Interstate 210 and State Route 210 (California) - Route Description

Route Description

I-210's western terminus is at its junction with the Golden State Freeway (I-5), near the Sylmar district of Los Angeles. From that point, the freeway's alignment is generally diagonal as it heads southeast through the northeastern San Fernando Valley and the Crescenta Valley. After leaving Los Angeles, it enters North Glendale and meets with the Glendale Freeway (State Route 2) before turning due south towards the junction with the Ventura Freeway (State Route 134) in Pasadena. At this interchange, the Foothill Freeway shifts its alignment and direction, becoming an east-west freeway. From the north, the primary through lanes of I-210 become the unsigned northern stub of unfinished I-710, while from the east, the through lanes of the Ventura Freeway become I-210 as the Ventura Freeway reaches its official eastern terminus. After intersecting the northern terminus of I-605 (The San Gabriel River Freeway), I-210 then continues east to the Orange Freeway (State Route 57) in Glendora. Heading east from the Orange Freeway interchange, until its eastern terminus at I-10 in Redlands, 210 is currently signed as a state route.

Portions of the Metro Gold Line of the LACMTA run in the median of the Foothill Freeway from Pasadena to Arcadia.

State Route 210 presently has two distinct segments:

The western freeway segment serves as the easternmost portion of the Foothill Freeway (Interstate 210). Consisting of newer freeway, beginning at the east end of I-210 near San Dimas, SR 210 extends eastward, eventually paralleling Highland Avenue, as it continues through Fontana. It intersects Interstate 15, an artery between Southern California and Nevada a few miles before it meets with Interstate 215 in San Bernardino.

The segment east of Interstate 215 is the former alignment of State Route 30. This segment extends eastward to junctions with Interstate 215, State Route 259, State Route 18 and State Route 330 in Highland. State Route 210 then curves southward and ends in a junction with Interstate 10 in Redlands.

The Glendora Curve is the former colloquial name for the interchange between State Route 57 and the Foothill Freeway, Interstate 210. The "curve" portion refers to the interchange from the northbound lanes of State Route 57 to the westbound lanes of I-210, and from the eastbound lanes of I-210 to the southbound lanes of State Route 57. The origin of the name comes from its location in the city of Glendora. Prior to 2002, this interchange was entirely part of I-210, and the eastern terminus of I-210 ended several miles south of the curve at the Kellogg Interchange at the junctions of the Chino Valley Freeway, State Route 71, the San Bernardino Freeway, I-10, and Route 57. After the portion of I-210 south of the Glendora Curve was transferred to Route 57 in 2002, effectively extending Route 210 east past the Glendora Curve, the name Glendora Curve fell out of popular use.

This route is part of the California Freeway and Expressway System and is eligible for the State Scenic Highway System.

Famous quotes containing the words route and/or description:

    The route through childhood is shaped by many forces, and it differs for each of us. Our biological inheritance, the temperament with which we are born, the care we receive, our family relationships, the place where we grow up, the schools we attend, the culture in which we participate, and the historical period in which we live—all these affect the paths we take through childhood and condition the remainder of our lives.
    Robert H. Wozniak (20th century)

    The type of fig leaf which each culture employs to cover its social taboos offers a twofold description of its morality. It reveals that certain unacknowledged behavior exists and it suggests the form that such behavior takes.
    Freda Adler (b. 1934)
