A9 Dualling - Pass of Birnam to Tay Crossing - Design Manual for Roads and Bridges (DMRB) Stage 2 Scheme Assessment Report
The Design Manual for Roads and Bridges (DMRB) Stage 2 assessment identified route options taking account of constraints, potential environmental, engineering, and traffic and economic effects and considering feedback from the pubic and other stakeholders. These options were assessed, identifying the environmental, engineering, and traffic and economic advantages, disadvantages and constraints associated with each route option. The Preferred Route Option, which was announced on 20 December 2023, was then identified taking account of these assessments.
The Design Manual for Roads and Bridges (DMRB) Stage 2 Scheme Assessment Report sets out the route option development and assessment process, including the identification of the Preferred Route Option, which will be taken forward for further development and refinement as part of the DMRB Stage 3 assessment.
