Interstate 210 (abbreviated I-210, and colloquially referred to as The 210 or the two-ten) is a bypass interstate highway in the Greater Los Angeles Area of Southern California that links many of the suburban cities and communities that surround Los Angeles to its north and east. Known as the Foothill Freeway, it runs along the foothills of the San Gabriel Mountains from the San Fernando Valley to La Verne without having to pass through the congestion of Downtown Los Angeles.

East of Glendora, the Foothill Freeway is presently signed as State Route 210 (SR 210), with Caltrans (California's Department of Transportation) hoping to get it approved to become a non-chargeable interstate route. With the July 2007 completion of the freeway segment of SR 210 between Alder Avenue in Rialto and the Barstow Freeway (Interstate 215) in San Bernardino, the Foothill Freeway now provides another link between the communities of the Inland Empire and the Los Angeles area.

I-210's western terminus is at its junction with the Golden State Freeway (I-5), near the Sylmar district of Los Angeles, in the foothills separating the San Fernando and Santa Clarita valleys. From that point, the freeway's alignment is generally diagonal as it heads southeast through the northeastern San Fernando Valley and the Crescenta Valley before turning due south towards the junction with the Ventura Freeway (State Route 134) in Pasadena. At this interchange, the number assignment of I-210, somewhat confusingly, 'transfers' to the alignment of SR 134. The physical alignment of the freeway continues south, however, ending at California Boulevard; this confusing alignment is actually the unsigned northern stub of the unfinished I-710, intended to junction with the Foothill Freeway. I-210 then becomes an east-west freeway (the SR 134 number assignment is dropped east of the interchange) to the Orange Freeway (State Route 57) in San Dimas.

The Foothill Freeway's alignment continues east as State Route 210 past its junctions with Interstate 15 in Rialto and Interstate 215 in San Bernardino to Interstate 10 in Redlands.

On the above map, Interstate 210 is highlighted in red. A portion of the freeway is signed as State Route 210, highlighted in green while another segment is signed State Route 30, highlighted in orange. It is likely that all segments will signed as an interstate in the future.

Legal Definition of Route 210: California Streets and Highways Code, Chapter 2, Article 3, Section 510

Route 210 is part of the Scenic Highway System, as stated by section 263.8 of the California State Highway Code.

Route 210 from Route 5 to Route 10 in Redlands is known as the Foothill Freeway, as named by Senate Concurrent Resolution 29, Chapter 128 in 1991.^[1]

The alignment of I-210 originally included the northern segment of what is now the Orange Freeway (State Route 57) from Glendora to its intersection with the San Bernardino Freeway (I-10) and the Chino Valley Freeway (State Route 71) at the Kellogg Interchange complex in Pomona. The Foothill Freeway began construction in 1958, and the first section was opened in 1966 signed as State Route 118. The section east of State Route 134 to Interstate 10 was done in 1971.

For the next several decades, Caltrans constructed extensions to the Foothill Freeway from San Dimas to the Interstate 215/State Route 30 interchange in San Bernardino. In 2003, the 20-mile (32 km) segment east of San Dimas was completed, and the I-210 numbered assignment to the Kellogg Interchange was transferred to the current east-west segment noted above, and the State Route 57 number assignment was re-routed to its present alignment. The section between Interstate 15 and Interstate 215 officially opened on July 24, 2007.

Caltrans has petitioned the AASHTO, the federal body that oversees the interstate highway system, to re-sign the entire Foothill Freeway, including the entire segments of State Routes 210 and 30 to I-210. In the meantime, Caltrans is in the process of re-signing State Route 30 from I-215 to Interstate 10 in Redlands as part of State Route 210.

The removal of the leg now signed as the 57 gave I-210 an uncommon distinction: it is a 3-digit spur route that does not connect to its parent route, Interstate 10. Moreover, the continued lack of I-710 completion means that I-210 does not even connect to another spur route of its parent (another I-X10, for example), but rather to those of two other interstates entirely, Interstates 5 and 15. A resigning of the route to an I-X05 or I-X15 designation is extremely unlikely, as this anomaly should be remedied once Caltrans gets approval to resign the entire Foothill Freeway as I-210.

In 1974, Universal Studios used condemned houses ready to be bulldozed for a section of the freeway in Pasadena for the disaster film Earthquake.

From 1975 to 1981, the uncompleted section of Interstate 210 in La Crescenta (and the intersecting SR 2 Glendale Freeway) was often used often as a filming location. Some films and television shows filmed on this section include the theatrical films Death Race 2000, Corvette Summer and The Gumball Rally as well as the made for television films "Smash Up on Interstate 5" and "The Great American Traffic Jam."

Perhaps most famously, the American television series "CHiPs" made extensive use of the Interstate 210–CA SR 118 interchange, often conducting major action sequences on the closed freeway. This section was finally opened in 1981 once the Tujunga Wash bridge was completed.

Later, as the freeway extended further east, so did its use as a filming location. In 2005 and 2006, for example, several television shows, commercials, and feature films shot on the unopened section of the freeway between Alder Avenue and Linden Avenue in the city of Rialto. A character in the fifth season of the fictional television show 24, which is set in Southern California sometime around 2009 or 2010, gives her location to be the intersection of I-210 and I-10, presumably referring to a future reconnection of I-210 to its parent.

In late August 2006, one of the shoots on the freeway was a portion of a major action sequence in the feature film "Transformers". The 2007 series Drive, which uses highways settings for many of its action scenes, also shoots on the 210.^[2] In the first episode, the Alder Avenue exit sign is clearly legible.

The entire route is in Los Angeles County.
