If Seattle is in your plans this weekend, check traffic conditions before you head out.
Beginning at 11 p.m. Friday, westbound Interstate 90 will be reduced to one lane near Bellevue Way, then detoured to the express lanes.
The lane closures are scheduled to last until 5 a.m. Monday, and will allow contractor crews to continue upgrading operations and safety systems in the eastbound Mount Baker and Mercer Island tunnels.
