All northbound lanes were closed at Exit 89 in Havre de Grace in Harford County at around 3:40 p.m. after the bus apparently blew a tire and hit a guardrail. The vehicle remained upright.
A passenger told Eyewitness News that first the bus hit an overhang, shattering windows.
There were 74 passengers on board. Firefighters helped them all get off the bus, and no one was seriously hurt.
Another bus was brought in to finish the trip.
