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

What we are responsible for

We have a responsibility to reduce the harmful effects of our motorway and trunk road network.

We do this through:

  • the operation and management of our motorway and trunk roads, and,
  • our planning , design and construction procedures for new infrastructure.

How we protect the environment during road projects and works

In carrying out projects and works on our road network we seek to:

  • Identify the main environmental effects and apply mitigation measures to projects and maintenance works. For significant road proposals we produce an Environmental Statement Non-technical Summary. These documents identify the main environmental effects and describe mitigation measures.
  • Conserve and enhance environmental features on our road network. One way we carry out this work is through Environmental Initiatives. Further information about our initiatives is available by selecting ‘Environmental Initiatives’ on the left hand side of this page.
Encouraging best practice

We encourage best practice through:

  • Providing advice and guidance on best practice. Advice and guidance are available on our 'Interim Advice Notes' page found on the left hand side of this page.
  • Undertaking relevant research, examples can be found on our 'Research Reports'  page found on the left hand side of this page.
