Historic Columbia River Highway
Bonneville Lock and Dam, OR

Bonneville Lock and Dam connects Washington and Oregon and is a National Historic Landmark.

There are two visitors centers. The one accessed from exit 40 on Interstate 84 highlights history of the dam and the fish ladder. The one accessed from Washington State Route 14 concentrates on electricity generation, with a trip down into a giant turbine. The Oregon side also includes a fish hatchery with views of salmon and sturgeon.

It takes more than 100 people to operate and maintain Bonneville Lock and Dam each year. The work force includes engineers, powerhouse and lock operators, office administrators, skilled laborers, warehouse workers, biologists and park rangers.
