Planned roadworks on the A78 at Wemyss Bay will lead to a full weekend closure and a diversion between Largs and Greenock.

Essential maintenance on the A78 between The Lighthouses and Kelly Burn will take place from 8pm on Friday November 20 to 6am on Monday November 23.

The £180,000 scheme will improve the condition of the carriageway and reduce the need for more extensive maintenance in future.

Northbound traffic will be directed to leave the A78 at Hailie Brae in Largs and continue on the A760 to Kilbirnie to join the southbound B780.

From there, vehicles will join the B777 on to the A737 at Beith and continue north to the A737 towards Johnstone and join the A761 to Clune Brae in Port Glasgow.

Traffic will then follow the A8 at Newark Roundabout and travel west to Greenock, to re-join the A78 at Bullring Roundabout.

Southbound traffic will follow the same diversion in the opposite direction.
