There’s never a good time to complete this type of work on a busy junction such as this, and it is expected that there will be some delays due to traffic in the area during the closures. Please plan extra time into your journeys.

If National Highways are unable to finish the work as planned, there will be additional closures at the end of April to get the work completed. Keep an eye on Twitter (@HighwaysSEAST) or alternatively, please visit the project webpage where more information will be shared.
