Several incidents on the M11 motorway near Stansted Airport have caused significant travel disruption, leading to road closures and substantial delays. Reports indicate a series of collisions, involving at least one car and one van colliding with the central reservation barrier. These events have necessitated lane closures and, in some instances, full motorway shutdowns in both directions.

The M11, a key route serving Stansted Airport and connecting to the M25, has experienced repeated closures. Evidence points to a pattern of accidents occurring in proximity to the airport, impacting northbound and southbound traffic. The severity of these incidents has led to extended clean-up operations and repairs to the motorway's central reservation.

Closure Details: National Highways has provided specific junction numbers and directions (northbound/southbound) affected by the closures, along with updates on lane openings.
Expert Analysis
The recurring nature of these incidents near a major transport hub like Stansted Airport prompts consideration of contributing factors. While reports do not provide direct expert commentary on the specific causes of these M11 collisions, patterns suggest potential issues with:
Traffic Volume: The M11's role as a commuter route and gateway to Stansted Airport likely results in high traffic volumes, increasing the probability of incidents.
Road Design: The repeated involvement of the central reservation barrier may warrant a review of its condition or the factors leading to vehicles impacting it.
Driving Conditions: While not specified for each incident, adverse weather or driver behaviour could be underlying factors in such collisions.
Conclusion
The M11 motorway near Stansted Airport has experienced a series of closures and delays due to multiple, separate collisions. These events, involving vehicles colliding with the central reservation, have significantly impacted traffic flow and travel to the airport. National Highways has been actively managing the closures, facilitating clean-up, and overseeing barrier repairs. The repeated disruptions highlight the M11's vulnerability to significant traffic incidents and their cascading effect on regional travel. Further investigation into the specific causes of each collision may be warranted to identify any systemic issues contributing to these ongoing disruptions.
