An early morning crash involving four vehicles, including two tractor trailers and a school bus killed two and shut down I-84 in East Hartford early Monday morning.

According to the Connecticut Department Of Transportation, the closure was between Exits 55 and 56, and in the area of Route 2 westbound to I-84. Traffic was heavily affected and reportedly backed up for miles. Also, downtown Hartford traffic was also impacted due to vehicles being diverted through that area.

According to wfsb.com, State Police said they responded to "a report of a fatal crash" just before 5:10 a.m. on Monday morning. The crash reportedly involved a school bus and two tractor trailers. Fortunately, there were no children on the school bus at the time of the crash.

Police held a press conference at 9:30 am Monday morning and are now reporting that two people were killed in the crash, however authorities have been very careful not to release their identity until the next of kin is notified. It is unclear which vehicles were being driven by the two who were killed. The cause of the crash remains under investigation.

According to officials at the East Hartford Fire Department the highway will be closed in the area of Connecticut Boulevard for an extended period of time. State police are expected to be on the scene of the crash until at least the early part of Monday afternoon, therefore police recommended finding alternative routes.
