Crews Responding to Tour Bus Fire on I-95

Miami Fire Rescue is responding to a large bus fire on I-95 near the 62nd Street exit in Miami, officials with the City of Miami said. 

Video shows clouds of smoke spiraling out of the bus as passing cars drive by. Officials say 59 people were on the bus at the time of the incident.

The bus pulled over after passengers told the driver they smelled smoke in the air. By that time, the fire had spread, leading to the evacuation of all passengers.

Two passengers were evaluated by paramedics after they reported difficulties with breathing. No injuries were reported and all passengers were placed on another bus en route to the Port of Miami.

It is unclear what sparked the flames. Crews are investigating the cause of the fire and the express lane of southbound I-95 is currently closed. 

This is a developing story and will be updated.
