A bus fire on Interstate 35 just north of Temple caused massive delays to southbound traffic Wednesday evening.

Emergency crews were called to the scene at mile marker 305 near Berger Road around 6:40 PM. Officials say the bus caught fire near exit 308 in Troy.

45 people above the Zavala Plus charter bus bound for Mexico were safely evacuated. No injuries were reported, but one person was being treated for stress-related symptoms.

Traffic was being diverted to access roads while crews worked to extinguish the flames and tow the vehicle, which is a total loss.

The fire was under investigation Wednesday evening.
