Work planned on: Electrical Improvements Along Burke-Gilman
Seattle City Light is continuing work to upgrade the electrical reliability and capacity of the system feeding the University of Washington. The final phase of the project requires intermittent detours on the Burke-Gilman Trail while underground conduit is installed between City Lights substation near I-5 and the UWs substation near 15th Ave NE (see map). The final phase of work is scheduled to start Saturday, Jan. 17, and is expected to last until mid-February.

Pedestrians will be detoured onto sidewalks while cyclists will be detoured onto preexisting designated bike lanes and detour lanes protected by traffic cones bolted to the asphalt. View a short one minute video showcasing the detour. Signage will direct cyclists and pedestrians at way points along the detour route. See example signage.

Westbound motorists on NE 40th Street will not be permitted to turn left onto NE Pacific Street at 5th Avenue NE to accommodate the new temporary lanes for cyclists. Traffic will be detoured there and can rejoin westbound NE Pacific Street at Latona Avenue NE.

Seattle City Light is working to improve the reliability and capacity of the electrical system feeding the University of Washington (UW). Five sections of the Burke-Gilman Trail west of 15th Avenue NE will be closed, each during five different planned phases of the work. The project is being coordinated with the UWs additional trail improvements east of 15th Avenue NE.
