Overnight M1 roadworks planned through Northamptonshire during 2026
Motorists using the M1 through Northamptonshire are being warned to expect regular overnight closures throughout 2026 as part of a major programme of maintenance and improvement works announced by National Highways.
A temporary traffic regulation order has been made covering the M1 between junctions 15 and 30, affecting stretches of the motorway in West Northamptonshire and North Northamptonshire, as well as parts of Leicestershire, Nottinghamshire and Derbyshire.
The works are due to take place as required overnight between 7pm and 6am, extending to 7am on Saturday and Sunday mornings, during a period beginning on January 2, 2026, and running until December 23, 2026.
Under the order, closures may be imposed on both the northbound carriageway between junctions 15 and 30 and the southbound carriageway between junctions 30 and 15. Restrictions may also affect associated slip roads and link roads, the circulatory carriageway at M1 Junction 21, connecting the M69 and A5460, and a section of Waterloo Lane at Trowell, including the bridge over the M1.
Emergency refuge areas adjacent to the affected motorway sections may also be closed when works are taking place.
National Highways said the timing and length of individual closures will vary, depending on the nature of the work being carried out. During closures, traffic will be diverted via alternative M1 junctions and surrounding local roads, with signed diversion routes in place.
The restrictions will not apply to emergency services, works vehicles, winter maintenance or traffic officer vehicles, and will only be enforced when clearly indicated by traffic signs.
The order comes into force on December 29, 2025, and will remain in place until December 23, 2026. Drivers are advised to plan ahead, allow extra time for overnight journeys and check travel information before setting off.
