Traffic Impact Map for Phase 2 of H-Frame Project Construction work continues as City Light works to increase the electrical capacity and reliability to the Duwamish Valley with the H-Frame Replacement and Feeder Installation Project. City Light is replacing eight outdated H-Frame structures and cables that transmit electricity on high voltage lines across I-5 due to their age and increasing electricity demand. The project will improve system safety and increase electrical reliability for customers.
This phase of the project will close southbound Martin Luther King Jr Way S/SR900 at Boeing Access Road and the southbound I-5 on ramp south of Boeing Access Road as workers install a steel pole on the west side of I-5 (between I-5 and the railroads) south of Boeing Access Road.
On 9/13 (Saturday into Sunday), construction work will occur during the hours of 11 p.m. and 8 a.m. On 9/14 (Sunday into Monday) and 9/15 (Monday into Tuesday), construction work will occur during the hours of 10 p.m. and 5 a.m.
The traffic impacts and restrictions for this project are necessary for motorist and worker safety. Drivers are advised to carefully follow traffic detours and consider using alternate routes during construction.
