The roughly eight-hour full closure of I-15 following a collision between Montana City and Clancy Monday “was due to the complexity of the incident scene” and hazardous conditions caused by a leaking fuel trailer that rolled onto its side, according to Doug Dodge of Jefferson County Disaster and Emergency Services.
The collision, reported at 8:21 a.m., involved a car and a semi truck towing two trailers filled with fuel. According to Griffin Sutherland of the Montana Highway Patrol, the driver of the northbound car lost control, crossed the center median, collided with the southbound truck, came to a stop and caught fire.
The impact caused the truck to cross the center median into the northbound lane, where the second trailer detached and rolled onto the road surface before the truck and first trailer came to a stop near the frontage road, Sutherland said.
