The Saltash Tunnel will be closed overnight for four nights next week while new fibre optic cables are installed.

Between May 22 and 25, single-lane closures will be in place during the day.

The A38 from Carkeel roundabout to the end of the tunnel will be closed from 8pm to 6am.

Work will be lifted for the Bank Holiday weekend before overnight closures resume on Tuesday, May 30 until June 10.
