Work planned on: H-Frame Replacement

City Light has replaced eight outdated wooden H-Frame structures with steel monopoles and installed a new fiberoptic cable and new wires that transmit electricity on high voltage lines.

City Light crews will build duct banks across South Bangor Street in the summer of 2015. Pole installation has begun and will continue through September. Restoration and Environmental mitigation activities, such as removal of pads and accesses, wetland improvements and plant maintenance, will begin in late summer 2015 and continue for several years to ensure that improvements last.


The project will improve system safety and critical City Light communications, and increase electrical reliability for customers.


The project corridor extends from City Lights Creston-Nelson substation, located at 5300 South Bangor Street, proceeds west across Beacon Avenue South, Interstate Highway 5, the Union Pacific and Burlington Northern Santa Fe Railroads, and proceeds west to East Marginal Way South. All of this work will be within City Lights Transmission Right-of-Way and/or within City of Seattle or City of Tukwila street Right-of-Way.
