Work to upgrade a 32-mile stretch of motorway has begun, with disruption expected until 2020.

The stretch of the M4 between junction 3 at Hayes, west London, and junction 12 at Theale is being converted to smart motorway by Highways England and work has started between junctions eight and nine in Maidenhead.

Slough Borough Council has taken to social media to raise awareness of the possible disruption coming to the roads, saying: “The 32-mile stretch of motorway between junction 3 at Hayes, west London and junction 12 at Theale, Berkshire, is being upgraded by @HighwaysSEAST.

“The work is scheduled to be completed in May 2020.”

Slough Borough Council also shared a link to a newsletter produced by Highways England, which states that closures are planned, but that disruption is hoped to be kept to a minimum.

It states: “Full carriageway closures on the motorway will be taking

place overnight throughout the project.

“The key aim remains to keep three lanes open during the

peak travel times. The best way to view the various

closures is through the Traffic England website.”
