The work will improve the northbound side of the Fox Junction, where the A12 meets Oak Road in Rivenhall End. A new traffic island will be installed to protect drivers turning at the junction and the kerb will be re-aligned. The work will also involve replacing the road markings and installing new signs on approach to the junction.
The work will take place overnight during the week between 8pm and 6am, and is due to be completed by Friday 18 December.
Highways England project manager, Steve Cox, said:
Safety is our top priority, and these improvements will help to reduce the number of collisions at the Oak Road junction. The traffic island, along with the refreshed road markings and new kerbings, will help to make the turnings clearer and protect drivers turning into or out of Oak Road. It will be similar to the traffic island already in place on the southbound carriageway.
At the same time we are installing new signs on approach to the junction to help drivers choose the correct turning and avoid turning into the Whitelands private access road, which is around half a mile before the Fox junction.
All the work will be carried out at night to minimise disruption to road users.
Most of the time when work is being carried out, the Oak Road junction with the A12 will be closed and one lane northbound on the A12.
During the overnight closures a clearly signed diversion route will be in place. Drivers seeking to turn into Oak Road will be directed to follow the A12 to junction 23 near Kelvedon where they can join the A12 southbound to Rivenhall End and turn on to Henry Dixon Road on the south side of the junction.
Drivers seeking to join the A12 from Oak Road will be directed to follow Henry Dixon Road, then on to the southbound A12 to junction 22 near Witham, from where they can re-join A12 northbound.
Access to businesses and for local residents will be available throughout the closures, with drivers escorted past the roadworks.
The work is dependent on suitable weather conditions, and dates may be subject to change.
