Highways England is undertaking resurfacing work on the Northbound carriageway through Junction 19.  This will be done under lane closures where possible, but there will be some overnight (8.00 pm – 6.00 am) closures of each of the slip roads, and the full carriageway.  Please see closure dates and diversion routes (as notified by Highways England to whom any queries should be addressed).  Work is also being undertaken that affects our neighbouring junctions, leading to closures and diversions.
