The agency used quieter surfacing during maintenance works in 2002 on the A21 section from Dibden Lane Overbridge to the A225/B245 interchange at Sevenoaks Weald and on the crawler lane, constructed in 2006, which runs just north of the lay-by near Morleys Lane Interchange to just north of the Gracious Lane Overbridge on the northbound carriageway.
The latest technical surveys for the A21 Sevenoaks Bypass show it is in good condition. Current policy following the 2004 spending review is that roads are only resurfaced when required for maintenance or safety reasons. The Highways Agency therefore has no plans to carry out further resurfacing works on the Sevenoaks section of the A21 with low noise surfacing within its current programme.
When the bypass does require resurfacing in the future, for safety and maintenance reasons, quieter surfacing will be used.
