SH-55 Smiths Ferry to Round Valley closed due to rockslide

SMITHS FERRY – Idaho State Highway 55 (SH-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.

The public can receive direct updates on this slide by signing up for text or email alerts on the project website, itdprojects.org/id55smithsferry, or visit Idaho 511 before leaving on a trip to learn the latest highway conditions.
