A75 East of Mossyard | Road Improvement Scheme: Final Phase

Amey, on behalf of Transport Scotland, will commence the final phase of overnight resurfacing works on the A75 east of Mossyard from Tuesday 22 April to Thursday 8 May 2025, as part of a wider investment of around £1million to improve infrastructure on this section of the south-west trunk road network. Arrangements for resident and local business travel through the works will be in operation. 

These vital works mark the completion of a two-phase programme first initiated in 2024 and will significantly enhance road safety, improve long-term durability, and reduce the need for future disruption. The scheme will also deliver important environmental benefits using innovative ex-situ recycling techniques, which will prevent over 1,000 tonnes of tar-bound material from going to landfill. 

Resurfacing will be carried out overnight to minimise disruption, with full road closures in place between 8pm and 6am, and daytime Temporary Traffic Lights (TTLs) operating while the road is cooling. The daytime TTLs will also ensure the safety of road users passing through the extents of the scheme. 
The programme of overnight works will operate on the following dates: 

• Tuesday 22nd April – Thursday 1st May between the hours of 8pm and 6am each night. 
• Friday 2nd May and Saturday 3rd May between the hours of 10pm and 6am each night. 
• Monday 5th May – Wednesday 7th May between the hours of 8pm and 6am each night.

There will be no overnight work on Sunday 4th May and daytime temporary traffic lights will also be in operation between Tuesday 22nd April and Friday 2nd May. All traffic management will be removed by 6am on Thursday 8th May 2025.  

Due to the depth of treatment and required road widths to safely deliver these works, total road closures are the only viable way to undertake this project to ensure the safety of our roadworkers, the travelling public, and the site. Overnight closures have been chosen to reduce disruption at peak travel times and when traffic volumes are lower. 

While these night-time closures are in place, a signed diversion route will be in operation. 
Southbound traffic will leave the A75 at Castle Douglas, take the A713 north to Ayr and the first exit at Bankfield Roundabout on to the southbound A77. They will then continue to Girvan to take the second exit at Shallochpark Roundabout on to the A714 and re-join the A75 at Newton Stewart. Northbound traffic will follow the route in reverse. 

Access for residents and local businesses, including caravan park guests, remains a key priority, with local access arrangements in operation throughout the works. Additional measures, such as dedicated shuttle services and special arrangements for key events, have also been made to minimise inconvenience. 
Access for emergency service vehicles will be maintained throughout these works, under escort. 

Recognising the importance of the local tourism economy, particularly during the spring and summer seasons, the timing of the works has been carefully considered in consultation with operational stakeholders, including the local authority, emergency services and bus operators. The schedule avoids the Easter holidays and has been planned to take advantage of the warmer weather required for the specialist materials being used, conditions which are critical for the success of this environmentally responsible resurfacing method. 

Brian Park, Operating Company Representative for Amey, said: “We understand the concerns raised by local businesses and residents, and we’re grateful for their ongoing patience. While these works are essential, we’ve taken every possible step to reduce the impact by coordinating access, enhancing communications, and delivering the project in a more sustainable way. When complete, this section of the A75 will offer a smoother, safer and more resilient route for all road users.” 

The project has already seen the successful completion of the first phase, with only this final stretch remaining. The upgraded carriageway will significantly reduce the need for reactive repairs and extend the road’s lifespan, delivering long-term benefits for the region.
