A14 junctions 38 - 42 maintenance works
We're maintaining the A14 between junctions 38 (Kentford) and 42 (Bury St Edmunds) from Spring to Summer 2026. Works include resurfacing, refreshing road markings and replacing cat's eyes.
Closures and diversions
Due to recent record high temperatures, road surfaces sometimes take longer to cool and cure.
With cooler temperatures now forecast, we'll return to complete our work on the A14 between Kentford and Bury St Edmunds.

Background
The A14 is a vital route connecting Felixstowe port to the North, Midlands and East of England, carrying local, regional and international traffic.
While we know closures are disruptive, this essential maintenance will extend the life of the road and reduce the need for more significant works in the future.
