A tunnel near the A27 is set to close overnight.

The Cuilfail Tunnel on the A26 in Lewes will close on June 7 from 8pm until 6am.

East Sussex Highways said this is for routine maintenance work.

A diversion will be in place via A27, Brighton Road, High Street, Market Street, Little East Street, and Phoenix Causeway.

A spokesman for the East Sussex Highways team said: "We are very sorry for any inconvenience caused."

The name of the tunnel, which opened in 1980, comes from the Cuilfail area of Lewes.

It is a single-carriageway tunnel through the chalk hillside leading to the A27.

The closure comes at the same time as the full weekend A27 closure in Lancing.

This will start at 9pm on June 7 and will end at 6am on June 10. 

It is the fourth full weekend closure to take place on the busy A-road, which is currently having a new roundabout built for the New Monks Farm housing development.
