A bus that departed New York City bound for Boston Monday afternoon exploded into flames on the side of a highway but no injuries were reported, authorities said.

The Bolt Bus ignited on the eastbound side of the Massachusetts Turnpike at about 5 p.m., east of the Weston toll booth. The driver noticed smoke, pulled over and evacuated the bus, the company said in a statement.

All 47 passengers retrieved their belongings and were put on another bus, the company said.

The fire was knocked down around 5:15 p.m., but the Newton Fire Department deemed the incident a two-alarm for water supply concerns and to assist the occupants of the bus.

A passenger told NECN that the bus stopped in Connecticut for a mechanical issue, but continued after a mechanic worked on the bus for two hours.
