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 extensive concrete repairs to the bridge which carries the A34 over Godstow Road, near Wytham in Oxfordshire. Works will also involve replacing the bridge parapet, strengthening the safety barrier and replacing the bridge joints.

We will be carrying out the repairs during both day and night-time hours. You may see no activity along the A34 whilst works are taking place beneath the bridge.

Narrow lanes and a 50mph speed restriction will be in place on the A34 for the duration of the work for the safety of both our workforce and customers.

Temporary traffic lights and a reduced speed limit of 30mph will be in place along Godstow Road beneath the bridge (this is due to specialist scaffolding being in place).

Access for pedestrians via the footpath will be maintained during the works.

We are installing a new noise barrier along the M27 westbound carriageway at Port Solent, starting from the bridge at junction 12 to the bridge which carries the M27 over the railway line near Paulsgrove.

The barrier will help further reduce noise levels from this section of the M27 which we have already resurfaced so it is less noisy.

At the same time as we install the new noise barrier we will also be replacing the bridge joint on the Cosham Link at junction 12 of the M27. This will involve removing the central reservation and installing a new joint.

There will be daytime and overnight lane closures, overnight slip road closures and full overnight road closures at different points throughout all this work. There is also a 40-mph speed limit in place on the Cosham Link at junction 12. This is necessary because we are removing the central reservation.

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