Motorists could face weeks of misery at a busy Watford roundabout as improvements are made to aid cyclists.

Hertfordshire County Council is installing additional cycle lanes and improving the traffic lights to include a phase for cyclists at the Dome Roundabout.

Traffic lights will be switched off until March 30 and alternative crossing points for pedestrians have been put in place.

In a statement, the council said: “We are currently upgrading the existing signals on the Dome Roundabout as part of our works to improve cycle routes around Watford.

"While the signals are switched off there are alternative crossing points for pedestrians either on St Albans Road near the fire station or by Spring Gardens on the opposite approach.

“There are also alternatives on the A41 at the Asda and Sainsbury’s junction and we have also provided a temporary crossing on the eastern approach to the Dome Roundabout.”
