The eastbound lanes of the Spokane Street Viaduct are closed this weekend, until Monday morning, January 30, at 5 a.m.  During the weekend closure, either the First Avenue S off-ramp or the Fourth Avenue Loop ramp will remain open, permitting motorists to use the eastbound S Spokane Street lower roadway to reach either the I-5 ramps or Columbian Way S.

These same eastbound lanes of the Spokane Street Viaduct will also be closed each weekday night from Monday, January 30, through Friday, February 17.  These closures, needed in large part for the demolition of the barrier on the southern side of the existing structure, will also begin at 9 p.m. each evening and end at 5 a.m. the following morning.  Either the First Avenue S off-ramp or the Fourth Avenue Loop ramp will remain open during each of these closures, although on some nights the work will also require the closure the lower eastbound roadway.  In such cases, motorists wishing to access the I-5 ramps or Columbian Way S will be detoured north to S Lander St, where they will be directed to turn east to Sixth Avenue S, they will then turn south onto Sixth and proceed to S Spokane Street, where they can  turn east onto the appropriate on-ramp. 

At 1:30pm on Saturday, the Seattle Police Department deployed more officers to help with the ongoing traffic jam.
