It was a challenging day Wednesday to travel across a number of the region's major thoroughfares.
In the Magic Valley, a two truck collision resulted in hazardous material being spilled on the eastbound Interstate 84 near Burley, blocking traffic through much of the night.
A portion of Idaho Highway 55 was blocked for more than four hours Wednesday following a two-vehicle crash on Horsehoe Bend Hill. That accident sent three people to the hospital.
Two people were killed Wednesday in a head-on crash on U.S. 20 near Timmerman Hill in Blaine County. One driver died at the scene and the other driver died a short time later at St. Luke's Wood River Medical Center.
Two people were injured Wednesday evening just east of Star, where a vehicle slammed head-on into an Ada County Sheriff's Office vehicle. The collision occurred on State Street. Both drivers were taken to Saint Alphonsus Medical Center in Eagle.
And more than 30 miles of U.S. Highway 12 between White Pass and Washington State Highway 410 were closed for nearly four hours due to mud and rock slides. Mud and tree debris blocked both lanes through much of Wednesday, but the highway was reopened early today.
