Travel Over Hells Canyon Dam Will be Restricted Aug. 19-22

The road over the dam will be closed Aug. 19–22, with vehicle crossing allowed only between noon and 1 p.m.

OXBOW, Oregon — Travel over Idaho Power’s Hells Canyon Dam will be restricted Aug. 19–22 while crews perform maintenance. This affects access to the U.S. Forest Service’s visitors center as well as the boat launch below Hells Canyon Dam.

Idaho Power crews will install large beams called stop logs, which control water flow through the dam to allow for maintenance. A large crane required for the installation will prevent traffic from crossing the dam during the work.

The road over the dam will be closed from 7:30 a.m. to 4 p.m. MT Aug. 19–22 while the stop logs are installed. A single lane will be opened from noon to 1 p.m. each day to allow traffic to cross. All Idaho Power operations in Hells Canyon are conducted on Mountain Time.
