DMRB Stage 1 Assessment - Assessment Corridor and Improvement Strategies

The assessment corridor for the scheme is shown below and has been defined by considering existing constraints and potential improvement strategies that would give us opportunities to realign the existing A75 around Springholm and Crocketford, taking account of the design standards set out in the DMRB.

Six improvement strategies have been identified within the assessment corridor and were developed to inform the DMRB Stage 1 Assessment. These strategies vary in proximity to the existing A75 and also tie back into the existing route at various locations.

Five of the improvement strategies bypass Springholm and Crocketford. One improvement strategy follows the existing A75 alignment and passes through Springholm and Crocketford.

The improvement strategies considered are broadly defined and do not represent a single route option. The purpose of these strategies is to identify key constraints that may be affected by a route option developed within the improvement strategy and allows the potential effects to be considered.
