context_page_description: State Route 519 is a 1.14-mile-long state highway in King County, in the U.S. state of Washington. Located entirely in Seattle, the highway connects Interstate 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 closed Alaskan Way to traffic in 2012.
context_section_description: SR 519 begins as Edgar Martinez Drive, named for former Seattle Mariners Designated Hitter Edgar Martínez, in the SoDo neighborhood of Seattle. The highway begins at an intersection between Edgar Martinez Drive, the western terminus of I-90, and 4th Avenue. SR 519 travels west over BNSF Railway tracks, heading north to King Street Station, and south of T-Mobile Park before it turns north onto Dave Niehaus Way, named for former Seattle Mariners sportscaster Dave Niehaus, at an intersection with Atlantic Street. Dave Niehaus Way continues north between T-Mobile Park and CenturyLink Field to the east and SR 99 on the Alaskan Way Viaduct to the west before becoming 1st Avenue. SR 519 turns west onto Alaskan Way at the Port of Seattle on Pier 46, parallel to Elliott Bay, to end at an intersection with Yesler Way and Colman Dock at Pier 52.
  Every year, the Washington State Department of Transportation (WSDOT) conducts a series of surveys on its highways in the state to measure traffic volume. This is expressed in terms of average annual daily traffic (AADT), which is a measure of traffic volume for any average day of the year. In 2011, WSDOT calculated that between 38,000 and 102,000 vehicles per day used the highway, mostly at the Colman Dock. WSDOT has designated SR 519 as a Highway of Statewide Significance, which includes principal arterials that are needed to connect major communities in the state.
