Eastbound Interstate 90 travelers should plan to use the express lanes for two nights next week as crews shift lanes at the west end of Mercer Island to create a work zone in the median between the eastbound roadway and the express lanes.
Beginning at 11 p.m. each night, June 8-9, crews will shift all eastbound I-90 traffic between Rainier Avenue South and Bellevue Way to the express lanes. Crews will also close the Rainier Avenue South on-ramps to eastbound I-90. All eastbound I-90 lanes and ramps will reopen by 5 a.m. This work is weather dependent and is subject to change.
During the closures, drivers from Rainier Avenue South will be detoured to South Dearborn Street and then to Fourth Avenue South to eastbound I-90. Drivers accessing eastbound I-90 from Mercer Island will not be affected by the closures.
This traffic shift will allow crews to perform work to convert the existing reversible ramp from the express lanes to Island Crest Way to an eastbound HOV off-ramp.
The work is part of the Washington State Department of Transportation and Sound Transit’s I-90 Two-Way Transit and HOV Operations project which preserves the three general purpose lanes while adding all-day carpool lanes to I-90 and direct access ramps for transit, carpools, and vanpools. In mid-2017, Sound Transit contractors will begin work on the I-90 express lanes to operate exclusively for light rail as part of the East Link light rail project. The 14-mile East Link project, set to open in 2023, includes 10 new stations connecting Seattle, Mercer Island, Bellevue and Overlake.
