I-84 nighttime closure at the Karcher Interchange Wednesday, August 20

I-84 will be closed overnight on August 20 (10 p.m. to 5 a.m) under the Karcher Interchange. This closure will allow crews to pour concrete for the newly widened SH-55 Bridge. This work is necessary to widen Karcher Road (SH-55) over the interstate.

Motorists traveling eastbound 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.

Motorists traveling westbound 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.

These improvements are part of a larger effort to improve traffic flow and safety at the interchange and along Karcher Road.

Improvements being built as a part of the 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
