Capitol Hill Community Post | Denny Substation Construction Work Will Impact Denny Way Starting Oct. 14

From Seattle City Light

Five weeks of Denny Substation construction expected to cause significant traffic delays

SEATTLE – Seattle City Light is advising drivers and commuters to prepare for five weeks of lane closures on Denny Way between Stewart St. and Minor Ave N, beginning Friday, Oct. 14. Crews will be installing underground utilities for the Denny Substation.

From Friday, Oct. 14, at 11 p.m., to Monday, Oct. 17, at 5 a.m., all lanes on Denny Way will be closed while crews restripe the roadway. After 5 a.m. on Monday, Oct. 17, Denny Way between Stewart St. and Minor Ave N will be reduced to one lane in each direction 24 hours per day, 7 days a week, for five weeks. On the weekend ofNov. 19 and 20, crews will close all lanes of Denny Way once again in order to restore the roadway to its normal configuration. All lanes on Denny Way will reopen on Monday, Nov. 21.

During the lane closures, travelers on Denny Way and Stewart St. should expect significant delays and are encouraged to use alternate routes. King County Metro Bus 8 will be directly impacted by the closures — the westbound Denny Way and Stewart Street bus stop will be temporarily closed. The eastbound bus stop will remain open, but riders should expect delays.

Seattle City Light is working with the Washington State Department of Transportation (WSDOT) and transit providers to inform travelers about the closures and to discourage the use of the Stewart Street exit from southbound I-5. Access to southbound I-5 from Yale Avenue will be maintained, but drivers should expect delays. Uniformed police officers will be on site to help direct traffic around the work zone.

Project Background: As part of the Denny Substation Program, Seattle City Light is building a new substation (Denny Substation) and underground electrical distribution network (Denny Network) and designing a transmission line (Denny-Massachusetts Transmission Line) that will ensure more reliable power delivery to customers in and beyond the South Lake Union and Denny Triangle neighborhoods. The new substation, located on Denny Way near Stewart St, will be City Light’s first and largest substation in 30 years. The Denny Substation Program will increase system-wide reliability and operational flexibility, achieving a major electrical system upgrade for the city of Seattle.

Nothing about how the 8 will function when the street is entirely closed, like it will be in three days?

I don’t see any info on the Metro Transit website either, I wonder if anyone told them about it.

Oh jeez, the poor 8 bus and its riders. As if it wasn’t so unreliable now.

This intersection is a disaster in the mornings. Vehicles on Stewart constantly blocking traffic and pedestrians crossing East/West on Denny.

Why does police are not out citing drivers (including metro) who block East bound traffic, West bound pedestrians on Denny is beyond me. If its not enforced during this construction, it will result in gridlock.

Oh, boy! Denny Way is already gridlocked much of the day….especially driving eastbound. This is going to make it much, much worse.
