Two lanes along Interstate 41 in Oshkosh were closed Tuesday night after emergency crews responded to a report of a bus fire just before 8 p.m.
Reports indicate that the bus was carrying students from Neenah High School back from a trip to Great America before it caught fire.
The school said the bus was carrying 39 students and two chaperones, however there were no injuries and another bus was able to bring them back to the school.
Investigations showed that the fire was caused from a flat tire. The bus also started leaking fuel, causing the need for Hazmat to arrive on scene.
