Urgent M25 repair works near Watford tomorrow are among a series of upcoming motorway lane or road closures over the next fortnight.

A clockwise lane of the M25 will be closed from junction 19 to junction 20 (where it meets the A41) while the urgent technology repairs are carried out, between 10pm on November 20 and 5pm on November 21.

At the same time, works will be taking place in the clockwise M25 between junction 24 and 25, with a lane shut for motorway incident detection and automatic signalling system (Midas) installation, and there will be a lane closure between junction 21 and junction 22 for weather installation works.

Delays are expected at those points, but they are not expected to be more than 10 minutes each.

Some other works later in the two-week period are expected to cause longer delays, including clockwise full closures further along the M25.
