Drivers on the M4 face delays during the first two weekends of December but there will be some respite in the run up to Christmas.

Stretches of the motorway will close for an entire weekend as work continues on the project to transform part of the M4 into a smart motorway.

It is being converted into four running lanes between junction 3 for Hayes and junction 12 for Theale, the stretch between junction 12 and junction 10 at Reading is almost complete but is not fully functioning.

This weekend the motorway will be shut from Friday night through to the early hours of Monday morning between Slough and Maidenhead.
