- Reduce accidents and hence improve safety.
- Improve travel times to and from the ferry terminals at Cairnryan and Stranraer.

Impact on travel
Delays during construction, which will result in long-term safety improvements, improved overtaking opportunities and reduced journey times.
Convoy systems or temporary traffic light systems will be in operation during the construction of the scheme for its entire length.
The environmental impact of the scheme is not anticipated to be significant. Land-take will be minimised to reduce impact upon local farming operations.
