As noted in today’s morning traffic watch, one of West Seattle’s major east-west routes, Sylvan Way, will be closed much of this weekend, without major advance notice aside from sparse signage. Today SDOT was finally able to tell us this is a Seattle Public Utilities project, and we have obtained more information through SPU spokesperson Sabrina Register:
This is SPU drainage crew work. They are responding to some localized flooding issues that were reported by the community last year. SPU is installing one inlet and one catch basin and needs to trench across the street to connect to them to the drainage mainline.
This work will occur Saturday and Sunday, 8 am to 5 pm, and a detour will be in place. Outside of working hours, the crew will be able to reopen the roadway and allow traffic on Sylvan.
