CASSIA COUNTY, ID — Underway since May 2018, substantial progress has been made on the Interstate 84/86 Salt Lake City Interchange in Cassia County. With this project, the Idaho Transportation Department (ITD) is replacing the old interchange with a new structure that will meet current standards and provide a better driving experience for motorists.

“This is a vital travel and commerce corridor for not only this area, but for the entire state,” said ITD Project Manager Travis Hitchcock. “Our goal is to construct an interchange that will serve motorists for many years to come.”

As work proceeds, drivers should anticipate a continuation of reduced speeds and changing traffic patterns through the work zone.

“There will be varying detours over the next several months as work on specific portions of the structure occurs,” said ITD Project Inspector Jack Kelly. “It’s important that motorists not follow their GPS but instead pay close attention to signage which is in place to safely direct motorists through the area.”

Construction is scheduled to finish by late 2020. Wadsworth Brothers Construction, of Draper, Utah, is the prime contractor on this project.
