BELLEVUE: Overnight I-90 lane, ramp closures begin Monday, Dec. 1, for sign installation

Two weeks of overnight lane and ramp closures on both directions of I-90 in Bellevue start Monday, Dec. 1, for the installation of overhead electronic signs across both directions of the freeway.

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 around nightly ramp closures in this area.

Construction will not happen during weekends. 

Westbound I-90 closure details

The following closures are planned from as early as 9 p.m. to 5 a.m. nightly Monday, Dec. 1, through Friday morning, Dec. 5:

• Up to three lanes between I-405 and 156th Avenue Southeast.
• Ramps to northbound and southbound I-405.
• On-ramps from 142nd Place and 148th, 150th and 156th avenues southeast.
