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.
