A12 to shut at night for the whole weekend as improvement works …

Motorists could face long delays on the A12 this weekend due to ongoing planned weekend closures that are expected to continue this week. The closure is set to happen on the northbound carriageway between Junction 25 (Marks Tey) and 26 (Stanway), which will start from 9pm tonight to 5am August 14.

The closures are part of the reconstruction of the A12, which started October 2022. The project involves removing concrete road surfaces and some foundations before rebuilding and resurfacing the road.

According to National Highway, the schedule is at the halfway stage. The closure and diversion routes have been altered as reconstruction is happening around the entrance slip road of Junction 25.

Diversion routes have been confirmed during the closures but motorists are still warned about possible delays. Some local councils have also published posts alerting motorists about the closure.

In a Facebook post, Kelvedon Parish Council wrote: "Please be aware that the next full weekend closure of the A12 northbound will be happening this weekend. They will be closing sections of the A12 northbound between junction 25 and 26 from 9pm on Friday 11 August until 5am on Monday 14 August."
