California State Route 57

California 57 is the Orange Freeway. Starting at the Orange Crush interchange (Interstate 5 and California 22) at the corner of Santa Ana, Orange, and Anaheim, the California 57 freeway travels almost due north past Fullerton on its way to Diamond Bar and Pomona, passing through the Kellogg Interchange (Interstate 10 and California 71), ending at Interstate 210 (Foothill Freeway) in San Dimas and Glendora.

Originally, the path of California 57 was Pomona Avenue and Brea Canyon Road. The freeway was constructed in phases to connect Anaheim with Pomona. In the early 2000s, California 57 was extended north past the Kellogg Interchange to end at Interstate 210 due to the extension of that freeway east to Rancho Cucamonga.

Key Opening Dates of California 57 freeway sections:

Many thanks to C.J. Moon for his assistance in providing this historical chronology.

Legislatively, California 57 is proposed for extension south through Santa Ana to a terminus at Interstate 405 in Fountain Valley. Discussions in the considered constructing the freeway as a toll road, perhaps by traveling on top of or alongside the Santa Ana River. An Orange County Register article from April 2009 stated, "Two of the alternatives to be studied call for digging up the Santa Ana River and putting in freeway lanes beneath the channel, allowing for it to continue to be used for flood control. One alternative calls for a double-bore underground tunnel, though one not necessarily following the alignment of the river. A final alternative calls for an arterial road to be built above the river, at the level of the 14 existing bridges that carry surface streets along the waterway." 2

Four alternatives for a California 57 south extension were studied in mid 2009. All four were labeled "D" as part of a possible five-part strategy for reducing congestion within the central area of Orange County. The five strategies included several strategies, including intelligent transportation systems, improvements to the existing freeway network, interchange improvements, bus rapid transit, arterial improvements, and HOT lanes. One of the possible alternatives studied was the extension of California 57, which could have taken the following forms:3

A study from October 2009 determined that the tunnel and arterial options were not feasible given cost, rights of way, and environmental concerns. The tunnel option in particular would be a very expensive proposition. Given these concerns, the proposed extension of California 57 is not imminent although may be studied further in the future.3, 4

The proposed extension of California 57 is very controversial. Environmental impacts with the Santa Ana River are significant, as are cost impacts due to the elevated nature of the proposed freeway. The city of Fountain Valley is opposed to the extension for fear of impacts to already congested traffic during commuting hours on Interstate 405. Other improvements to existing roadways are planned to facilitate traffic management in central Orange County rather than focusing on this new highway proposal.2

Additional lanes and related improvements were scheduled for California 57 north. Between Fall 2010 and 2014, construction was anticipated along two segments to add lanes and improve interchanges. Segment 1 was from north of California 91 near Orangethorpe Avenue in Placentia to Lambert Road in Brea. Segment 2, which is slated to start in Summer 2011, brought improvements to California 57 between Katella Avenue and Lincoln Avenue in Anaheim.5

Improvements were also underway in Diamond Bar at the California 57 and California 60 merge, including the direct connection ramp for High Occupancy Vehicle (Carpool) traffic. Specific improvements included development of collector distributor lanes, traffic separation for the connections to Grand Avenue that eliminate weaving and merging across multiple lanes, and expanding the number of lanes. The project (planning, environmental review, design, and construction) was expected to continue from 2009 through 2016.6

California State Route 57 North
California 57 begins at the Orange Crush interchange, which is the confluence of Interstate 5 (Santa Ana Freeway), California 22 (Garden Grove Freeway), and California 57 (Orange Freeway). Ramps from Interstate 5 and California 22 merge to form the nascent freeway, which begins its journey north through Orange, Fullerton, Brea, Diamond Bar, and San Dimas before ending at Interstate 210/California 210 at the southeastern corner of Glendora. California 57 enters the city of Orange, population 128,821 as of the 2000 Census. As an alternative to Interstate 5, motorists may use California 57 north to Interstate 210 west. Although longer, the route avoids most Los Angeles-area bottlenecks and is not as heavily traveled as Interstate 405 (San Diego Freeway).

This mileage sign along California 57 (Orange Freeway) north provides the distance to Exit 16, California 60 (Pomona Freeway) west and Exit 24B, Grand Avenue. This sign still shows California 60 as the "Pomona Freeway."

Shortly thereafter, northbound California 57 meets Exit 16, California 60 west. The pull through sign advises that the left lanes continue as California 57 north and California 60 east. The original porcelain enamel sign was replaced between 2005 and 2007; it was altered to include the direct connection for carpool traffic (left lane). Through traffic on California 57 is advised to take the main lanes rather than the carpool lanes, since the carpool lanes only connect to California 60 east (as of 2007).

The forthcoming Kellogg Interchange joins SR 57 with I-10 (San Bernardino Freeway) and SR 71 (Chino Hills Freeway). Until 2002, SR 57 ended at this interchange, and I-210 took over the Orange Freeway from here to former SR 30. With the extension of SR 210 east to San Bernardino, SR 57 was extended for approximately four miles to I-210/SR 210 (Foothill Freeway).

The Kellogg Interchange, built in 1972, is the point where California 57 (Orange Freeway), Interstate 10 (San Bernardino Freeway), and California 71 (Chino Valley Freeway) come together. This interchange is named for the old Kellogg Ranch, which predates the construction of the freeway interchange and the nearby residential and commercial development. After passing under Temple Avenue, California 57 curves north to pass on the top level of this symmetrical stack interchange. Direct access, high-speed ramps connect California 57 with both directions of Interstate 10, but no access is provided to California 71 south as it is considered to be an illogical connection.

The maze of ramps associated with the massive Kellogg Interchange is not as noticeable on northbound California 57, since the Orange Freeway serves as the top deck in the symmetrical stack interchange. However, the view of this interchange from the lowest level (Interstate 10) betrays the severe height difference between these two intersecting freeways. In addition, California 71 (which is not mentioned along northbound California 57) enters the Kellogg Interchange from the southwest, adding more ramps to the stack.
