BELLEVUE, Wash. — Heads up, travelers! Two weeks of overnight lane and ramp closures on both directions of Interstate 90 in Bellevue start on Monday, Dec. 1.
The Washington State Department of Transportation (WSDOT) will be installing overhead electronic message signs across both directions of the freeway.
The signs are being added to bridges installed in early November across both directions of I-90. WSDOT says this work supports ongoing construction on the I-90 Sunset Creek fish passage project.
According to WSDOT, people traveling on I-90 between the I-405 interchange and 156th Avenue Southeast can expect at least one lane to remain open each night. Signed detours will guide people nightly around ramp closures in this area.
Construction will not happen during weekends.
