A serious crash on the M11 motorway in Essex has led to substantial traffic delays for travelers, especially those heading to Stansted Airport. The incident occurred on Sunday morning at 8:11 AM, prompting lane closures between Junction 8 (Stansted Airport) and Junction 9 (Newmarket). Currently, one lane remains closed in both directions as emergency barrier repairs are underway. National Highways has indicated that drivers are facing delays of approximately 30 minutes and congestion extending for about 3 miles. The AA Route Planner has reported heavy traffic not only on the M11 but also in nearby areas such as Elsenham, Newport, and Great Chesterford, where slow-moving traffic is evident. Motorway cameras confirm the extent of the delays, with multiple warning symbols indicating ongoing roadworks or incidents contributing to the congestion. Authorities expect the lane closures to remain in effect for most of the day, impacting many travelers during a busy weekend.
