Woodinville-Duvall Bridge closed for summer

After more than 50 years of service, the Woodinville-Duvall Bridge is getting a major upgrade this summer to improve safety for motorists. But, the project will require King County to completely close the bridge from Monday, June 24, through late September.
   During routine inspections last summer, engineers discovered many cracks on the 12 spans of reinforced box girders that make up the superstructure of the bridge. Water seeps through those cracks and corrodes the reinforcing steel, accelerating structural deterioration and shortening the bridge's life. To protect safety, the county posted a 40,000-pound load-limit restriction for the bridge last July.
   Starting Monday, a contractor will be installing steel rods in the superstructure of the bridge, resurfacing and sealing the deck, and upgrading the guardrails. It is a $2.5 million project.
   The King County Roads Services Division plans more work in 2004, when additional seismic retrofitting will be done on the bridge. The seismic retrofit should be able to be completed without full closure of the bridge.
   During the closure this summer, all downtown Duvall businesses will remain open during construction. Several alternative routes are available, including:
   Heading south from Snohomish County: Take the High Bridge Road, head east on Tualco Road to get to State Route 203 and south to Duvall;
   Heading east on Woodinville-Duvall Road: Go south on West Snoqualmie Valley Road, east on Northeast 124th Street, and back north to Duvall on SR 203;
   Heading northeast from Redmond and Sammamish: head east on Ames Lake Road and Carnation Farm Road, or east on Tolt Hill Road, then head north on SR 203.
   To help motorists gauge the flow of local traffic, two traffic cameras have been installed - at Northeast 124th Street and West Snoqualmie Valley Road, and at Northeast 124th Street and SR 203. These cameras can be viewed on the My Commute website at http://www.metrokc.gov/kcdot/mycommute/.
   During the closure, Metro Transit bus routes 232, 311 and 929 will be rerouted via SR 203, Northeast 124th Street and West Snoqualmie Valley Road Northeast. Also, stops in Duvall on Main Street north of Ring Street and stops on the Woodinville-Duvall Road between Main Street and West Snoqualmie Valley Road Northeast will not be served during the closure. In downtown Duvall, passengers should use the temporary bus stop on Brown Avenue at Richardson Street.
   Built in 1951, the Woodinville-Duvall Bridge is 1,182 feet long and carries more than 17,000 vehicles daily. More than one in ten of those vehicles are trucks.
