Temporary traffic lights are causing delays on the morning commute.

Drivers reported long queues and 15-minute delays at the four-way lights at the junction of Kings Langley High Street, Vicarage Lane and The Nap this morning.

UK Power Networks are reportedly conducting electrical works until March 6.

Motorists who regularly rely on this route to and from work are advised to allow more travel time, or to find an alternative journey.
