According to iTypeJob, the State Route 22, SR-22 or Garden Grove Freeway is a state route and freeway in the U.S. state of California. The highway forms an east-west route in Orange County, in the southern suburbs of Los Angeles. The highway runs from Long Beach to Orange, but is a regular street in Long Beach, and is briefly double-numbered with I-405. The highway section runs from I-405 in Garden Grove to SR-55 in Orange, and is 12 miles long. The total route is 24 kilometers long.

Travel directions

SR-22 begins as a branch of Interstate 405 in Garden Grove, with an immediate intersection with Valley View Street. Garden Grove is the first city, and is directly one of the larger suburbs of Los Angeles with 170,000 inhabitants. Los Angelesitself is 35 kilometers to the northwest. The SR-22 forms more or less the division between Garden Grove on the north side and Westminster on the south side, which has 88,000 inhabitants. Garden Grove is home to a fairly large business park, enclosed on all sides by residential areas. The road network here consists of a grid model, with major streets that SR-22 intersects, such as Beach Boulevard, Brookhurst Street and Euclid Street. Southeast of Garden Grove is Santa Ana, one of the largest suburbs in Los Angeles with a population of 353,000.

In Santa Ana, the Orange Crush Interchange crosses two other freeways, Interstate 5, which runs from Los Angeles to San Diego, and State Route 57, the Orange Freeway, which begins here and runs north to San Dimas. It is one of the most complex interchanges in the United States with 3 exits incorporated into the already large interchange. The junction is also the border with Santa Ana and Orange, a suburb with 128,000 inhabitants, also a fairly large suburb. Four miles away, SR-22 ends at State Route 55, or Costa Mesa Freeway, which runs from Costa Mesa to Anaheim.


According to iTypeUSA, the number SR-22 was already assigned in 1934, when the roads in the state of California were first numbered. Before the highway was built, the route passed over Garden Grove Boulevard, which was then called Ocean Avenue. The first section opened in 1963 in Santa Ana and the highway was completed in 1967, and was one of the few highways that was not widened after opening, unlike almost all other highways, which had to be widened due to the enormous growth in the metropolitan area.. In the 1990s, this led to severe congestion, particularly due to the population growth in Santa Ana.

In late 2004, the Orange County Transportation Authority began widening SR-22 to one lane for regular traffic and one HOV lane in each direction, as well as upgrading all connectivity to modern design requirements. The funding came from a general tax hike in Orange County by half a cent. This project was completed in May 2007.

The entire Garden Grove Freeway has HOV lanes, and connects to the HOV facilities of I-405, I-5 and SR-55 and SR-57.


The HOV lanes on SR-22 were opened to traffic in 2007. Construction consisted of widening the highway to 2×5 lanes. This was the first adaptation to the road since 1967.

State Route 23 or SR-23 is a state route and partial freeway in the U.S. state of California. The highway forms the westernmost north-south route in the Los Angeles region, located 40 miles west of downtown. State Route 23 runs from Malibu to Fillmore, and is 31 miles long. The highway section is called Moorpark Freeway and is 14 kilometers long.

Travel directions

State Route 23 in the Santa Monica Mountains.

State Route 23 begins west of Malibu at an intersection with State Route 1 (Pacific Highway). The road then heads north as a single-lane road through the Santa Monica Mountains. The State Route 23 here is a winding road with nice views. The road reaches a maximum of about 550 meters above sea level before descending into the valley where the town of Thousand Oaks is located. In Thousand Oaks, State Route 23 becomes a busier 2×2 lane urban arterial, then connects to US 101.

A little further west, State Route 23 branches off from US 101 and forms a freeway of its own, the Moorpark Freeway, which runs between Thousand Oaks and Moorpark. The highway has 2×3 lanes and does not run completely through built-up areas. In Moorpark, one crosses State Route 118, which forms the freeway to Simi Valley, while State Route 23 turns off and heads north through the Santa Susana Mountains as a secondary road. In Fillmore, the road ends at State Route 126.


The number SR-23 was assigned in 1934. The highway was built mainly in 1970 and 1971, but it was not until 1993 for the Moorpark Freeway to join the Simi Valley Freeway.

In the past, there have also been plans for the so-called ‘Decker Freeway’, a highway between State Route 1 and US 101 in the corridor of State Route 23. This appeared in the highway plan of the region in 1958, but the plans were later rejected as unfeasible due to geography.

The Moorpark Freeway does not have HOV lanes, as do the connecting highways. HOV lanes are also not planned due to the relatively minor importance of the highway.
