New construction/detour info for the Harbor/Spokane safety project from SDOT:
>As soon as tomorrow, Wednesday, June 13, crews will begin construction of the Harbor Ave SW and SW Spokane St Intersection Improvements project. This Neighborhood Street Fund project will increase the visibility and safety for people walking and biking across Harbor Ave SW and SW Spokane St. We expect construction to last about 6 weeks.
Nighttime and weekend work
One of the first construction activities will be pavement breaking at the intersection of Harbor Ave SW and SW Spokane St in preparation for safety improvement work on the Alki Trail. This work will be done at night and over the weekend to reduce impacts to people driving. For details about what to expect, please see below.
Westbound SW Spokane St will be reduced to one lane of traffic at Harbor Ave SW, except during peak hours (3 PM to 7 PM, Monday through Friday), when it will remain fully open
A uniformed police officer will direct right turns onto northbound Harbor Ave SW from SW Spokane St during work hours
Crews plan to work continuously from 7 PM on Friday, June 15, to 5 AM on Monday, June 18
Sidewalks will be maintained for people walking and biking
