Winter weather forces road closures across the state

BOISE—Blizzard conditions across much of the state has caused the Idaho Transportation Department to close several routes.  

Current closures include:  

Southwest Idaho: 

  • State Highway 21 from Grandjean Junction to Banner Summit 

  • State Highway 21 from Idaho City to Lowman 

South-Central Idaho:  

  • U.S. Highway 93 from Jerome to Shoshone 

  • U.S. Highway 20 from Fairfield to Mountain Home 

  • U.S. Highway 30 from Hansen to Murtaugh

Plows will be out in full force today and until the winter weather subsides. The department asks that those who do not need to travel stay home or time their trips around weather conditions.  

To share the road safely with plows, travelers are reminded to:  

  • Never pass a plow on the right.  

  • Give plows room to work by maintaining at least a three-second following distance.  

  • If multiple plows are working in tandem, do not attempt to move between them.  

  • Stay out of the blind spots.  

  • Drive for conditions.  

  • Allow extra time to travel.

More closures could be possible as the system moves through the state. Road conditions are updated 24/7 at 511.idaho.gov. Drivers are reminded to know before they go and visit the website or check the 511 app before traveling.
