Daly City (/deɪliː ˈsɪtiː/) is the largest city in San Mateo County, California, United States, with an estimated 2014 population of 106,094. Located immediately south of San Francisco, it is named in honor of businessman and landowner John Daly.
Daly City's highway infrastructure includes State Routes 1, 35 and 82, and Interstate 280. Interstate 280, which bisects Daly City, is a primary transportation corridor linking San Francisco with San Mateo and Santa Clara counties.
The U.S. Census Bureau has identified Daly City as among the cities with the highest transit ridership. Public transportation is provided by SamTrans, BART (at the Daly City Station and the Colma Station, which abuts the Daly City limits), and some San Francisco Muni lines. Daly City is approximately eight miles south-west of downtown San Francisco and the San Francisco International Airport is nine miles south-east of Daly City; both are easily accessible by freeway or BART. In the 1980s planning was conducted for the BART extension south from San Francisco, the first step being the Daly City Tailtrack Project, upon which turnaround project the San Francisco Airport Extension would later build.
