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.

SR 519 was codified in 1991 as a state highway and began at the western terminus of I-90, then at 4th Avenue S., and traveled west onto Royal Brougham Way and north on Alaskan Way to Colman Dock.<ref name="RCW"/> The city streets in Seattle used by SR 519 were constructed after the series of regrades in the early 20th century filled a mudflat in SoDo.<ref name="HL-waterfront">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> By 1916, Alaskan Way (then known as Railroad Avenue) was paved and had its rails removed to handle growing traffic.<ref name="wsdot-DEIS">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name="HL-viaduct1">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The Alaskan Way Viaduct was built above Alaskan Way between 1950 and 1953 and narrowed the street after Colman Dock was transferred to Washington State Ferries in 1951.<ref name="HL-viaduct2">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name="HL-ferries">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Ferry routes were incorporated into the state highway system in 1994, as SR 304 and SR 305 were extended to Seattle and SR 339 was created.<ref name="law1994">Template:Cite book</ref>
WSDOT completed their South Seattle Intermodal Access Project in May 2010, which improved SR 519 and the western terminus of I-90 to better handle freight traffic heading to the Port of Seattle. New bridges over BNSF Railway tracks were built on Royal Brougham Way and off-ramps to I-90 that connect to Edgar Martinez Drive. SR 519 was later moved onto Edgar Martinez Drive in 2010 as a direct extension of I-90 after the construction of the new ramp and improvements to an intersection with Atlantic Street.<ref name="wsdot-ssiap">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name="log-2010">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Until then, SR 519 had used a section of South Royal Brougham Way and 4th Avenue South to reach the I-90 ramps.<ref>Template:Cite WSDOT map</ref> SR 519 is routed onto two streets named for Seattle Mariners personalities: Edgar Martinez Drive, dedicated in 2005,<ref name="edgar1"/> and Dave Niehaus Way, dedicated in 2010.<ref name="niehaus"/> During the construction of the Alaskan Way Viaduct replacement tunnel, WSDOT closed SR 519 and Alaskan Way between King Street and Yesler Way in May 2012, re-routing the highway to a temporary alignment.<ref name="wsdot-map2012">Template:Cite map</ref> Alaskan Way is planned to be widened to eight lanes to accommodate bus lanes and turn lanes for the ferry terminal.<ref>Template:Cite news</ref>
