Idaho State Highway 55 between Smiths Ferry and Round Valley Road has been closed due to a rockslide overnight.

The road will remain closed until further notice. This slide occurred in a different area than the rockslide that closed SH-55 late last fall. Geotechnical experts need to assess the stability of the hillside and determine next steps to reopen SH-55 safely. Construction crews are heading to the area.

Until the highway is reopened, travelers can use U.S. Highway 95 as the alternate route.
