Travel Advisory | Weekend closure of S Columbian Way between S Snoqualmie St & S Oregon St

Thanks to your Levy to Move Seattle tax dollars and our Safe Routes to School program, construction has started on 15th Ave S to increase safety for people traveling along this important connection between Beacon Hill and Rainier Valley! 

A small section of S Columbian Way will be closed the next two weekends. The closure is just south of the intersection of 15th Ave S and S Columbian Way where we’re making significant improvements to increase safety for people walking, rolling and riding bikes.  

Drivers, cyclists, and pedestrians should follow detour signs to take 15th Ave S and S Snoqualmie St. around the construction zone.

Drivers, cyclists, and pedestrians should follow detour signs to take 15th Ave S and S Snoqualmie St. around the construction zone.

Here’s a quick snapshot of what you need to know:  

Schedule: 

  • February 27 (Saturday) at 6:00 am – February 28 (Sunday) at 5:00 pm 
  • March 6 (Saturday) at 6:00 am – March 7 (Sunday) at 5:00 pm 

Please note that construction schedules are subject to change. 

Detour Information: 

  • Drivers, cyclists, and pedestrians should follow detour signs on 15th Ave S and S Snoqualmie St.
  • Business access will be maintained.

Transit Impacts: 

  • The northbound bus stop on Columbian Way north of S Snoqualmie St will be temporarily out of service during the closure.  
  • North- and southbound riders can access stops at the south end of the closure (the intersection of S Columbian Way and S Snoqualmie St) and at the north end of the closure (on 15th Ave S, south of S Nevada St).   

Please stay safe by observing speed limits and following direction of uniformed police officers. Pedestrians and bicyclists are encouraged to take advantage of the greenway, on 14th Ave S and 13th Ave S, to avoid the construction zone. 

There may be noise and dust associated with this work.  Crews will do all they can to complete this work as safely and efficiently as possible, and to minimize disruptions to the traveling public.
