A road in south Wales
We look after 75 miles of motorway and over 1000 miles of trunk road in Wales.

We work closely with local government and other bodies to improve and maintain roads throughout Wales.

We are responsible for:

  • constructing new roads and improving existing ones
  • renewing roads, bridges and other structures
  • the day to day maintenance, including winter maintenance.

Many transport projects and improvement schemes are carried out through the employment of consulting engineers, agent authorities and contractors.

We also look at the environmental impact of transport projects and monitor them carefully as we have a responsibility to safeguard the environment and its biodiversity.
