Washington State Department of Transportation (WSDOT) has released an update regarding the upcoming SR 500 & St. Johns Blvd. Interchange Project. This massive transportation project will greatly impact businesses and the flow of traffic in and around Rosemere.
Update from WSDOT, December 2010:
The year is rapidly drawing to a close and the SR 500, St. Johns Blvd. Interchange project team wants to provide the public with an update on where the project stands as we head toward 2011 and into construction.
This fall, WSDOT hosted several public meetings and heard your questions and concerns about the project. In response to your feedback, project engineers redesigned the construction sequencing plan to avoid a full closure of St. Johns Blvd. After several months of working through the details, WSDOT is ready to advertise the project for construction and deliver this vital safety improvement to the community.
Anticipated project timeline for 2011
• January: Advertise project to contractors
• April: Award construction contract
• May/June: Construction scheduled to begin
Construction overview and traffic impacts
The new interchange will be built in three stages:
• Stage 1: Crews begin construction and build a temporary detour, or “shoofly,” route along St. Johns.
• Stage 2: Traffic on St. Johns is shifted to the shoofly route. Crews build the new bridge over SR 500 and begin constructing new interchange ramps
• Stage 3: Crews connect SR 500 and St. Johns with interchange ramps and complete construction.
Traffic impacts are estimated to last for up to a year and a half. Drivers can expect to see narrowed lanes on SR 500 and St. Johns, and restrictions on left and right turns throughout the project. WSDOT will keep St. Johns and SR 500 open to through traffic and pedestrians during construction. There will be occasional short-term weekend or nighttime closures for girder setting or traffic shifts.
