You can more details about the maintenance schemes taking place in the South East below:

The M3 junction 7 needs emergency carriageway repairs to be carried out at short notice. This will require closing the M3 at junction 7 from 9pm on Friday 5 February until 6am on Monday 8 February 2021.

The closure at junction 7 of the M3 will be a full weekend closure in both directions. It will require all traffic in both directions to come off the M3 at the junction 7 exit slip road and to re-join at the junction 7 entry slip road should they wish to continue on the M3. There will be a reduced speed limit approaching junction 7 from both directions.

We are carrying out urgent safety maintenance work on a section of the A21 near Tonbridge in Kent. The existing subway at Manor Farm will be completely rebuilt and part of the Medway Viaduct will be repaired. As a result the A21 between Morley's Roundabout and Tonbridge will be closed for 10 full days. This closure is scheduled from 8pm on Friday 14 February to 6am on Monday 24 February.


A21 diversion routes


If you are travelling southbound on the A21, you will be diverted at the Sevenoaks Weal Interchange.

Take the second exit to follow the B245 (Hildenborough) to the A227 southbound.

Then take the second left along Bordyke Road/Hadlow Road.

From there, follow Cannon Lane/A26 and re-join the A21 southbound at the Vauxhall Lane Interchange.


If you are travelling northbound on the A21, you will be diverted at the Vauxhall Lane Interchange.

At the following roundabout, take the third exit onto the A26.

Turn left to join Hadlow Road/Bordyke Road, then turn right to join the A227/B245

Follow the B245 until Sevenoaks Weald and merge onto the A21 northbound via the third exit.

We’re carrying out work to improve the embankment’s stability along the A21 from Seven Oaks bypass at Westerham Road to Morley’s Roundabout on the southbound carriageway

This will involve installing soil nails to the slope and carrying out some vegetation clearance, replacement fencing, installing new drainage and planting new vegetation.

This work will means we’ll need to reduce the A21 from the Sevenoaks bypass at Westerham Road to Morley’s roundabout down to one open lane with a 50mph speed limit during the day and night for the duration of the works.  There will be free recovery in place.

The A21 carriageway from Seven Oaks bypass at Westerham Road to Morleys roundabout will be closed from Saturday 20 February for two nights between 9.00pm and 6.00am the next morning in order to install the traffic management.

Diversion route

At the A25 junction, southbound traffic will be diverted off the A21 and onto the A25 Westerham Road eastbound. At Riverhead, traffic will be diverted south onto A224 London Road and onto A225 Tonbridge to Morleys roundabout.

A21 Kippington to Dibden Lane diversion

There will also be further overnight closures for:

  • positioning plant and equipment
  • removing traffic management

We will provide further details nearer to the time for these works.
