The Scottish Government continues to invest in the safe and efficient operation of the A77. Planned improvements for 2023 include slope stability works at Glengall, the upgrade of a number of existing lay-bys, upgrades of the Whitletts and Dutch House roundabouts and improvements to existing drainage at Cairnyan.

Since 2007, the Scottish Government has invested approximately £64 million in five separate road schemes on the A77, including the recent completion of the £29 million Maybole bypass, which opened in January 2022.

The A70 is a local authority road.
