State Route 210 is a state highway in Southern California that serves as the easternmost portion of the Foothill Freeway, connecting the communities of the Inland Empire with the Los Angeles area. The eastern portion of State Route 210 was originally signed as State Route 30.

Route description

State Route 210 presently has two distinct segments:

The western freeway segment serves as the easternmost portion of the Foothill Freeway (Interstate 210). 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, although Caltrans has not yet changed all the signs on this portion to SR 210. 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.

History

File:Sb i-210Fway.jpg

San Bernardino I-210 Fwy.

The western freeway segment, planned since the 1970s and completed in 2002, replaced a western surface street segment that began with Base Line Road (sometimes spelled Baseline Road) at its intersection with Foothill Boulevard in San Dimas and extends eastward into Upland. In Upland it became 16th Street, then turned northward onto Mountain Avenue, then turned eastward onto 19th Street. It left Upland and continued eastward into Rancho Cucamonga. It then seemed to turn northward onto Haven Avenue and end at the western freeway segment. This segment is probably still signed as SR 30—at least in some places if not ubiquitously—but some recently published maps are reflecting a signage change.

State Route 30 is the former designation of State Route 210 and State Route 330. Route 30 ran from its interchange with I-210 at the Glendora Curve east to State Route 18 at Big Bear Lake. The easternmost portion of Route 30 was transferred to Route 330 in 1972. Thereafter, Route 30 was routed south to I-10 in Redlands. In 1999, the entirety of Route 30 from the Glendora Curve to Redlands was transferred to Route 210. However, the freeway portion of former Route 30 from I-215 to I-10 and portions of Highland Avenue in the cities of San Bernardino and Rialto are still signed as Route 30.

Future

With the completion of a central freeway segment in July of 2007, Caltrans is expected to ask the AASHTO to designate the entire route as part of Interstate 210. Once approved, the SR 210 and SR 30 green State Route signs will be replaced with Interstate 210 ones.

State law

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.

Exit list

Exit numbers are derived from Cal-NExUS. Postmiles along the eastern segment from Highland Avenue in San Bernardino to I-15 are currently still based on the SR 30 routing.
