The Rock Island Railroad Bridge is BNSF Railway's bridge across the Columbia River, at Rock Island, Washington. The structure consists of one through truss, one deck truss, and an approach trestle.
History
The bridge was originally built in 1892 for the Great Northern Railway. Bridging the Columbia River was an important component in completing Great Northern's transcontinental link the following year. The site was chosen at Rock Island, Washington for being the shortest distance between the banks of the Columbia River in Washington state. In 1925, it was decided to strengthen the main span in anticipation of increased traffic and heavier trains by reinforcing the structure with an additional outside truss frame.
