Description 

This bridge is a retrofit of an earlier rail crossing before the river was raised by Lower Granite Dam. The original swing drawspan was phased out in favor of a new lift span, opening the river to barge traffic. The ports immediately upstream of this bridge make up Idaho's only seaport, and allow inland wheat farmers to inexpensively transport their crops down the Snake and Columbia Rivers to the Pacific Ocean.
