Traffic congestion within the Portland OR and Vancouver WA metropolitan area is not unlike that of other major metropolitan areas within the United States. The congestion along some routes of major transportation corridors have peaks that occur primarily during the morning and afternoon rush hour periods. Traffic congestion along a particular stretch of Interstate 5 that connects Portland and Vancouver experiences perhaps the worst episodes of congestions. Congestion periods of hours is experienced currently and the forecasted trend envisions significantly worse congestion. This congestion along with other inadequacies of the corridor such as unsafe access for pedestrians, bicyclists as well as the lack of adequate transit between the two cities is the reason the Interstate 5 Columbia River Crossing (I5CRC) Project is being considered. This project has been contemplated for some time and is the current subject of a federally required environmental study to develop an acceptable alternative to help alleviate the problems.
