The improvement and ongoing maintenance of roads can have positive and negative effects on the environment.

We are responsible for managing the effects of our motorway and trunk road network on the environment, while ensuring safety is the primary concern.

We do this through:

  • identifying and assessing the environmental effects of our projects
  • providing measures to reduce negative effects
  • conserving and where possible enhancing the environmental features on our road network.

All our projects are compliant with UK and EU legislation, and use the Design Manual for Roads and Bridges (external link) to help us design roads while keeping the effects on the environment in mind.
