According to CITYPOPULATIONREVIEW.COM, State Route 57 or SR-57 is a state route in the U.S. state of California. SR-57 forms a north-south route in the Los Angeles Metropolitan Area, in Orange and Los Angeles County. The highway begins in Orange at the Orange Crush Interchange, and runs through several major suburbs to I-210 in San Dimas. The highway is also called Orange Freeway. The route is 39 kilometers long.

Travel directions

The highway begins at the Orange Crush Interchange, one of the largest interchanges around Los Angeles. Here one crosses Interstate 5, the Santa Ana Freeway, which runs from Los Angeles to San Diego, and SR-22, the Garden Grove Freeway, which runs from Garden Grove to Orange. Six connecting roads from these highways make up SR-57. The Orange Freeway forms the boundary between the city of Orange and the city of Anaheim here. Anaheim has 346,000 inhabitants, and Orange has 129,000 inhabitants. Parallel to the highway runs the Santa Ana River, which is canalised. The highway has 2×5 lanes, and passes by the Angel Stadium, a large stadium with a huge parking lot around it. This corridor has a large industrial estate on both sides. This section of SR-57 is very busy, with residents of the Inland Empire commuting daily to Orange and Anaheim.

On the north side of Anaheim, SR-91 intersects the Riverside Freeway, an important interchange because of the high traffic to and from the east. The highway connects Riverside to Long Beach. This leads to the town of Fullerton, which has a population of 126,000. The city is part of a 12-mile industrial estate that extends into Anaheim along SR-91. On the east side of the highway is the suburb of Placentia. The last town in Orange County is Brea, after which one crosses the uninhabited Puente Hills. One comes here in Los Angeles County, in the town of Diamond Bar. Here one crosses the SR-60, the Pomona Freeway, which are temporally double-numbered. After Diamond Bar you arrive in Pomona, a larger suburb with 161,000 inhabitants. A 4-tier interchange crosses Interstate 10, the San Bernardino Freeway, which runs from Los Angeles to Phoenix, and is one of the major east-west routes in the eastern suburbs. One eventually arrives at San Dimas, where SR-57 ends at I-210, the Foothill Freeway, which runs from Pasadena to San Bernardino.


According to ASK4BEAUTY, construction of the highway started in 1967 in Placentia. In 1969 the first section opened between Anaheim and Placentia, and then the highway was extended northward, closing the highway to San Dimas in 1972. In the 1970s, the highway was also extended southwards to I-5. The highway was completed in 1976.

There are plans to extend SR-57 to Huntington Beach over the Santa Ana River, an elevated highway to avoid massive demolitions of homes. The 18-kilometer viaducts would cost $950 million.


Between January 2011 and May 2014, a 6-kilometer northbound lane was constructed between Orangethorpe Avenue in Placentia and Lambert Avenue in Brea. Construction costs were $102 million. A 6th lane northbound between Katella Avenue and Lincoln Avenue in Anaheim was constructed between January 2012 and November 2014, 5 kilometers away. The cost was $45 million.

A large part of the Orange Freeway has HOV lanes, from the I-5 in Santa Ana to the SR-60 in Pomona over a length of almost 30 kilometers. Only the northernmost part of the highway has no HOV lanes.


The oldest portion of HOV lane is located in Orange County and opened in June 1992 between the Orange Crush Interchange from I-5 to Lambert Road in Brea, virtually the entire route through Orange County. On August 22, 1997, the rest of the HOV lanes opened from Brea to the Pomona Freeway (SR-60).
