MESSAGE FROM NATIONAL HIGHWAYS:

National Highways will be carrying out repairs to the southbound section of Birchwood Road Bridge, which crosses the A12. These essential repairs will help ensure the bridge remains safe and reliable for many years to come.

The work is planned to take place over three weeks, from Monday 7 September to Monday 28 September 2026. They will work overnight between 9pm and 5am, with some traffic management measures remaining in place during the day and at weekends. Please note that dates may change due to adverse weather or unforeseen circumstances.

They'll do everything they can to keep disruption to a minimum and complete the repairs as quickly and safely as possible.

Closures and diversions

To carry out the repairs safely, the following closures will be required:

• Full southbound closures on the A12 between junctions 33 (Copdock Interchange) and junctions 29 (Ardleigh Crown Interchange).
• Lane closures on both the A12 southbound and northbound carriageways.
• Full closures on Birchwood Road in both directions.
• Temporary traffic lights on Birchwood Road.

The main A12 southbound diversion is longer than usual to provide a suitable route for all vehicle types. To help maintain safety along the diversion route, they will implement anti-speeding measures and install temporary message signs.

More information about closures and the diversions.

Emergency vehicles will have access through the roadworks
