SR 519 was added to the state highway system effective April 1, 1992. SR 519 begins at Colman Dock (Pier 52) in Seattle, and heads south along Alaskan Way to Royal Brougham Way, then east on Royal Brougham to 4th Ave S, then north a few hundred feet on 4th to Jct I-90, where SR 519 ends and I-90 begins. In 1994, SR 304 and SR 305 were extended east from Bremerton and Bainbridge Island via their respective ferry roues to Colman Dock, i.e. state law was explicitly changed to make the ferry routes part of these state highway routes. One could now say that SR 519 begins at Jct SR 304/SR 305. In 2001, ground was broken on a project to build an eatbound bridge over the BNSF/Amtrak railroad tracks east of Safeco Field. When completed in 2003, this bridge will carry eastbound SR 519 along Atlantic St to 4th Ave S. The west end of I-90 will be modified to meet SR 519/4th Ave S at Atlantic. A second bridge will be built over the tracks at Royal Brougham Way between 2003 and 2005, with modifications to westbound I-90 tying into the modified SR 519. Today, SR 519 is 1.14 miles long. In my opinion, SR 519 should be renumbered as an extension of SR 304 and/or SR 305.
