Road Closure Will Restrict Travel Over Hells Canyon Dam

Maintenance work will cause traffic delays the week of July 29, and the road over the dam will be closed Aug. 5–8, with vehicles only allowed to cross between noon and 1 p.m.

OXBOW, Oregon — Visitors to Idaho Power’s Hells Canyon Dam could experience traffic delays the week of July 29, and the road over the dam will be closed Aug. 5-8 while crews perform maintenance.

Flaggers will direct traffic while trucks move large beams called stop logs from a staging area to the dam July 29–Aug. 1. Stop logs are used to control water flow through the dam to allow for maintenance.

Traffic over the dam will be closed from 8 a.m.–4 p.m. MT Aug. 5–8 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.
