Drawbridge Operation Regulations; Columbia River, OR

The Coast Guard proposes to temporarily change the operating regulations of the dual vertical lift bridges on Interstate Highway 5 across the Columbia River, mile 106.5, between Portland, OR and Vancouver, WA to accommodate a major rehabilitation of the mechanical and electrical systems of the bridges. From July 15, 2004, to August 6, 2004, the lift spans would be closed and from August 6, 2004, to October 15, 2004, the draws would open for the passage of vessels once every two weeks according to an established schedule. The affected period approximates the annual season of low water on the Columbia when the maximum vertical clearance will be available.
