M4 smart motorway upgrade

The first in a series of public information events have been held to keep the community informed on the M4 switch to a smart motorway.

Highways England will begin upgrading the 32-mile stretch of motorway between junction three at Hayes, west London and junction 12 at Theale, Berkshire after the summer.

The aim is to reduce congestion once the work is completed in the spring of 2022.

The first phase of these works will happen at junction eight and nine at Maidenhead in September and is scheduled to be completed in May 2020.

At the same time, work will start on four bridges between junctions seven, eight and nine.

Highways England held information sessions to discuss the scheme in July. Works east of junctions eight and nine will start next spring, so information sessions in Slough will take place in the New Year to ensure information is up to date closer to the works.

Councillor Martin Carter, cabinet member for planning and transport, said: “The work taking place on the M4 may affect those living, working and studying in Slough, as well as once the work has been completed.

“If you think the upgrade may impact journeys you are taking, I highly recommend you attend the information events, so you can familiarise yourself with what this switch means during the works and so you can also become comfortable with how to use a smart motorway.”

Key features of a smart motorway include set speed limits to smooth traffic flows, converting the hard shoulder into an additional lane and the creation of highly visible emergency areas which will be no more than 1.6 miles apart. So if you are driving at 60mph you will pass one approximately once a minute.
