Major maintenance work on the A27 Adur viaduct is due to begin next week.

The scheme, scheduled for completion in mid December, will involve major strengthening on the bridge's steel structure and concrete deck.

The work is to ensure the long-term maintenance and safety of the viaduct, at Shoreham, so it can continue to be used by heavy traffic.

Much of the work will be carried out underneath the structure but there will be about 40 overnight closures between the junctions with Coombes Road and the A283.

Advance notification will be given for each of the full closures.

There will also be some lane closures between 10am and 4pm.

During the rush hour, two lanes will be open in both directions on the A27.

The work is due to start on Monday.
