(KSL News) -- A semi-truck rolled over this afternoon, spilling a toxic chemical and shutting down three ramps linking I-15 with I-215.

Hazardous materials crews are evaluating and cleaning up sodium hydroxide. The truck was on the ramp connecting westbound I-215 with southbound I-15 when it rolled on a curve.
Sodium hydroxide is very corrosive and Utah Highway Patrol is keeping everyone at least 150 feet away from as a precaution, but there have been no evacuations.
Sgt. Ted Tingey,Utah Highway Patrol: "Right now our main concern, it is sodium hydroxide, we do suspect too that we do have a few other chemicals mixed in there or they're in their own individual plastic containers, we don't know what has ruptured what has mixed, that's what we're waiting for, for hazmat to go down there and assess the situation."

UHP says the drivers of the truck are a father and son from Florida. Both were treated at the scene.
Three of the eight ramps connecting the two roads were closed, including I-15 south to I-215 both east and west and the ramp where the crash happened I-215 west to I-15 south. The roads were expected to reopen early Sunday.
