Overnight lane closures will be enforced on a busy road for three weeks so improved signs can be fitted.

The Highways Agency wants to make improvements on the coast bound stretch of the A21 near the Morleys interchange and junction with Quarry Hill.

It will also close the London bound exit slip road at the Morley’s interchange.

They will be enforced between 8pm and 6am from Monday, June 30.

A signed diversion will be in place.
