Roadworks on A75 bridge at Dunmuir

Maintenance work on the A75 Dunmuir Road Bridge at Castle Douglas is set to begin on Monday 12 September.

Scotland TranServ on behalf of Transport Scotland will carry out joint replacements on this bridge to ‘improve the resilience’ of the structure.

Overnight closures of the A75 will be in place on the bridge from 7pm to 5am on Monday 12 and Tuesday 13 September. Traffic will be diverted locally through Castle Douglas.

In addition to these works on the A75, five overbridges on this route will undergo maintenance works and joint replacements: A75 Howes Overbridge (Closure) – Local diversion will be in place from 7.00pm to 5.00am each night from 14 to 17 September; A75 Violetbank Overbridge (Closure) – Local diversion required from 08.00am to 4.00pm each day from 19 to 22 September; A75 North Street Overbridge (Closure) – Local diversion required from 08.00am to 4.00pm each day from 26 to 30 September

A75 Nivenhill Road Overbridge (Closure) – Local diversion required from 08:00am to 4:00pm each day from 3 to 7 October

A75 Stapleton Road Overbridge works will be carried out using two-way traffic lights from 10 to 18 October each day from 8.00am – 4.00pm

The works to these five overbridges will not directly affect traffic on the A75 trunk road.

Andy Fraser, operating company representative, Scotland TranServ said: “It is essential that we carry out the bridge joint replacements on these structures on the A75 to ensure they are safe and fit for purpose for local residents and motorists.

“We have planned these works in order to minimise disruption to local residents and road users, however I would urge motorists to leave plenty of time for their journeys.”
