Work to improve signage for customers, providing a more efficient reminder that DartCharge payments are due.

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 are carrying out work to enhance the drainage of the M3 northbound carriageway at junction 6. The work includes creating a longer drainage channel in the central reservation, adding drainage outlets and adjusting the gradient of the road surface.

To carry this work out safely whilst keeping overall disruption to a minimum, we will have lane closures in place on both the northbound and southbound carriageways overnight 9pm to 6am from Monday 11 January to Friday 29 January 2020 (Monday to Friday only).

We will be closing the M3 northbound carriageway between the exit and entry slip roads at junction 6, from 9pm on Friday 22 January to 6am on Monday 25 January 2021. The fast lane of the M3 southbound carriageway will also be closed in the area for the safety of our workforce.

During the weekend closure, traffic will be diverted off the M3 via the northern exit slip road, across the roundabout to re-join the M3 via the northbound entry slip road. Road users are advised to plan ahead and allow extra time for their journeys. Road users on the M3 heading to or from the Basingstoke area are advised to use either junction 5 or junction 7 during the closure.
