The Washington State Department of Transportation is postponing plans for long-term lane closures on State Route 99 originally scheduled to begin on Wednesday, March 11.

These closures were needed to install several large sign foundations for the SR 99 North Access project. While this work must occur, it will be rescheduled to a later date in an effort to minimize impacts to the traveling public. The public will be alerted in advance of any future lane closures.

Full closure of northbound SR 99 tonight
Contractor crews still plan to close northbound SR 99 to straighten the curve in the highway near Mercer Street.

Tonight, SR 99 will be closed from 10 p.m. to 6 a.m. between the Battery Street Tunnel and Valley Street. All lanes will open at 6 a.m. in time for the morning commute.
