ssh 1j, the predecessor to sr 513, was added to the state highway system in 1937 and traveled within the city of seattle on streets that have existed since the 19th century. madison street, which carries ssh 1j from its southern terminus at u.s. route 99 in downtown to capitol hill was built in 1864 by local judge john j. mcgilvra to connect his homestead at madison park to downtown. other streets carrying ssh 1j, including 23rd and 24th avenues towards montlake, montlake boulevard through the university district, and sand point way towards sand point were built during the early 1890s as the city of seattle expanded. 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.
