Denny Substation Construction to Cause Denny Way Lane Closures, Starting Oct. 14

Denny Substation construction zone.

Seattle City Light is asking travelers to prepare for five weeks of lane closures on Denny Way between Stewart St and Minor Ave N beginning Friday, Oct. 14. During this time, 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. Starting at 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 four weeks. Over the weekend of Nov. 19 and 20, crews will close all lanes on 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 St 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.

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.

Entry road to Carkeek Park to be closed for one day on May 8

SDOT will complete repaving project

Repaving work by the Seattle Department of Transportation (SDOT) will require a one-day closure of NW Carkeek Park Road, the road into Carkeek Park in northwest Seattle. The road into the park is expected to be closed to vehicular traffic on or around Thursday, May 8 between 8 a.m. and 5 p.m. The repaving work will be completed weather permitting.

Carkeek’s regular operating hours are from 6 a.m. to 10 p.m., so from 6 a.m. to 8 a.m. on May 8, the entry road will be open as usual. Bicycle and pedestrian access will be curtailed on the entry road on May 8, but unpaved trails into and through the park will be open as usual.

The repaving of NW Carkeek Park Road is part of a larger repaving project by SDOT in the immediate surrounding neighborhood, including 8th Ave. NW, NW 114th Pl., NW 116th St., 6th Ave. NW and NW 117th St.

The repaving project is expected to be completed over a period of two weeks beginning May 6, 2014 and ending on Friday, May 16. Typical working hours are between 8 a.m. and 5 p.m. unless otherwise noted.
