Drivers in Watford, Garston, and Bushey are being warned of disruption over the next three weekends.

Closures will be in force on the A41 Colne Way because of repairs being carried out on the River Colne Bridge that runs over Otterspool Lane.

The work will begin this Friday night (June 17) and run for three consecutive weekends.
