Abstract

Transport Scotland is the Agency of the Scottish Government responsible for the delivery and maintenance of the national Trunk Roads.

The Forth Replacement Crossing is the largest transport infrastructure project in Scotland for a generation. It comprises a cable-stayed bridge across the Firth of Forth and associated new and improved road infrastructure. Transport Scotland in association with its consultants developed an innovative sustainability appraisal process for this major project. This is the first Trunk Road scheme in Scotland to undergo such appraisal.

This paper outlines the development of the sustainability appraisal framework used in the assessment process to factor sustainability into the life-cycle of the project from design through construction to operation and beyond. The project sustainability framework includes objectives which cover economic, social, environmental and resource factors. In particular it describes the full assessment process from inception through to setting of 17 objectives and associated targets and indicators via an iterative process to influence the design of the scheme. These objectives cover a range of factors including transport, accessibility, land use, pollution, health, safety, biodiversity and carbon management. The paper describes how objectives focused on reducing the contribution of the scheme to the causes of climate change were addressed and also how climate change adaptation was dealt with. The paper also describes the role of the stakeholder engagement process and the key stages where this has influenced design. The overall merits of the application of the sustainability framework are discussed in relation to the delivery of acceptable solutions.
