From Seattle City Light:
Stewart Street between Minor Avenue and Terry Avenue will be reduced to one lane of traffic, shared by general purpose traffic, bicycles and transit, from 7 p.m. on Friday, April 1 through 6 a.m. on Monday, April 4. This reduction will be in place again from 7 p.m. on Friday, April 8 through 6 a.m. on Monday, April 11.
Additionally, Stewart Street at 7th Avenue will be reduced to one lane of general purpose traffic and one lane for transit April 4 – 7, and Stewart Street at 6th Avenue will have similar reductions on April 8 and 11. Work in these areas will occur between 9 a.m. and 4 p.m.
There also will be nighttime work on Stewart Street at Boren Avenue April 5 – 7 between 7 p.m. and 5 a.m. During this time, Stewart Street will be reduced to one lane of general purpose traffic and one lane for transit.
Access to businesses will be maintained and traffic flaggers and police officers will be on site to assist with vehicle and pedestrian traffic.
From now through August 2016, drivers should expect congestion on Stewart Street between Yale and Westlake Avenues. During this period, the Denny Network project will be installing electrical vaults and duct banks along Stewart Street.
Seattle City Light is constructing an underground electrical distribution network (Denny Network) in city streets throughout the South Lake Union and Denny Triangle neighborhoods. Together with a new substation (Denny Substation) located at Stewart Street and Denny Way, the underground network will ensure reliable power for customers throughout City Light’s service area, including the fast-growing communities of South Lake Union, Cascade, Denny Triangle, Uptown, Belltown and First Hill.
