BOISE – The Idaho Transportation Department will begin construction Monday to repair significant barrier damage on the Interstate 184 Flying Wye flyover and westbound Interstate 84.

The damage was caused by a recent crash and presents a safety hazard to motorists. Contractors will restore the bridge barriers, which are designed to contain vehicles during collisions, protecting both traffic on the flyover and traffic below on I-84.

Drivers should expect:

  • Intermittent nighttime two-lane closures on westbound I-84
  • A single-lane closure on the flyover for approximately two weeks
  • Reduced speeds in the work zones

Motorists are advised to plan ahead, allow extra time, and drive with caution through the work zone. For real-time traffic updates and road conditions, visit 511.idaho.gov or use the Idaho 511 app.
