SALT LAKE CITY — Interstate 80 was closed in both directions in western Utah for hours after a semitrailer hit a military vehicle in the road, part of a fiery chain-reaction crash that left two dead near the Nevada border.

The Utah Highway Patrol says a semi hauling a military vehicle east crashed early Wednesday morning on a curve in the highway outside Tooele, about 40 miles west of Salt Lake City.

The crash tossed the military vehicle into the westbound lanes, where a FedEx truck collided with it.

The driver of the military-hauling semi died, as did a passenger in the FedEx truck. The FedEx driver was also hurt.

Traffic was diverted off the highway, leading to long hours-long delays in the area about 100 miles from West Wendover, Nevada.
