ITD passes major milestone, installs SH-16 flyover girders.

The Idaho Transportation Department will close eastbound I-84 between Garrity (Exit 38) and Ten Mile (Exit 42) from Jan. 16 at 10 p.m. until Jan. 19 at 5 a.m. What to expect: 

  • Eastbound I-84 will exit and re-enter using the new ramps for the duration of the closure. See detour map. 
  • Westbound I-84 will be reduced to two lanes each night. All westbound lanes will be open from 5 a.m. to 10 p.m. 

This closure will allow crews to install 16 girders for the first of two new flyover ramps. Each girder weighs approximately 42,000 pounds and averages around 117 feet long. 

Ongoing nighttime lane restrictions in this area will continue through March in both directions. At least two lanes will remain open overnight. 

“The I-84 and SH-16 Interchange is part of the long-term vision for SH-16,” Matthew Kreizenbeck, ITD community outreach coordinator said. “When complete, I-84 traffic will be able to seamlessly transition to SH-16, creating a limited-access freeway between I-84 and SH-44.”
