Essential roadworks are set to bring disruption on the A77 for up to three weeks.
Scotland TranServ will this month begin repairs on the Craigskelly Seawall, south of Girvan.
A single lane closure of the northbound carriageway will take place between Monday, September 23 and Sunday, October 13 .
Alaister Walker, Scotland TranServ’s Senior Structures Technician said: “Scotland TranServ will remove the existing brick structure, and install a new vehicle barrier to protect the safety of our workers during the works.
"We will then construct a soil slope towards the beach side and build a rock armour defence to protect the slope from future erosion.
"The new vehicle barrier will enhance road user safety on completion of the works.
“We have been working in consultation with the local authority, emergency services and key local stakeholders to carefully schedule these works to reduce the impact on the travelling public and complete the project ahead of the harsh wintry conditions which can often make such projects more difficult.”
Temporary traffic lights will be installed on the A77 northbound carriageway during the three week project.
Drivers, particularly those heading to and from the ferry port at Cairnryan, are asked to allow extra time for their journeys.
