15-mile stretch of A12 to close for two months at Marks Tey

The closure, between junctions 19 and 25, is part of a major resurfacing project and will be in place on weeknights only, between 9pm and 5am.

Work will start on August 10 and is not expected to be completed until October.

National Highways, who is carrying out the work on the major route, has said it will take place in phases.

The first phase will close the southbound stretch from junction 25 to 23 between August 10 and September 12.

The second phase will see the northbound carriageway closed from junction 19 to 25 between September 14 and October 10.

A signed diversion route will take drivers on a 23-mile route along the A131 and A120, past Braintree and Little Waltham.

Northbound traffic will exit at junction 19 onto the A131 and rejoin the A12 at junction 25 from the A120.

Southbound travellers will follow the reverse route via the A120 and A131.
