The Idaho Transportation Department will close I-84 under the Karcher Interchange Tuesday and Wednesday nights to place girders on the overpass bridge. Detours will be in place.

Closures will run from 10 p.m. to 5 a.m. each night. On Tuesday night, westbound traffic will be affected, and on Wednesday night, eastbound traffic will be affected.

Motorists traveling westbound on I-84 Tuesday night will:

  1. Exit I-84 at the Northside Interchange (Exit 35).
  2. Travel north on Northside Blvd.
  3. Turn left on to Karcher Road.
  4. Travel west until you reaching the Karcher Interchange westbound on-ramp.
  5. Use the Karcher Interchange westbound on-ramp to merge back on to westbound I-84.

Motorists traveling eastbound on I-84 Wednesday night will:

  1. Exit I-84 using the Karcher Interchange eastbound off-ramp (Exit 33).
  2. Cross Karcher Road.
  3. Use the eastbound on-ramp to merge back onto I-84.

The girders were fabricated locally and will support the new westbound lane on Karcher Road over the interstate. ITD will host a Facebook live event during the girder placement on Tuesday, June 10. To tune in visit the ITD Facebook page.

Improvements on this project include:

  • Adding a free running right hand turn at the westbound off-ramp
  • Paving a third westbound lane on Karcher Road from the westbound off-ramp to Sundance Road
  • Reinforcing the Karcher Interchange and Indian Creek bridges to support the new lane
  • Updating signal equipment and adding a pedestrian flashing beacon at the eastbound on-ramp
  • Building a separated mixed-use path on the north side of Karcher Road

These improvements will increase safety and traffic flow at the interchange. Construction is expected to finish in fall 2025.
