Traffic is gridlocked on the main way out of two major business parks in Watford.

A lane closure in Ascot Road has left motorists leaving Watford Business Park and Croxley Green Business Park facing frustrating delays.

The roadworks are positioned outside Action for Children and are set to last until next Sunday.

The road is the only way out of the two business parks.

Traffic is tailing back around the one-way system in Caxton Way and cars are queuing as far back as the Royal Mail delivery office.

The work is being done by the City of London Telecommunications (COLT).
