The Idaho Transportation Department will close U.S. Highway 20 between mileposts 164 and 173 near Fairfield on Wednesday and Thursday, Oct. 16 and 17, as crews pave the newly constructed Willow Creek and Rock Creek bridges. The closures are expected to begin at 11 a.m. and are anticipated to last approximately three hours each day.
The bridge construction projects have been underway since April. Crews replaced aging and corroded culverts with new bridge structures, which are expected to have a longer lifespan, ITD stated. It will also allow the streams in both locations to be restored to a more natural condition, ITD stated.
“With the unexpected drop in temperatures this past month, we have a very narrow window to complete work on these structures,” said ITD south-central Idaho Project Manager Brock Dillé. “Briefly closing the highway will allow us to work more efficiently, and hopefully prevent us from having to return to the area next year to complete the project.”
ITD will place barricades and signage at area intersections to alert travelers. Flaggers will also be present to inform motorists and assist them with determining the best path of travel.
