Commuters who traverse the expanse between Seattle and Bellevue via eastbound Interstate 90 need to gear up for upcoming delays. According to the Washington State Department of Transportation (WSDOT), significant bridge repair work will commence on Thursday, Sept. 18, as part of the I-90/East Channel Bridge project. WSDOT announced an 18-day lane reduction and ramp closures that are set to disrupt daily transit routines, particularly affecting those moving off Mercer Island onto eastbound I-90.
With details on what to expect, the traffic on eastbound I-90 will be narrowed down to three lanes starting from the threshold of Island Crest Way and stretching towards Bellevue Way. Beginning during the project's initial phase, the eastbound I-90 on-ramp from East Mercer Way will shut down to facilitate the installation of a new bridge expansion joint. Trying to accommodate the work schedule, crews will focus on the south section first, forecasting that the ramp will reopen within six to eight days after Sept. 18.
Adding to the commuter constraints, the eastbound I-90 high-occupancy vehicle (HOV) on-ramp from 80th Avenue will be sealed off for the entirety of the project. To pave the way for construction activities like lane shifts, barrier installations, and road restriping, eastbound I-90 will undergo occasional, brief closures. WSDOT has yet to announce exact times and dates for these disruptions, but commuters should stay alert for updates as construction approaches.
Underpinning this extensive project is the crucial need for repairs as detailed by WSDOT; the modular assembly joints of the eastbound I-90 East Channel Bridge, original to its 1988 inauguration, have succumbed to the ravages of time and use. An incident in January 2024 marked the failure of a joint in the right lane. These replacements are not just preventative maintenance; they are acts of preservation, aimed to bolster the bridge’s structural fortitude for years ahead. This bridge navigates nearly 75,000 vehicles on its eastbound carriageway every day, a testament to its pivotal role in the region's transport framework.
