Moveable Bridges on State Routes

The Washington State Department of Transportation operates 17 moveable bridges on state routes. Federal Law ( Title 33, Part 177 Draw Bridge Operations ) gives marine traffic the right-of-way over vehicular traffic. WSDOT works with the US Coast Guard to create reasonable restrictions on marine openings (for vessels under 5,000 gross tons) during peak travel times to ease congestion for drivers when possible.
