ITD takes next steps in historic three-level interchange.

The Idaho Transportation Department will detour westbound Interstate 84 traffic at night between Ten Mile (Exit 42) and Garrity (Exit 38) from Thursday to Monday.  

What to expect:

  • Westbound I-84 will be closed from 10 p.m. to 6 a.m. each night.
  • Traffic will exit at Ten Mile and be detoured down Franklin Road to the Garrity Interchange. See detour map.

As a reminder, these closures will allow crews to continue to set girders for the future I-84/SH-16 System Interchange 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 April in both directions.
