The bus involved was an Adirondack Trailways bus, which had left upstate New York and was heading toward New York City.

News 12 spoke with a woman whose mother was a passenger on the bus. Kasey Mallette says that her mother Marla was sitting in the back of the bus when it felt like the bus hit something. Mallette says that her mother thought that the bus was going to overturn. The mother was taken to hospital to be checked out, but was expected to be OK.

 

Parts of the highway were closed for a time following the crash, leading to a major traffic delay in the area.

The cause of the crash is under investigation.
