San Dimas: SR-57 : (491) South of I-210

1 34.12°, -117.82° S
About location

San Dimas combines suburban growth with a foothill setting in a way that reflects its position at the base of the San Gabriel Mountains. State Route 57 reaches its northern end at Interstate 210 here, placing the city on a major corridor between the Inland Empire and the wider Los Angeles area. The terrain changes quickly from built-up streets and freeway infrastructure to the canyons and ridges of the range, including nearby San Dimas Canyon. Foothill Boulevard, part of historic Route 66, runs through the community and recalls the road travel that shaped Southern California before the interstate network. San Dimas is both a residential city and a practical approach to the mountain front.

City San Dimas

Built around a stop on the Atchison, Topeka and Santa Fe Railway, San Dimas grew into a Southern California foothill city. The community sits below the San Gabriel Mountains, east of the San Gabriel River corridor, where inland valleys meet mountain slopes. Citrus groves shaped its early economy, and the 1887 Walker House, a wooden Victorian residence, remains a link to the original railroad-era settlement. Downtown retains a smaller-scale character than much of metropolitan Los Angeles, while Frank G. Bonelli Regional Park and Puddingstone Reservoir are close by.

California occupies a long Pacific coastal belt in the United States. Its terrain ranges from the Sierra Nevada and the fertile Central Valley to deserts in the southeast and the rugged shores of the Pacific Ocean. The state includes both Mount Whitney, the highest point in the contiguous United States, and extensive protected lands such as Yosemite National Park. California’s cities have exerted worldwide influence through film, technology, agriculture, and music; Hollywood remains an enduring symbol of the American screen industry. Its scale means climates and local character can change dramatically from one county to the next. Continue through nearby webcams to explore different parts of California.

The Atlantic, Pacific and Gulf coasts define much of the United States — their ports, fisheries and trade routes have long tied the country’s economy to the wider world. Between them, the Rocky Mountains, Great Plains and Mississippi River basin form sharply different regions, from high western ranges to broad agricultural heartlands. Cities carry much of the national story: New York’s Statue of Liberty, a gift from France dedicated in 1886, remains an enduring symbol, while Washington, DC concentrates major federal institutions. Indigenous nations have shaped these lands for millennia, and their living cultures remain essential to the country’s identity.
