The Foothill Freeway is the name assigned to Interstate 210 (abbreviated I-210), a 'bypass' interstate about 70 miles (110 km) long located in the Greater Los Angeles metropolitan area. Bypassing central Los Angeles via a generally west to east alignment, this freeway links many of the suburban cities and communities that surround Los Angeles to its north and east. This freeway also allows access to the San Fernando Valley without having to pass through the congestion of Downtown Los Angeles.

As its name implies, its alignment is along the foothills of the San Gabriel Mountains. The freeway is not complete; there is currently a 10-mile (16 km) gap in San Bernardino County. After a lengthy hiatus, construction on the segment of the freeway between its junction with the Orange Freeway (State Route 57) in San Dimas and the Ontario Freeway (I-15) in Rancho Cucamonga was finally completed in late 2003, although that portion is presently signed as CA-210 rather than I-210. At this time, construction of the segment between Alder Avenue in Rialto and the Escondido (I-215) freeway in San Bernardino is ongoing and is expected to be completed by 2007. When completed, the freeway will provide another link between the communities of the Inland Empire and the Los Angeles area.

[edit] The route

The Foothill Freeway'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 CA-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 210. The Foothill Freeway then becomes an east-west freeway (the CA-134 number assignment is dropped east of the interchange). The freeway's alignment continues east until its junction with Interstate 15. About five miles (7.1 km) east of the interchange, the freeway ends at Alder Avenue in Rialto (as of October, 2005).

Prior to late 2003, the Foothill Freeway's 'numbered' alignment 'transferred' to what is now State Route 57 in San Dimas - although the physical alignment, as in Pasadena continued, in this case, eastward as State Route 30. Prior to late 2003, I-210's alignment was north-south after the junction in San Dimas and terminated at its intersection with the San Bernardino Freeway (I-10), the Orange Freeway (CA-57), and the Chino Valley Freeway (State Route 71) at the Kellogg Interchange complex.

However, in late 2003, a 20-mile (32 km) segment of the Foothill Freeway east of San Dimas was completed and the I-210 numbered assignment was transferred back to the east-west segment noted above, and the CA-57 number assignment replaced the I-210 number assignment.

The segment of the Foothill Freeway between its western terminus near Sylmar and what is now a southern spur in Glendora is signed as Interstate 210. (The former southern spur has since been re-signed as CA/SR-57, although it has not yet been designated as part of the Orange Freeway.) The eastern extension is signed as State Route 210 between the southern spur and the Escondido Freeway, and as CA/SR-30 from there to its eastern terminus in Mentone. Caltrans has petitioned the AASHTO, the federal body that oversees the interstate highway system, to re-sign the entire Foothill Freeway as I-210; this petition is unlikely to succeed until the eastern extension is complete.

The removal of the leg now signed as CA-57 gives I-210 an uncommon distinction: it is a 3-digit spur route that does not connect to its parent route, I-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, I-5 and I-15. A resigning of the route to an I-X05 or I-X15 designation is extremely unlikely, as this anomaly should be remedied when the plans for converting CA-30 to I-210 are completed. 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.

[edit] Construction history

Segments of Interstate 210 were constructed over a course of several decades as follows (date of completion in parenthesis):

In the fall of 1973, a bridge under construction spanning the Arroyo Seco near Devil's Gate Dam just north of the Rose Bowl in Pasadena, California collapsed, killing several workers.

[edit] Use as movie location

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 CA/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. In late August 2006, one of the shoots here was a portion of a major action sequence in the upcoming feature film "Transformers".

[edit] State law

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.[2]

[edit] Foothill Boulevard unsigned freeway

The Foothill Boulevard unsigned freeway is a small section of freeway-like city street between Oak Grove Drive and Woodbury Road in Pasadena, California. It is part of the northeast Pasadena section of Oak Grove Drive, approximately one mile south of the Jet Propulsion Laboratory.

[edit] History

Built in the 1960s as part of the new Foothill Freeway, this section was bypassed by a new bridge over Devil's Gate. Before the assignment of an Interstate Highway number, it had been part of State Route 118.

[edit] Current status

It is now the middle of three bridges that crosses Devil's Gate wash: the original, and northernmost was La Canada Ave., the roadbed of which ran over the crest of the dam, now closed to traffic; the former Foothill Blvd, the section of original freeway, now technically a city street (now signed as Oak Grove Drive); and southermost, the current routing of the Foothill Freeway.

Before a 1980s renovation, the original black freeway signs remained in place. Currently, a number of freeway-style "exit" signs remain in place at the Arroyo Boulevard overpass.

[edit] New section opening summer of 2007

The section between the Interstate 15 and Interstate 215 are expected to open as summer of 2007. During this time the California State Highway 210 and California State Highway 30 will change out the green shields with Interstate 210 to reconnect the Interstate 10.
