Major M1 Crash Closes Key Route: What Travelers Need to Know About Delays and Diversions

Published on December 17, 2025

Emergency services are currently attending the scene of a serious crash on the M1 northbound, between Junction 14 (Milton Keynes) and Junction 15 (Northampton). The incident has caused a significant disruption to traffic, with the motorway now closed to motorists. The closure is expected to last into the early hours of the morning due to the severity of the collision, as emergency responders work to clear the scene.

The closure has left drivers facing significant delays and diversions, particularly as the M1 is one of the key motorways in the UK, connecting London to the Midlands and beyond. Both commuters and tourists planning to travel on this route are being urged to allow extra time for their journeys or to consider alternative routes where possible.

Impact on Traffic: Delays Expected Throughout the Night

The M1 northbound remains closed between Junctions 14 and 15, with significant congestion building up as traffic continues to build up in both directions. National Highways has indicated that the road will likely remain closed into the night, as the nature of the crash requires careful investigation and the removal of vehicles from the scene.

Diversion routes have been established to guide drivers around the closure, but these routes are also expected to experience delays, especially during peak traffic times. Drivers heading towards Milton Keynes or Northampton should anticipate long queues and plan accordingly.

For those unfamiliar with the area, the A509 and A5 are alternative routes, but both are likely to be heavily congested as more motorists divert from the main motorway.

The Role of Emergency Services and Road Recovery

Emergency services, including Northamptonshire Police, have been at the scene since the collision occurred earlier today. The nature of the crash has required a significant response, with firefighters, paramedics, and police officers working together to manage the situation and assist any injured parties.

National Highways has stated that recovery efforts are ongoing, and the closure is expected to last well into the night, depending on how long it takes to clear the crash site. The authorities are urging drivers to exercise caution when approaching the area and to follow diversion signs carefully to avoid further complications.

While it’s unclear at this stage how long the recovery will take, drivers should be prepared for delays well into the early morning hours. The closure has disrupted not only regular commuters but also those traveling for business or tourism purposes.

Diversion Routes: What Drivers Need to Know

Drivers approaching the M1 from the south are advised to take the A509 north towards Wellingborough, which leads back to Junction 15 of the M1. Alternatively, drivers can use the A5 to travel between Milton Keynes and Northampton, though these routes are also expected to be heavily congested.

Motorists should remain patient and follow the official diversion signs posted by National Highways, as roadworks and temporary traffic lights may cause additional delays on these alternative routes.

The Impact on Business Travel and Tourism

The closure of such a major route, especially during the busy holiday season, will have far-reaching consequences for both business travelers and tourists. Commuters traveling for work or meetings in London, Milton Keynes, or Northampton could experience significant delays, affecting both their schedule and productivity.

For tourists traveling to key destinations like Northampton or Milton Keynes, the disruption could lead to missed connections or frustration. As the motorway is a primary route to the Midlands, delays could also affect tourists who are planning to visit London or the surrounding areas.

It’s important for both business travelers and tourists to stay informed about the latest updates on the situation and to monitor official announcements for any changes to road conditions. Checking websites like National Highways or traffic apps can help travelers make informed decisions about their routes.
