Seattle City Light crews recently completed civil construction work on East Denny Way between Harvard Avenue and Broadway on Capitol Hill. The work will improve electric service reliability and will help to reduce the number of unplanned outages in the area. 

City Light’s construction work began June 16, 2014, and was completed on schedule two weeks later. Crews trenched and installed conduit between an existing underground electrical vault located in the sidewalk and a utility pole roughly 20 feet away. The excavation and conduit installation were the first steps to increase electrical capacity from 4 kilovolts to 26 kilovolts to customers in the area. Crews have also restored the asphalt and concrete affected by the trenching and conduit installation.

The construction and related upgrades are important to improving the electrical service reliability to City Light customers and are a vital component of the utility’s Strategic Plan.

At a later date, crews will install new electrical cable. The cable installation will take several days to complete.
