History

The bridge was originally built in 1892 for the Great Northern Railway and was the first bridge to span the Columbia River. 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.[2]
