With crews set to close the westbound Interstate 90 floating bridge, transportation planners plan to reroute King County Metro buses. The changes will impact Issaquah riders.
State Department of Transportation crews will shut down the bridge July 5 for round-the-clock work. The artery across Lake Washington is expected to reopen July 20.
To help lessen traffic congestion, Metro planners will reroute Seattle-bound buses that travels westbound on I-90 from the Issaquah Transit Center, the Issaquah Highlands Park & Ride, Eastgate, Sammamish and Snoqualmie. Boarding locations for riders who depart from the Issaquah centers will be unaffected.
Metro planners provided a complete list of service changes on the agency’s Web site.
Westbound buses headed toward the floating bridge will be routed off of I-90 at 142nd Place Southeast and re-enter the interstate near Bellevue Way. Planners said the detour will divert buses around several anticipated bottlenecks.
Buses will likely be delayed as a result of lane closures related to bridgework. On mornings during the shutdown, all westbound traffic will be funneled to the express lanes — reducing the number of available lanes from five to two. The westbound afternoon commute will be cut from three lanes to two.
As the shutdown loomed, transportation officials urged employees and supervisors to talk about working alternate schedules or telecommuting to avoid peak travel times.
During the shutdown, crews will install a pair of new expansion joints weighing 65 tons each. Joints — some of the largest in the world — allow the bridge to bend with traffic, weather and the water level in Lake Washington.
When the westbound span is closed to vehicles, four 12-person demolition crews will work 10-hour shifts to remove the existing, cracked joints and install new joints.
