Planning around M1 roadworks
Major M1 works — including smart-motorway upgrades and resurfacing — often run overnight, when lanes or whole sections may be closed and diversions put in place. Where you can, check the affected junctions, allow extra time, or plan an alternative route. For live updates across the whole motorway see our Latest M1 Traffic News page, and use the M1 junction map to find your junction.
