PHOTOS: Northbound traffic on I-19 was restricted north of Green Valley because of a truck fire and the ensuing cleanup on Wednesday night, Jan. 8. According to Green Valley Fire District, the fire happened around 11:00 p.m. The tractor-trailer was loaded with pallets of tomatoes and when crews found the truck, the flames were beginning to burn the trailer. The crews quickly extinguished the fire and removed smoldering debris. The driver was unharmed and no other injuries were reported. The freeway was limited to one lane well into Thursday morning as the truck was unloaded and the roadway was cleared.
