Scotland TranServ, working on behalf of Transport Scotland will carry out the £800,000 overnight resurfacing of this section of the A75 from Wednesday until Sunday August 20.
The work is aimed at delivering long-term benefits to address issues with potholes and structural cracking on this section of carriageway.
Jane Maclennan, Scotland TranServ’s assistant engineer said: “This is an important economic artery connecting a number of larger communities across Dumfries and Galloway with the major motorway networks and the region’s ferry terminals.
“We’re investing across the region on behalf of Transport Scotland, to improve the quality of our road network, delivering long-term benefits for commuters, businesses and tourists alike.”
The work to resurface 1.5km of carriageway will begin at 7 pm on the Wednesday with completion 11 days later.
Temporary traffic management will be in place, including:
* Closing the westbound carriageway, with traffic diverted onto contraflow on the eastbound carriageway.
* Access to Collin from the bypass will be closed throughout, with local traffic diverted via the A709 and Roucan Road
* On weekdays the A75/B724 junction will operate as left in, left out only. Traffic travelling eastbound and wishing to use this junction should travel beyond the junction and turn at Carrutherstown via the B725
* At weekends, the A75/B724 junction will also be closed with access via Dumfries (A780, A781, B725 and B724)
Bus passengers should also note that the westbound bus stop on the A75 will be temporarily relocated to the B724 adjacent to the Collin Waste Water Treatment Works entrance.
