(Portland, OR) -- The U.S. Coast Guard has approved a 116-foot fixed-span bridge to replace the Interstate Bridge between Portland and Vancouver. Not having to build a lift-span will reduce costs. The Coast Guard says 99 percent of river traffic will be able to pass under the bridge. It won't affect air traffic arriving and departing from Portland International Airport. The next step for the project is to complete the final Environmental Impact Statement and get a Record of Decision which allows construction.
