Work to install two sets of permanent average speed cameras along the A12 will begin on Monday.

Speed cameras are being installed at Hughes Corner, between Stratford St Mary and East Bergholt, and around Kelvedon, in a bid to reduce the number of incidents.

It is hoped that by stopping drivers using excessive speed and cutting accidents, it will lead to fewer delays and congestion.

Work will be carried out overnight between 8pm and 6am, and the Hughes Corner work has been scheduled to tie in with the current resurfacing works along the A12 between junctions 31 and 33.

Martin Oliver, Highways Agency project manager, said: “Safety is top priority for the Highways Agency, and this scheme to install average speed cameras will help to make the road safer for drivers on the A12 at these locations.

“The A12 is a vital route and enforcing the speed limit is part of our commitment to keeping journeys on it safe and reliable for the thousands of drivers who depend on it every day.

“We have worked with our contractors to ensure the disruption is kept to a minimum by planning the works overnight and by combining the Hughes Corner scheme with the resurfacing works.”

Work will begin on Monday for four weeks at Hughes Corner and include lane closures, while work at Kelvedon between Rivenhall End and Easthorpe will start the following week on February 9 and is expected to last six weeks. It will also involve lane and slip road closures.
