Road Closure Information

Essex and Suffolk Water will need to divert two of their water mains.  National Highways plan to help them with this by installing part of the infrastructure required for the water mains diversion across the A12 near Margaretting.

To do this safely, they will need a full closure of the northbound carriageway between junctions 12 (Brentwood) and 15 (Three Mile Hill/Webb’s Farm Interchange). This will take place from 9pm on Friday 5 April to 5am on Monday 8 April 2024.

A clearly signed diversion route will be in place.

Please note that the southbound carriageway will remain open during this period.
