Road & Bridge
UPDATE: Work will now begin Monday, July 12, 2021.
Work will begin Thursday, July 8, 2021 to replace culverts and resurface approximately seven miles of Idaho Highway 11 between Grangemont Road and Headquarters. The highway will be reduced to one lane, with the contractor Knife River scheduled to work weekdays and possibly weekends. Construction is expected to last through early September.
The highway remains reduced to one lane at the slide just outside of Headquarters. The department is analyzing the data from recent soil borings and monitoring devices to determine the severity of the slide and to identify options for the best long-term repair. ITD will then work with the contractor to see if slide repairs may be incorporated into the current project. Another update will be sent once timing of the slide repairs has been determined.
