Transportation in South San Francisco evolved with the city as farms and cattle ranches became manufacturing communities, with walking trails giving way to roads, stagecoaches to cars, and fishing piers to a deep water port. In 1904, the Bayshore Cutoff of the Southern Pacific Railroad was built through Point San Bruno, giving manufacturers in the industrial area a way to distribute goods by rail. About the same time, electric passenger service began between San Francisco and San Mateo on the famed #40 streetcar line. Until the 1940s, the local South San Francisco Belt Railway connected to this line, serving passengers on West Grand Avenue by electric streetcar and heavy industry on East Grand Avenue by steam locomotive. Since the establishment of San Francisco as a Spanish settlement in 1776, immigration and urban development in the area have produced rapid change. Today the northern peninsula includes roads, an airport, CalTrain, and BART, as well as foot and bike trails, including the Greenway, a 3-mile trail linking the San Bruno and South San Francisco BART stations, along with hiking trails through developed and natural terrain near San Bruno Mountain, the Bay Trail, and Signal Hill.
