Washington State Route 513
[7] SR 513 continues northeast along the Burke-Gilman Trail past the Seattle branch of the National Archives before the highway ends at an intersection with 65th Street west of Magnuson Park.[11][12] SSH 1J, the predecessor to SR 513, was added to the state highway system in 1937 and traveled 13.40 miles (21.57 km) within the city of Seattle on streets that have existed since the 19th century.[13][16] The rest of SSH 1J, traveling northwest from Naval Station Puget Sound at Sand Point through Lake City to US 99 on the border between Seattle and Shoreline via Roosevelt Way and 145th Street was constructed by the late 1800s to serve the University of Washington campus, site of the Alaska–Yukon–Pacific Exposition in 1909.[17][18][19] SSH 1J was replaced by SR 513 during the 1964 state highway renumbering and codified in 1970 on its original route, connecting Downtown Seattle to Montlake and Lake City.[2][22][23] The highway was further shortened, to its present length of 3.35 miles (5.39 km),[1] in 1991 by moving its northern terminus from I-5 to Magnuson Park at the site of the former Naval Station Puget Sound.
