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 Foothill Freeway name is a reference to Foothill Boulevard and the San Gabriel Mountains, both of which the freeway runs parallel to for most of its length. The freeway follows the foothills of these mountains, connecting the northeastern suburbs of Los Angeles with the Inland Empire. Historically, the Foothill Freeway spanned multiple numerical designations. Additionally, the I-210 designation has changed routings, previously including a portion of what is now the Orange Freeway (SR 57). East of Pasadena, the Foothill Freeway parallels, and in some parts replaced, the route of former U.S. Route 66.
The portion between I-5 and SR 259 in San Bernardino was up to Interstate Highway standards by 2007, but the eastern segment remains signed as a state route because the portion between SR 259 and I-10 had not met those standards.[3] On February 26, 2020, construction in each direction took place to complete the standards required. The three-year project added lanes from Sterling Avenue in San Bernardino to San Bernardino Avenue in Redlands. Although construction was completed in September 2023, the eastern end currently remains "Route 210".[4][5]
