SEATTLE — Friday is the first day of a two-week closure of the Alaskan Way Viaduct. Many commuters are planning ahead by adjusting work schedules or making plans to bike, bus or take other transportation to work.
State Route 99 through downtown Seattle fully closed at 12:01 a.m. Friday. Transportation officials are warning of heavy congestion throughout the region.
The highway between South Spokane Street and the south end of the Battery Street Tunnel is being closed so the tunneling machine known as Bertha can begin digging underneath the roadway near Yesler Way.
About 90,000 vehicles move through this stretch of the viaduct each day.
