M4 near junction 16 which allowed the construction of a new embankment to be safely carried out.

Traffic will soon be diverted onto that embankment to keep the motorway moving while work takes place.
