LEHI, Utah (AP) — A tractor-trailer rig carrying butane was leaking the flammable gas from a leaking tank after overturning on a Utah freeway Saturday, causing evacuations in the area.

The Utah Highway Patrol said the double-trailer rig overturned on northbound Interstate 15 in Lehi and that the freeway was closed in both directions as a precaution pending cleanup.

Lehi is 26 miles south of Salt Lake City.

Assistant City Administrator Cameron Boyle said the area in a quarter-mile around the crash site was evacuated, with residents of an apartment complex relocated to a church building.

Information on cause of the crash wasn’t immediately available.

No injuries were reported.
