Norwich, CT (April 21, 2026) – A serious vehicle crash led to a full shutdown of Interstate 395 northbound near Exit 18 in the Occum/Route 97 area.
The crash was reported on Monday, April 21, shortly before 10:45 a.m. Emergency units arrived to find a vehicle collision involving at least one seriously injured person. A medical helicopter was initially requested to assist with transport due to the severity of the injuries.
Officials later arranged for ground transport to a nearby hospital after initial coordination on scene. A trauma alert was also issued in preparation for the patient’s arrival.
Both northbound and southbound lanes of I-395 were temporarily closed to allow emergency response operations, including space for the helicopter to land. Southbound traffic was later reopened, while northbound lanes remained closed for an extended period as crews worked to clear the wreckage and investigate the scene.
Traffic was diverted off the highway at a nearby exit while cleanup and recovery efforts continued. No additional injuries have been confirmed at this time.
Authorities continue to investigate the cause of the crash, and more details will be released as soon as they become available. Our thoughts are with those affected as they continue to recover.
What Happens When a Serious Injury Crash Closes a Highway Corridor?
When a serious crash occurs on a major highway, traffic is often shut down in one or both directions to create a safe working area for emergency units. This allows responders to access injured people, manage hazards, and prevent secondary collisions from approaching traffic.
In situations involving severe injuries, medical helicopters may be requested for rapid transport, especially if ground access is delayed or the condition is time-sensitive. However, ground transport can still be used depending on the on-scene assessment.
Highway closures can also be extended when investigators examine the crash site. This process often includes documenting vehicle positions, roadway conditions, and any physical evidence before reopening lanes to traffic.
