Maintenance Work Will Impact Traffic over Hells Canyon Dam

OXBOW, Oregon — Traffic over Hells Canyon Dam will periodically be limited to one lane over the next several weeks while Idaho Power crews perform maintenance on the dam.

Beginning Monday, Aug. 26, motorists may experience delays between 8 a.m. and 4 p.m. Delays will usually be brief, although vehicles 8-feet wide or more may be delayed up to an hour.

Crews will be replacing spillgate cables on the dam. The work requires a large crane on top of the dam, which will reduce traffic to a single narrow lane. The project is expected to be complete by Oct. 21.

Located 21 miles downstream of Oxbow Dam, Idaho Power’s Hells Canyon Dam began generating electricity in 1967 and has a nameplate generating capacity of 391,500 kilowatts.
