Electrical Infrastructure Improvements Near First Avenue South and South Jackson Street

Starting as early as Thursday, August 3, Seattle City Light crews will begin a project to maintain the electrical reliability in Pioneer Square. Crews will excavate and replace underground electrical conduits (duct banks) and then pull in new electrical cable at vaults near South Jackson Street and First Avenue South. The work will start approximately one-half block east of First Avenue South and end at South Jackson Street’s intersection with it. The work is being done in coordination with the Center City Connector Streetcar project and will occur in three stages (see map below for details).

Map of project during Stage 1. It will last approximately 45 days and start as early as August 3.


Map of project during Stage 2. It will last approximately 30 days and is planned to start September 2017.


Map of project during Stage 3. It will last approximately 30 days and is planned to start October 2017.


Impacts and Mitigation Details:

There are no power outages expected during the course of this project.

Traffic, parking, and pedestrian impacts will occur near the work site to promote safety and accommodate equipment. Heavy equipment and trucks will be located at the work site.

Uniformed police officers will assist traffic and pedestrians, and excavated areas will be covered with steel plates during non-work hours.

Schedule and More Information:

The project’s planned start date is as early as August 3. During Stage 1, crews will work Monday to Friday from 9 a.m. to 3 p.m.

During Stages 2 and 3, planned for September and October respectively, crews will be working Saturday and Sunday from 9 a.m. to 6 p.m.

South Washington Street Infrastructure Improvement

Starting as early as August 1, 2017, Seattle City Light crews will begin a project to maintain the electrical reliability in the Pioneer Square area by connecting and repairing underground conduits. The work will start on South Washington Street west of the alley between First Avenue South and Alaskan Way South (Stage 1). At Stage 2, the work will occur in the intersection of South Washington Street and Alaskan Way South. This work will reduce the likelihood of unplanned power outages.

Map of construction work during Stage 2 of the project. Only one half of the intersection will be worked on at a time.

Impacts and Mitigation Details:

During stage one,  there will be local access only onto South Washington Street and only from 1st Avenue South.

During stage two, traffic will be reduced to one lane in both directions on Alaskan Way South and west bound only on South Washington Street. Bike lanes will be closed when crews are working on the east side of the intersection. Bicyclists will need to merge with traffic in the work zone.

In both stage one and two, in order to promote safety and accommodate equipment, parking will be closed from 9 a.m. to 3 p.m. week days and 9 a.m. to 6 p.m. weekends (intermittent). Two or more spaces will be taken overnight on South Washington Street to stage equipment.

Uniformed police officers will be on site during both stages and at all times to assist with local traffic, load/unload issues, and pedestrian access.

Schedule and More Information:

The project’s planned start date is as early as August 1, 2017, and is estimated to last until fall of 2017. Daily work hours are Monday to Friday, 9 a.m. to 3 p.m., and intermittent weekend work from 9 a.m. to 6 p.m.

Repairs Along I-5 to Cause Rolling Slowdowns April 25-28

Seattle City Light crews are planning emergency repair work to restring electrical wires pulled down across Interstate 5 by last Saturday’s car/pole collision at NE 125th Street. The work will impact traffic on Interstate 5. Drivers should expect delays and consider using alternate routes.

To complete the work safely, crews must intermittently stop traffic in both directions of I-5 overnight for up to three nights. Traffic may be stopped up to 25 minutes at a time between State Route 520 and NE 205th Street as crews pull power lines across the highway.

Rolling slowdown details:

  • Work will be performed Tuesday, April 25, through the morning of Friday, April 28.
  • Crews will intermittently stop traffic on I-5 between SR 520 and NE 205h Street from 11:59 p.m. to 4 a.m.
  • Washington State Patrol troopers will assist with traffic control and escort drivers through the construction zone.

If you have questions/concerns during normal work hours, City Light’s point of contact is Mark VanOss, Sr. Public Relations Specialist, at (206) 684-3279 or mark.vanoss@seattle.gov. If your question is urgent, leave a message at (206) 386-4233 and you will be contacted.

Streetlight Inspection Will Cause Rolling Slowdown on Ballard Bridge

Seattle City Light plans to inspect streetlights on the Ballard Bridge following the Seattle Department of Transportation’s seismic upgrades. The inspection is scheduled for Thursday, Dec. 17 starting at 7 p.m. and ending at 6 a.m. on Friday, Dec. 18. The location of the inspection can be found here: BallardBridgeMap

Single northbound and southbound lane closures on the bridge will be necessary. Motorists should expect rolling slowdowns in the direction of the affected lane. Only one lane at a time will be closed. Work will start in the southbound lane and end with the northbound lane. One quarter of the streetlights on the bridge will be out at a time. Spotters will assist any pedestrians and cyclists.

Inspection of the streetlight system is needed to close the construction contract and transfer ownership of the lights to Seattle City Light.
