Denny Way closed for construction all weekend

Updated:

Drivers in downtown Seattle will need to avoid Denny Way over the weekend.

All lanes will be closed between Stewart Street and Fairview Avenue North to reconfigure and restripe the road.

Crews have been installing underground utilities for Seattle City Light’s Denny Substation on Denny Way for the last month. 

The closure will start Friday at 11 p.m. and will last until 5 a.m. on Monday. 

Drivers on other sections of Denny and Stewart should expect delays and may want to use alternate routes.

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.
