A75 Dunragit Bypass Project


Project Summary: 
This project provides a bypass of the village of Dunragit, to the east of Stranraer, through which the A75 runs at present.

The existing A75 has a 40mph speed limit through the Village and also a height restriction in place at the existing Challoch rail overbridge. This overbridge carries the Stranraer-Glasgow railway line over the A75, requiring high sided vehicles to divert from the A75 onto the side road network. The overbridge has been subjected to a number of bridge strikes over the years, causing lengthy diversions and delays to journey times.

The construction of this project will deliver a new 5.3 kilometer stretch of the A75 providing improved overtaking facilities in both the east and westbound directions, routing traffic away from the Village and avoiding the height restriction at the Challoch rail overbridge.

Traffic Management:

From 3rd March 2014, traffic will be diverted onto new sections of road constructed as part of the A75 Dunragit Bypass to enable works to continue on schedule. This will give road users an opportunity to see at first-hand how works have progressed.

To ensure the safety of road users and workers, a temporary 40mph speed limit will be in place and traffic will be managed at some locations using temporary traffic lights to allow alternating one way traffic.

Project benefits

The scheme will:

  • Route traffic away from Dunragit Village, improving safety and air quality for residents;
  • Improve journey times and journey time reliability on the A75, which forms part of the Euro-route between Europe, Scotland and UK, via the ferry terminals at Loch Ryan in Dumfries and Galloway;
  • Improve safety by increasing the number of guaranteed overtaking opportunities in both directions, reducing driver frustration and vehicle platooning;
  • Improving safety for pedestrians and cyclists by providing in places a new shared pedestrian/cycleway;
  • Maintain the asset value of the A75;
  • Mitigate environmental impacts of the works; and
  • Achieve good value for money.


The contract for this project was awarded on 4 March 2013 to RJ McLeod (Contractors) Limited. Completion of the scheme is expected by summer 2014.

Public Exhibition

A Public Exhibition was held in Dunragit Village Hall, Dunragit on 22 August 2006. The exhibition provided an opportunity for the public to comment on the proposed scheme.

Environmental impact:

There are considerable environmental impacts.

  • There are Scheduled Sites, Scheduled Ancient Monuments (SAM), in the vicinity of the works. Historic Scotland has granted permission to undertake the works.
  • Environmental surveys have been undertaken and it has been identified that mitigation measures shall be required for a number of protected species.


The Draft Side Road Orders and the supplementary Compulsory Purchase Order for the proposed scheme were published on 27 June 2008, namely:

Following the formal consultation period, the Made Orders were published on 20 November 2009.
