M3 Crash Causes Lane Closure and Traffic Delays Impacting M27: What Travelers Need to Know

M3 Crash: Major Traffic Disruptions Impact M27 and Business Travel

A serious crash on the M3 northbound from J13 (A335 Leigh Road – Chandlers Ford) to J12 (A335 – Eastleigh) has caused major traffic disruptions, impacting both commuters and business travelers. The accident, which occurred in early December 2025, led to an immediate lane closure, creating queues of vehicles that worsened through the morning rush hour.

Immediate Traffic Impact

The M3 incident has not only caused delays on its own stretch but also stretched onto the M27. According to AA Traffic News, one lane was closed, causing a queue of traffic that was expected to last for several hours. The crash created a ripple effect, with delays extending onto the M27 as well.

Traveler Experience and Business Impact

The traffic incident has far-reaching consequences, affecting not only daily commuters but also 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 attractions such as the New Forest, Hampshire countryside, and nearby cities like Southampton will also face increased travel times.

The M3 serves as an important route for tourists exploring this part of the UK, especially those headed to airports 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. For business travelers using the M3 and M27 today, it is recommended to check real-time traffic updates before setting out.

Emergency Response and Road Clearance

Emergency services responded quickly to manage the situation. According to reports from the North East Ambulance Service, 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 ensure safety and manage the scene effectively.

While efforts have been made to clear the M3 and reopen lanes, traffic remains sluggish, especially for vehicles approaching the area. Travelers should expect significant delays throughout the day as queues continue to form on both the M27 Westbound (11-minute delays between J4 and the M3) and Eastbound (12-minute delays with speeds reduced to 5 mph).

Advice for Travelers

For those planning to drive on the M3 or M27 today, here are some quick tips to minimize the impact of these ongoing disruptions:

• Check Traffic Updates: Always check real-time traffic updates from official sources like AA Traffic News or Highways England to stay informed.
• Consider Alternative Routes: Use alternative routes such as A335 or A27 if possible, to avoid the congestion caused by the crash.
• 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.
• Use Public Transport: If possible, consider using public transport or local train services to bypass the affected areas and continue your journey with minimal disruption.
• Stay Patient: For those stuck in traffic, staying calm and patient is key. Use your car’s amenities (like air conditioning, water, and entertainment) to make the wait more manageable.

The M3 crash has caused significant disruption across Chandlers Ford, Eastleigh, and the M27 corridor, leaving commuters and tourists stuck in heavy traffic. While emergency teams have cleared the area, the aftereffects continue to be felt throughout the day, impacting business travel and tourism. Travelers need to plan ahead and factor in additional time for travel.
