Columbia River Crossing (21 of 29)

Columbia River Crossing, the Interstate Bridge, is actually made up of two side-by-side bridges. The northbound bridge was built in 1917 and the southbound bridge in 1958. After serving both Washington and Oregon so well for over 90 years, it is time to replace the two structures to best meet the next century's growing travel needs across the Columbia River. Today, the Interstate Bridge carries 135,000 vehicles per day. A replacement bridge will be designed to address future traffic demand, eliminate the need for bridge lifts and meet current seismic standards.
