CALDWELL - A Kuna man is dead after a semi-truck carrying two flatbed trailers drove off Interstate 84 in Canyon County around 5:30 a.m. Tuesday.

Idaho State Police say 66-year-old Donald Pasma was westbound on I-84 when for unknown reasons he drove off the left shoulder at milepost 16, about one mile west of Sand Hollow Road. The truck went through the median, over an overpass for a small farm road and crashed into a retaining wall. Pasma was pronounced dead at the scene.

Idaho State Police, Canyon County and Payette County Sheriff's deputies responded to the crash along with Payette, Middleton and Caldwell fire departments.

The left lane on westbound I-84 at the crash site is still blocked while the vehicles are being removed by a tow truck.

Idaho Transportation Department is assisting with traffic control.   

The crash is still under investigation by Idaho State Police and a crash reconstruction team.
