OXBOW, Oregon, April 3, 2015 — Vehicles crossing Hells Canyon Dam will continue to be restricted to one lane for several weeks while Idaho Power crews perform maintenance on the dam.
Flaggers at either end of the dam will control traffic while work is taking place, usually between 8 a.m. and 5:30 p.m. each day, Monday through Thursday. Although flaggers will not be present at night or on Fridays, the road will still be restricted to one lane by equipment on the dam; motorists are urged to use extra caution when crossing.
Additionally, a reader board is in place at Oxbow to warn drivers of the road restriction.
The lane restriction is necessary to allow crews to safely perform maintenance work on the dam’s intake gates. Completed in 1967, Hells Canyon Dam is Idaho Power’s second-largest dam in terms of electricity generation. It has a nameplate capacity of 391.5 megawatts.
