The San Gabriel Valley, often referred to by its initials as SGV, is one of the principal valleys of Southern California, with the city of Los Angeles directly bordering it to the west, and occupying the vast majority of the southeastern part of Los Angeles County. Surrounding landforms and other features include the following:
The Arroyo Seco Parkway, also known as the Pasadena Freeway, is one of the oldest freeways built in the United States. The parkway connects Los Angeles with Pasadena alongside the Arroyo Seco seasonal river. It is notable not only for being an early freeway, mostly opened in 1940, but for representing the transitional phase between early parkways and later freeways. It conformed to modern standards when it was built, but is now regarded as a narrow, outdated roadway. A 1953 extension brought the south end to the Four Level Interchange in downtown Los Angeles and a connection with the rest of the freeway system.
Colorado Boulevard is a major east–west street in Southern California. It runs from Griffith Park in Los Angeles east through Glendale, the Eagle Rock section of Los Angeles, Pasadena, and Arcadia, ending in Monrovia. The full route was once various state highways but is now locally maintained in favor of the parallel Ventura Freeway and Foothill Freeway (I-210).
State Route 118 is a state highway in the U.S. state of California that runs west to east through Ventura and Los Angeles counties. It travels from State Route 126 at the eastern edge of Ventura immediately northwest of Saticoy, then through Saticoy, in Ventura County east to Interstate 210 near Lake View Terrace in Los Angeles. SR 118 crosses the Santa Susana Pass and the northern rim of the San Fernando Valley along its route.
The Foothill Freeway is a freeway in the Los Angeles metropolitan area, California, United States, running from the Sylmar district of Los Angeles east to Redlands. The western segment is signed as Interstate 210 (I-210) from its western end at I-5 to SR 57 in Glendora, while the eastern segment is signed as State Route 210 (SR 210) to its eastern terminus at I-10. Under the California Streets and Highways Code, the entire Foothill Freeway is legally referred to as Route 210.
The Arroyo Seco, meaning "dry stream" in Spanish, is a 24.9-mile-long (40.1 km) seasonal river, canyon, watershed, and cultural area in Los Angeles County, California. The area was explored by Gaspar de Portolà who named the stream Arroyo Seco as this canyon had the least water of any he had seen. During this exploration he met the Chief Hahamog-na (Hahamonga) of the Tongva Indians.
Lake Avenue is a major north–south feeder road for the Pasadena and Altadena communities in Los Angeles County, California. The road was developed in the mid 19th century and takes its name from a lake which was located at its southernmost end known variously as Mission Lake, Kewen Lake, and Wilson Lake reflecting different owners of the land. The lake bed still exists as a municipal park in the City of San Marino just south of the Raymond Dike, but it holds no water. It has been surrounded by residences who are served by a crisscross set of roads that dip into the edges of impression and back out the other side. Lake Avenue is approximately 5.06 miles (8.14 km) in length.
The A Line is a 48.5-mile (78.1 km) light rail line in Los Angeles County, California. The A Line runs east-west between Azusa and Pasadena, then north-south between Pasadena and Long Beach, via Downtown Los Angeles. The A Line is currently the longest light rail line in the world, surpassing the Coast Tram in Belgium.
The L Line and Gold Line are former designations for a section of the current Los Angeles Metro Rail system. These names referred to a single light rail line of 31 miles (50 km) providing service between Azusa and East Los Angeles via the northeastern corner of Downtown Los Angeles, serving several attractions, including Little Tokyo, Union Station, the Southwest Museum, Chinatown, and the shops of Old Pasadena. The line, formerly one of seven in the system, entered service in 2003. The L Line served 26 stations.
Foothill Boulevard is a major road in the city and county of Los Angeles, as well as an arterial road in the city and county of San Bernardino, stretching well over 60 miles (97 km) in length, with some notable breaks along the route. Like its name implies, Foothill Boulevard runs across the foothills of the San Gabriel and San Bernardino Mountains.
U.S. Route 66 is a part of a former United States Numbered Highway in the state of California that ran from the west in Santa Monica on the Pacific Ocean through Los Angeles and San Bernardino to Needles at the Arizona state line. It was truncated during the 1964 renumbering and its signage removed in 1974. The highway is now mostly replaced with several streets in Los Angeles, State Route 2 (SR 2), SR 110, SR 66, San Bernardino County Route 66 (CR 66), Interstate 15 (I-15), and I-40.
Fair Oaks Avenue in Pasadena, California, is a major north–south road connecting the communities of Altadena, Pasadena, and South Pasadena, running 7.9 miles (12.7 km) in length. It starts at its southernmost end in South Pasadena at Huntington Drive. It travels due north to a terminus above Loma Alta Avenue in Altadena and the gates of Angelus County Park. Beyond this, the road becomes a private easement.
South Pasadena Local was a local streetcar line operated by the Pacific Electric Railway between Downtown Los Angeles and South Pasadena, California by way of the Arroyo Seco Route. This was one of four lines that connected the two cities.
The Monrovia–Glendora Line was a route on the Pacific Electric Railway serving the San Gabriel Valley. It operated from 1902 to 1951, supporting nearby real estate development.
The Pasadena via Oak Knoll Line was an interurban route of the Pacific Electric Railway. It operated from 1906 until 1950, between Downtown Los Angeles and Downtown Pasadena, California. Cars ran as far as Altadena during rush hours.

The Pasadena Short Line was a passenger railway line of the Pacific Electric Railway. It ran between Downtown Los Angeles and Downtown Pasadena, California, through Eastside Los Angeles along the foot of the eastern San Rafael Hills to the western San Gabriel Valley. It was in service under the company between 1902 until 1951, though it had operated under different companies back to its beginnings as a horsecar line. The route, designated by the company as line 2, was the key component of the company's Northern Subdivision.
