THE FINISH LINE IS IN SIGHT!

With two quarters of 2018 already behind us, it's hard to contain our excitement. Every day brings us closer to project completion! Recent noteworthy milestones include: starting the energization process in the substation, restoring and re-opening John Street, and installing new sidewalks and curb ramps throughout the Cascade Neighborhood. Community benefits that took take shape this quarter include the off-leash areas, handrails, and the waterproof membrane for the elevated walkway.

If you've followed along since the beginning of the project, the most anticipated times are yet to come.

Denny Way Daytime Lane Closures Continue


Periodic daytime closures of the right lane of westbound Denny Way between Stewart Street and Minor Avenue N. and the adjacent sidewalk will continue. The right lane will be closed at times between 9 a.m. and 3 p.m., Monday through Friday. The sidewalk will be closed around-the-clock. During these closures, crews will be installing landscaping, lighting, Silva Cells, and building the sidewalk.

Ongoing Work on Community Features at the Substation Site


Work on the off-leash area continues, community spaces are progressing, and Silva Cells have been installed around the site for future landscaping. Inside the substation, equipment testing and finishing work inside the substation's buildings continues. Work hours are 7 a.m. to 5 p.m., Monday through Friday and 9 a.m. to 5 p.m. on Saturday.


Denny Network


In the third quarter of 2018, crews will continue to restore neighborhood streets and sidewalks as duct bank installation nears completion. Other upcoming visible work in and around the substation includes completing alley concrete paving on the east side of the substation, wrapping up work on the elevated walkway and installing project art. We will also continue to advance the Cascade Neighborhood Street Improvements.
