City Light to Install Duct Bank on 1st Avenue South

Starting in early February 2018, Seattle City Light crews will be working along 1st Avenue South, between South Royal Brougham Way and Railroad Way South to install a new electrical duct bank. This work is needed to upgrade aging electrical infrastructure in the SODO neighborhood.

The attached flier and map are included for your reference (see bottom of post). Affected customers have received this information, so no action is required on your part.

This work will be done in two stages:

Stage 1: Crews will be working in the center two lanes on 1st Avenue South. Traffic will be detoured to the outside lanes going north and south.

Stage 2: Crews will transition to the west side of 1st Avenue South, occupying both southbound lanes for duct bank excavation. Southbound traffic will merge with the northbound lanes on 1st Avenue South.

Maintenance power outages are not anticipated for this work.

Work will not occur two hours before and after major Pioneer Square/South of Downtown (SODO) events.

Daily work hours are from Monday to Friday9 AM to 3 PM, and weekends from 9 AM to 6 PM
