Environmental Impact Assessment Report - Pass of Birnam to Tay Crossing - A9 Dualling
An Environmental Impact Assessment (EIA) for the proposed scheme is required under European and Scottish Legislation. The EIA Report details the findings of the EIA, which has been undertaken in line with the Design Manual for Roads and Bridges (DMRB). The purpose of the EIA is to investigate the likely effects of the proposed scheme on the environment, people, communities and businesses. The Environmental Impact Assessment Report (EIAR) for the A9 Dualling Pass of Birnam to Tay Crossing project was published on 30 May 2025.
The Statutory Consultation Period closes on 25 July 2025.
Any person wishing to make any representations about the project and the Environmental Impact Assessment Report may do so in writing to the Director of Major Projects, Transport Scotland, 177 Bothwell Street, Glasgow, G2 7ER, or by email to a9dualling@transport.gov.scot. Any such representations must be received on or before 25 July 2025.
A privacy notice in relation to how any personal data collected from a representation may be used can be viewed or a copy in writing can be obtained from A9Dualling@transport.gov.scot or Transport Scotland, 177 Bothwell Street, Glasgow, G2 7ER.
