Project information

Overview

Most of our road network is surfaced with asphalt, also known as tarmac, but some roads are built of concrete. These make up around 400 miles (4%) of England’s motorway and long-distance A-road network.

The surface of concrete roads that were designed between the 1950s and 1970s have an average life span of 50 years. Their surfaces are now reaching the stage where they will need to be repaired or replaced for safety reasons, and to help them be less noisy and better to drive on.

Around half of the old-style concrete roads will either have repairs or will be replaced over a five-year period. We’ll be using innovative techniques and new technology to provide a modern road that will last for decades to come, and which is easier and quicker for us to repair in future.

Find out more about our national concrete roads improvement programme, how we are working to improve the environment and our innovative ways of working.

These repairs aim to reduce noise levels from the A11 and extend the life of the road surface between these junctions.
