Traffic is set to be slowed along two stretches of the A12 as new average speed cameras are set to be switched on.

The Highways Agency has confirmed schemes at Kelvedon in Essex and at Hughes Corner, on the Essex/Suffolk border, are set to be completed by the end of the month.

Once switched on, the cameras will enforce the existing 70mph limit along these notorious stretches on the dual carriageway in an attempt to improve road safety.

They will not be linked to one another, or to the temporary cameras being used to enforce a 40mph limit in place further along the A12 between East Bergholt and Copdock where resurfacing work is being carried out.

Work along this stretch in Suffolk is due for completion at the end of May, when the cameras will be removed and the 70mph limit reinstated.

There is also a temporary speed limit in place through the roadworks between junctions 11 and 12 (Brook Street at the M25 and Mountnessing) which is monitored by average speed cameras.

This is due to remain in operation until April.
