Cross Tay Link Road

The assessment of the construction and operation effects of the proposed CTLR Project with regards to the use of materials and generation of waste has been undertaken using methodology outlined in Design Manual for Roads and Bridges (DMRB), LA 110: Material assets and waste.

The effects of the proposed CTLR Project in relation to materials during operation have been scoped out given the minimal requirements for materials and generation of waste.

The proposed CTLR Project will require significant volumes of imported construction materials for foundations, road construction, backfill and structures. The proposed CTLR Project also includes significant earthworks, principally from earthwork cut activities for the realignment of the A9, with material placement required for the A9 overbridge abutments and grade separated junction.

As well as the significant earthworks, the proposed CTLR Project requires construction of three box culverts (Bertha Loch Burn, Stormontfield and Broxy Burn) and three key structures (A9 overbridge, River Tay Crossing Bridge and Highfield Green Bridge) .

Current estimates suggest that all excavated materials can be re-used within the proposed CTLR Project. Maximising opportunities to stockpile and re-use suitable material within the proposed CTLR Project (such as landscaping or screening bunds) will reduce the effects from the generation of waste arisings.  No off-site disposal of material from the earthworks is anticipated.

Where the re-use of materials on-site is not possible, options for the re-use of materials off-site (e.g. as restoration soils) will be fully considered by the Contractor in accordance with their approved CEMP and Site Waste Management Plan (SWMP). The Contractor will develop this further when appointed and create a SWMP in consultation with the Council and the Statutory Consultees as required. 

The assessment has concluded that the effects upon materials as a direct result of the proposed CTLR Project is not significant, however suitable mitigation measures have been recommended in accordance with best practice and site waste management.
