Project information


We are carrying out essential work on the A14 between junction 33 and junction 44. The work includes:

  • Bridge waterproofing
  • Work to keep the bridge safe
  • Replacing barriers
  • Drainage
  • New signs
  • Resurfacing
  • Road studs (cats' eyes)
  • Clearer road lines
  • Bridge waterproofing

The work here is essential and will help extend the lifespan of the road and make journeys safer for motorists.

Laybys will be closed from J35 to J39 when full carriageway closures are in place

Some of this work is already taking place and will continue in various phases until winter 2022. During the road closures we will be carrying out as much work as possible to help prevent the need for further road closures in the near future. We are working to minimise the disruption to motorists and would like to thank everyone for their patience while this essential work takes place.


Benefits for this scheme include:

  • Work on the bridge which will improve its safety, the road surface and its lifespan.
  • Safety barrier upgrade which will improve safety and prevent cars going onto the wrong side of the road.
  • Resurfacing work which will improve the quality and safety of the road surface, as well as refreshing the road white lines and road studs (cats' eyes).
  • New drainage system which will help prevent flooding and so reduce any road closures when during heavy rain.
