HEYBURN — A truck hauling a semitrailer crashed through the railing of the overpass at exit 211 near Heyburn about 6:30 a.m. Monday, landing on a car on Idaho 24 below.

Police say the semi driver died at the scene but have not released a name pending notification of next of kin.

The semi landed on the state highway, hitting a 1997 GMC pickup driven by Gregory Grove, 63, of Albion.

Police said Grove was not taken to a hospital.

Gray smoke billowed into the sky as firefighters doused water on the crash. The crash took out a chunk of the westbound railing of the Interstate-84 overpass at Exit 211.

All four lanes of traffic on the highway were blocked shortly after the crash. The westbound lanes on I-84 are reduced to one lane.

Police did not know whether either driver wore a seat belt.

This crash is under investigation by the Idaho State Police.
