The Columbia River Crossing (CRC) project will improve the mobility, reliability, and accessibility for automobile, freight, transit, bicycle, and pedestrian users of the Interstate 5 (I-5) bridge over the Columbia River and for five miles of I-5 between State Route 500 (SR 500) in Washington and Columbia Boulevard in Oregon. Heffron Transportation prepared all analyses related to truck conditions and operations in this corridor. This work included detailed documentation of existing truck volumes, travel routes, and issues within the bridge influence area in order to define how I-5 can be designed to meet the important economic need for truck mobility between Washington State and Oregon.
