Published on December 4, 2025

A serious crash on the M3 has caused major traffic disruptions for commuters, with lane closures and long delays stretching onto the M27. The incident occurred northbound between J13 (Chandlers Ford) and J12 (Eastleigh), leaving travelers stuck in heavy traffic for extended periods. According to AA Traffic News, one lane has been closed, creating a queue of vehicles as the situation worsened through the morning rush hour.

The crash’s aftermath has led to severe delays that are affecting not only the M3 but also M27 travelers. With traffic now spilling onto the M27, many commuters and tourists are experiencing frustrating delays, with speeds slowing to a crawl. This article provides the latest updates, the cause of the delays, and tips for those planning to travel through this route.

M3 Traffic Incident Causes Disruption

The traffic incident on the M3 northbound from J13 A335 Leigh Road (Chandlers Ford) to J12 A335 (Eastleigh) led to an immediate lane closure. The AA Traffic News reported that the accident has created queues of traffic that are expected to last for several hours. The crash caused a ripple effect on the surrounding roads, with delays extending onto the M27 as well.

The road blockage and resulting congestion have caused delays for drivers in both directions, especially those trying to head into Chandlers Ford or continue onto Eastleigh. As traffic slowly moves through the area, commuters have found themselves stuck in miles-long traffic jams, with delays reaching 11 minutes on the M27 Westbound, especially between J4 and the M3. Meanwhile, traffic on the M27 Eastbound has seen delays of 12 minutes with speeds reduced to a mere 5 mph.

Impact on Business and Tourism Travel

The delays caused by the M3 crash have far-reaching consequences, not only for daily commuters but also for business travelers and tourists planning to visit the area. For business professionals traveling between Chandlers Ford and Eastleigh, these disruptions could significantly impact important meetings, leading to delays in attendance and missed appointments.

Tourists visiting Eastleigh or heading toward Hampshire or Southampton will also face increased travel times. The M3 serves as an important route for tourists exploring this part of the UK, especially those heading to popular attractions like the New Forest, Hampshire countryside, and nearby cities like Southampton.

For those heading to the airport, delays could affect those traveling to Southampton Airport or connecting to London via the M27 and M3. With these roads heavily congested, it’s vital for tourists to account for the delays and plan extra travel time.

Emergency Response and Road Clearance

Emergency services responded quickly to the incident, with both police and paramedics dispatched to the scene. The North East Ambulance Service confirmed that one individual was taken to the hospital for treatment, though the full details of the crash are still under investigation. In addition, a Hazardous Area Response Team (HART) was called in to manage the situation and ensure the safety of everyone involved.

As the M3 was cleared, efforts to reopen lanes have been underway, but the extent of the damage caused by the crash has led to prolonged delays. Although the lane closure has been addressed, traffic is still sluggish, especially for vehicles approaching the area.

What to Expect for Travelers

Travelers planning to use the M3 or M27 should expect significant delays throughout the day. The queueing traffic remains heavy, and drivers are advised to check real-time traffic updates before setting out. Those traveling during peak hours should consider taking alternative routes to avoid the M3 and M27 altogether. For those in the surrounding area, local roads may be congested as well, as commuters divert to avoid the main highways.

Quick Tips for Travelers

1. Check Traffic Updates: Always check real-time traffic updates from official sources like AA Traffic News or Highways England to stay informed on the latest developments.
2. Consider Alternative Routes: Use alternative routes, such as A335 or A27, if possible, to avoid the congestion caused by the crash.
3. Allow Extra Time: With traffic moving at a slow pace, be sure to allow extra travel time, especially if you are heading to the airport or have appointments in Eastleigh or Southampton.
4. Use Public Transport: If you’re able to, consider using public transport or local train services to bypass the affected areas.
5. Stay Patient: For those stuck in traffic, staying calm and patient is key. Use your car’s amenities (like the air conditioning, water, and entertainment) to make the wait more manageable.
