The Interstate 5 Bridge between Portland, Oregon and Vancouver, Washington has a lift span, which allows Columbia River marine traffic to pass. - 

This week we got a question from a listener in Vancouver, Washington who wanted to know how much a deteriorating bridge is costing the area. The nearly 100-year-old overpass that connects Vancouver to Portland, Oregon was originally made for the Ford Model T, horses and buggies. The narrow six-lane bridge is now a crossing point for cars, commercial trucks, cargo ships, and even airplanes, which creates severe traffic jams along one of the major transportation corridors in the Pacific Northwest.
