UPDATE (26/03/21): Due to the forecast adverse weather, maintenance on the A78 between Routenburn and Largs Main Street on Saturday 27th March, Sunday 28th March, and Monday 29th March 2021 has now been postponed. Works will resume on Tuesday 30th March 2021, weather permitting. 


Essential maintenance on the A78 between Routenburn and Largs Main Street will take place from Wednesday 3rd February until Friday 12th February 2021.

This scheme, with a value of £600,000, will benefit around 9,275 vehicles using this route each day by improving the condition of the carriageway and reducing the need for more extensive maintenance in future.

This work will be undertaken on the A78 between the junction of Aubrey Crescent / Douglas Street and Greenock Road the junction between Main Street and Manse Crescent.

On Wednesday 3rd and Thursday 4th February an overnight convoy system will be in operation from Nelson Street south to Manse Crescent.

From Friday 5th to Monday 8th February there will be a full closure of the A78 Main Street from the entrance to the seafront car park to Audrey Crescent / Douglas Street, preventing access to A78 from Brisbane Street, Beachway, and Nelson Street during the closure. A signed diversion route via the A760 Haylie Brae to Greenock via the A737 will be in operation.

From Monday 8th to Friday 12th February, a two-way temporary traffic lights / convoy system will be in operation from 9am to 4pm, each day for the extent of the works.

Diverted northbound traffic will leave the A78 at Haylie Brae / A760 Largs and continue to Kilbirnie to join the southbound B780. From here, vehicles will join the B777 to the A737 at Beith and travel to Johnstone to join the A761. At the Clune Brae (Port Glasgow) traffic will join the A8 from Newark Roundabout and travel west on the A8 to Greenock to re-join the A78 at Bullring Roundabout.

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

Please note, all schemes are weather dependent and may be cancelled or rescheduled if weather conditions are not favourable.
