I-5 Columbia River Crossing OK’d
The current I-5 crossing of the Columbia River consists of two side-by-side bridges. The bridge carrying northbound traffic was built in 1916, and the bridge carrying southbound traffic was built in 1958. Both bridges are inadequate to carry the current traffic volumes, and the mechanical lift spans that are raised to accommodate river traffic bring interstate traffic to a standstill. The geometry of the bridges makes the existing crossing one of the most unsafe highway locations on the I-5 corridor - its crash rate is double that of similar bridges. In addition, the bridge does not meet the current bridge design standards for earthquakes.
