The Great Highway is a road in San Francisco that forms the city's western edge along the Pacific coast. Built in 1929, it runs for approximately next to Ocean Beach. Its southern end is at Skyline Boulevard (State Route 35) near Lake Merced; it extends to Point Lobos Avenue and the Cliff House at its northern end. In 2020 a portion of the road was closed to vehicular traffic, opening back to traffic in 2021 during weekdays. Description The Great Highway is a four-lane divided road built in 1929 that is approximately long and runs next to the Pacific Ocean along to Ocean Beach on the west side of San Francisco. The Great Highway starts at Skyline Boulevard and runs north to Point Lobos Avenue and the Cliff House in the Outer Richmond neighborhood of San Francisco. It forms the western border of Golden Gate Park with two windmills, the Dutch Windmill and the Murphy Windmill at the northwestern and southwestern corners of the park along the highway. Both windmills were built to pump water into Golden Gate Park. As a north–south throughway, this section of the highway does not provide access to destinations in the nearby Sunset neighborhood, other than Lincoln Way and Sloat Boulevard. It is a recreational street with no car-usable turn-offs in the two miles between Lincoln and Sloat. This provides limited use for local traffic, so a parallel street named Lower Great Highway is immediately adjacent to the east of the recreational street. This street has residential dwellings on one side and a mixed use trail running parallel between the two streets. It is adorned with stop signs and speed bumps on nearly every block. The N Judah, a San Francisco Municipal Railway streetcar line, ends at Great Highway and Judah, while the L Taraval, another streetcar line, ends two blocks from Great Highway at Wawona and 46th Avenue. History The Great Highway was laid out in the Humphreys-Potter map of 1868 which laid out the streets of San Francisco’s newly acquired Outside Lands, including the Richmond and Sunset districts. In the 1890s, a railway line was run along the route of the Great Highway from its Southern terminus to Golden Gate Park in order to build the California Midwinter International Exposition of 1894. Although these tracks were removed in February 1895, the berm that supported them is still visible on the East side of
