County to hold meeting on Novelty Bridge replacement

   The King County Road Services Division will be holding an open house on the Novelty Bridge replacement project on Tuesday, July 14, 5-7 p.m. at Cedarcrest High School, 29000 NE 150th St., Duvall.
   King County has been working for several months with residents, businesses and the city of Duvall to identify ways to minimize environmental and traffic impacts associated with the replacement of Novelty Bridge, located on NE 124th St. between West Snoqualmie Valley Road and SR-203.
   Based on that input and involvement, the county has now refined its plans to include a shorter construction schedule, significant environmental mitigation efforts and additional improvements to NE 124th Street aimed at reducing flooding on the roadway.
   Bridge replacement plans
   One major project change involves a compressed construction schedule. Based on an intensive construction analysis, the county now anticipates it can perform the most critical bridge replacement work and limit the closure of NE 124th St. to seven or eight months - four to five months less than its original timeline. The county will adopt six-day work schedules and overtime, if necessary, to fast track the project.
   In response to community feedback, the county also plans to widen NE 124th and add shoulders between W. Snoqualmie Valley Road and SR-203. The road will also be raised as much as 14 inches in places to help protect the road from flooding.
   The total projects, costing an estimated $10 million, will take about one year to complete with construction expected to begin in mid-2000. The new structure will be a 623-foot-long bridge that includes a tied-arch main span, precast concrete girder approach spans and two 11-foot travel lanes with two 8-foot shoulders.
   Steps to keep traffic moving
   The county has also developed a proposal to improve traffic flow on roads that will be used as detour routes while the project is underway. Those improvements include:
   The county would work to have the traffic improvements in place prior to the start of the bridge replacement project.
   Environmental mitigation
   King County has also identified a number of measures aimed at minimizing environmental impacts associated with construction. Plans call for relocating four small stream channels away from the road to improve fish habitat.
   The streams and nearby wetlands will also be revegetated with native plants to improve habitat. Plans also call for habitat and stream improvements on the Snoqualmie River as part of the bridge replacement.
   "The city of Duvall appreciates the effort and cooperation extended by King County regarding this project and is very supportive of efforts to minimize the down time and street closure," said Duvall City Director Jim Bourasa. "We applaud these efforts to significantly reduce the closure of NE 124th. This cooperative effort will certainly help reduce the overall inconvenience to motorists."
   During the open house, residents will have an opportunity to view displays, ask questions and offer their comments. Residents will also be invited to comment on the types of environmental mitigation efforts being proposed. Written comments will also be accepted and should be forwarded by July 31 to Gwen Lewis, King County Road Services Division, King County Administration Building, Room 900, 500 Fourth Ave., Seattle, 98104.
