The Idaho Transportation Department has reopened all lanes of Interstate 84 between Mountain Home and Boise to traffic. Westbound lanes were reopened shortly after noon, and the ITD opened eastbound lanes around 1:45 p.m.
Westbound lanes of I-84 between Mountain Home and Bliss opened back up shortly after 4 p.m. Traffic is now moving throughout the entire Twin Falls to Boise corridor on I-84. Drivers should expect delays on westbound I-84 between mileposts 115 to 120 while tow trucks remove semi trucks that slid off the highway earlier Thursday.
A weather system that moved through the Treasure Valley overnight brought freezing rain and covered roadways with ice and caused such hazardous driving conditions that the Idaho Transportation Department closed the Interstate both ways from milepost 54 (Broadway Avenue exit in Boise) to milepost 121 in Glenns Ferry around 6 a.m.
The closure was extended east, to Bliss (milepost 137) a few hours later.
Idaho State Police reported dozens of slide-offs and crashes along I-84 corridor, so drivers attempting to go between Ada and Canyon counties should be extra cautious.
Ada and Canyon county sheriff's dispatchers report slippery roads and numerous slide-offs and crashes. Ada County dispatchers report four crashes with injuries and 37 without since midnight, in addition to 32 calls for slide-offs or stalled cars.
Ada County Highway District crews have been working on county roads since early this morning. They're putting down sand, salt and de-icer. But officials say the roads remain very slippery.
Sidewalks and parking lots are also slippery, so anyone walking anywhere outside this morning should also be careful.
