he Bonneville Dam and locks across the Columbia River were first built in 1896 to allow shipping the bypass the Cascades Rapids. A small power generating plant was built in the 1920. During WWII, the dam was expanded to produce electrical power for the Boeing plants in Seattle and Portland areas. Since then, more generating capacity was added eventually becoming the river control monster it is today.
This was a real challenge riding to the visitor center. along metal bridges (that aren’t friendly to bikes) and all to the parallel railroad tracks in every road. Not a good place for bikes.
