Many people only think of the SR 99 Alaskan Way Viaduct's downtown waterfront section in Seattle, but the double-deck structure extends to South Holgate Street past Safeco Field. The viaduct's south end section accounts for almost half of the entire structure.

Construction to replace the south end of the viaduct started in summer 2010. We will replace it with a new side-by-side roadway that meets current seismic standards.
