Construction at Harrison Street to Resume in mid-January 2017

Starting in mid-January 2017, Seattle City Light will resume civil construction to install new vaults and conduit (duct bank) in the South Lake Union neighborhood. This project was previously on hold due to crew availability. The work will allow for increased electrical reliability in the surrounding area.

Stage 1: January 2017 to February 2017

  • Crews will be breaking street pavement on Harrison Street between Dexter Avenue North and 8th Avenue North to install the new electrical vault and conduit. During construction, Harrison Street will be closed to all westbound traffic from Dexter Avenue to 8th Avenue North, but open to all eastbound traffic.

Stage 2: Late February 2017 to early March 2017

  • Crews will be breaking street pavement on Harrison Street and excavating across 8th Avenue North. One lane will remain open at all times.

Stage 3: Mid-March to late April 2017

  • On Harrison Street, crews will work between 8th and 9th avenues north, Harrison Street will be closed down during work hours. Traffic will be detoured.

Stage 4: TBD

  • At a later date, crews will work at 9th Avenue North and Harrison Street.

Construction will resume with stage 1 in early to mid-January 2017 and last approximately four months. Work hours are scheduled from Monday to Friday, 9:00 a.m. to 3:00 p.m. and weekends from 9:00 a.m. to 6:00 p.m.

Customers can expect temporary parking and traffic restrictions. Traffic and pedestrian safety will be maintained by uniformed police officers. Noise is expected during daylight hours from jack hammering and heavy equipment. During construction, uniformed police officers will assist all drivers coming and going from garages located in the alleys.
Trenches will be steel plated at night and traffic will reopen outside of working hours.
