Drivers are facing delays on a busy route to a city airport due to a nine-mile diversion on the A140.

The A140 Cromer Road in Hellesdon, near Norwich Airport is set to close for several days of roadworks, costing the Norfolk County Council £83,234.

The closure on June 7, June 10, June 11 and June 12 between 9.30pm and 3.30pm will prevent people from parking on the Cromer Road and Mayfield Avenue junction to the northern Norwich Airport Park and Ride entrance.

A road rejuvenator will be sprayed on to the road surface to extend the life of the road and requires time to soak into the top layer.

A nine-mile northbound diversion route follows the A1042 Mile Cross Lane, A1042 Chartwell Road, A1151 Wroxham Road, A1270 Broadland Northway on to the A140 Cromer Road.

Southbound traffic will be open for the duration of the works.

Vehicle and pedestrian access to properties will be maintained, although delays may be possible.
