Drawbridge Operation Regulations; Columbia River, OR and WA

The Coast Guard is proposing an amendment to the drawbridge regulations governing the operation of the twin Interstate 5 drawbridges across the Columbia River, mile 106.5, between Portland, Oregon and Vancouver, Washington. The original Notice of Proposed Rulemaking proposed an extension of the morning and afternoon time periods when the draw need not open for the passage of vessels without regard to vessel type or river flow condition. This supplemental notice of proposed rulemaking proposes an amendment which would provide for relatively uninterrupted vehicular flow during peak traffic times while being less restrictive to commercial navigation during periods of high river flow conditions.
