Drivers travelling on the A14 through Northamptonshire are being warned of regular overnight road 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 sections of the A14 between Catthorpe and Thrapston, affecting parts of West Northamptonshire and North Northamptonshire, as well as neighbouring Leicestershire.

The works are scheduled 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 the A14 eastbound from the M6 junction at Catthorpe to Junction 13 at Thrapston, as well as the westbound carriageway from Junction 13 back to the M6. The restrictions may also apply to associated slip roads, link roads, dedicated lanes, lay-bys, bus stop areas and service roads along the affected stretch.

National Highways said the duration and frequency of individual closures will vary, depending on the type of work being carried out on each occasion. Signed diversion routes will be in place during closures, directing traffic via alternative A14 junctions and surrounding local roads.

The restrictions will not apply to emergency services, works vehicles or winter maintenance 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. Motorists are advised to plan ahead and allow extra time when travelling overnight along the route.
