The works were originally scheduled for March and then rescheduled to July, but concerns had been raised that closing the stretch of road and diverting all traffic onto the A75 during the busy summer period for the ferry port would cause major disruption.
After receiving a number of letters from local residents and businesses raising concerns over the timing of the works, Galloway and West Dumfries MSP Finlay Carson met with Scotland Transerv to request that the works be rescheduled.
The works, now due to take place over the week of September 1 to 8, will involve resurfacing approximately 600m of existing trunk road.
Mr Carson said: “I am delighted that Scotland Transerv have taken on board the legitimate concerns of local residents and businesses and confirmed that the resurfacing works will now take place in September.
“This work is much needed and I’m sure will be welcomed by everybody in the area, particularly those travelling to the ferry terminal.
“I welcome Scotland Transerv’s recognition and acknowledgement of the importance of local events like the Stranraer Oyster Festival when scheduling road maintenance and that to carry out this work during one of the busiest periods for that stretch of road would have caused undue disruption to road users.”
