Passengers who were unhurt were put on another bus and continued their journey, authorities said.
The coach bus was from Toronto-based AVM Max 2000 Charter Services Inc., state police said. The phone for AVM Max rang unanswered Saturday afternoon, and the company did not respond to an email Saturday.
The crash was the latest of several coach bus accidents over the past few years on American highways. Last year, a bus carrying gamblers from a trip to a Connecticut casino struck a guardrail as it entered New York City, then toppled over and hit a signpost that sliced off the top of the bus. Thirteen people were killed. A manslaughter trial for the driver began last month.
Saturday's accident backed up traffic in the area for hours while law enforcement officials and emergency services vehicles attended to the scene. Several highways connect there, and the area is known locally as the "spaghetti bowl," according to The Record.
