Drivers heading west across Lake Washington, including fans heading to Saturday night’s Sounders match, should plan ahead for construction and delays tonight through Monday as part of ongoing work to add around-the-clock HOV lanes to Interstate 90.

Beginning at 11 p.m. on May 20, until 5 a.m. on May 23, westbound I-90 will be reduced to a single lane near Bellevue Way, and all traffic will be routed into the express lanes.

During the lane reduction, contractor crews working for the Washington State Department of Transportation and Sound Transit will continue upgrading the operations and safety systems inside the Mount Baker and Mercer Island tunnels as part of the I-90 Two-Way Transit and HOV operations project.

Drivers traveling to Seattle from the Eastside should plan for lengthy delays along Interstate 405, westbound State Route 520 and westbound I-90 in Bellevue.
