State highway in King County, Washington, US
State Route 519 (SR 519) is a state highway in Seattle, Washington, United States. It connects Interstate 90 (I-90) to the Port of Seattle and Colman Dock, which serves as the terminus of two ferry routes. The highway travels along city streets, including two named for Seattle Mariners personalities: Edgar Martinez Drive and Dave Niehaus Way, as well as Alaskan Way. SR 519 was established in 1991 on preexisting streets that were first built in the early 20th century. State projects moved the southern terminus of SR 519 in 2010 to its current location and temporarily rerouted it during demolition of the Alaskan Way Viaduct.
