State Route 33 (SR 33) is a north–southstate highway in theU.S. state ofCalifornia. It runs north fromU.S. Route 101 inVentura through theTransverse Ranges and the western side of theSan Joaquin Valley toInterstate 5 at a point east ofTracy. SR 33 replaced part ofU.S. Route 399 in 1964 during the "great renumbering" of routes. In the unincorporated sections ofKern County it is known as theWest Side Highway. In addition, theCalifornia Legislature designated the entire Kern County portion as thePetroleum Highway in 2004. The southernmost portion in Ventura is a freeway known as theOjai Freeway, while it is known as theMaricopa Highway fromOjai toMaricopa.
State Route 33 begins inVentura as a shortfreeway ("Ojai Freeway"). SR 33 then continues north as Maricopa Highway, an undivided surface road, throughOjai, followingMatilija Canyon past the easternmost extremity of theSanta Ynez Mountains inLos Padres National Forest, and passing over theTransverse Ranges at Pine Mountain Summit. As SR 33 comes down into the Cuyama Valley, it comes up to a junction withSR 166 east ofCuyama. Route 33 continues with Route 166 as they enterKern County for about 20 miles (32 km) toMaricopa where the routes separate. In Maricopa, Route 33 turns northwest, following the western side of theSan Joaquin Valley. BetweenTaft andAvenal it roughly parallelsInterstate 5 and the eastern foothills of theTemblor andDiablo ranges; for the first 15 miles (24 km) of the portion following the axis of theMidway-Sunset Oil Field. Northwest of Avenal, it turns due west to enterCoalinga. It then runsconcurrent withSR 198 and turns northeast through theAnticline Ridge. It soon becomesconcurrent with I-5 for 13 miles (21 km). Thereafter, it departs due north nearCantua Creek, turns northwest atMendota, throughFirebaugh and meetsState Route 152 inDos Palos, in which it runs concurrently due west for approximately ten miles. It departs again west ofLos Banos, turning north toSanta Nella (where it has an interchange with I-5), and roughly parallels I-5 and theSan Joaquin River until its northern terminus at I-5 and Bird Road southeast of Tracy.
When passing through the Avenal/Coalinga area travelers pass near a series of prisons and government facilities. They include:Avenal State Prison,Pleasant Valley State Prison, and theCoalinga State Hospital.
In the portions of the route inKern andFresno Counties, SR 33 passes through one of the United States' largestpetroleum extraction fields, with hundreds of nodding oil pumps along the highway. Some of the fields visible from the highway include the Midway-Sunset,South andNorth Belridge,Cymric,McKittrick,Lost Hills, andCoalinga oil fields.
Most of SR 33's route passes through sparsely populated, relatively desolate portions of the San Joaquin Valley. Travelers along it should use caution, since emergency services are typically dozens of miles away. Carrying extra water and coolant is especially advised, since summertime temperatures in the area routinely surpass 100 °F (38 °C).
Several segments of this route are part of theCalifornia Freeway and Expressway System,[2] but only two segments, one south of the northern city limits of Ojai, and one near SR 152 are part of theNational Highway System,[3] a network of highways that are considered essential to the country's economy, defense, and mobility by theFederal Highway Administration.[4] Several segments are eligible to be included in theState Scenic Highway System;[5] however, only the portion from 6.4 miles north of theSR 150 junction to the Ventura–Santa Barbara county line is a scenic highway as designated byCaltrans,[6] meaning that it is a substantial section of highway passing through a "memorable landscape" with no "visual intrusions", where the potential designation has gained popular favor with the community.[7] This scenic segment is also designated as part of theJacinto Reyes Scenic Byway, aNational Forest Scenic Byway.[8]

Before the US 399 designation was deleted in 1964, SR 33 followedSR 166 east fromUS 99 atWheeler Ridge toMaricopa in lieu of the segment from Ventura to Maricopa, and followed the old US highway from Taft to Maricopa. Today, SR 166 remains on the segment between Wheeler Ridge and Maricopa.
SR 33 used to extend north toInterstate 205 in Tracy, but this segment was relinquished after the segment of Interstate 5 from SR 33 to I-205 was completed.
When Caltrans implemented itsexit numbering program in 2002, SR 33's section of the Ojai Freeway was not included and is one of the very few stretches of freeway in California to not feature exit numbers.
Except where prefixed with a letter,postmiles were measured on the road as it was in1964, based on the alignment that existed at the time, and do not necessarily reflect current mileage. R reflects a realignment in the route since then, M indicates a second realignment, L refers to an overlap due to a correction or change, and T indicates postmiles classified as temporary (for a full list of prefixes, seeCalifornia postmile § Official postmile definitions).[1] Segments that remain unconstructed or have been relinquished to local control may be omitted. The numbers reset at county lines; the start and end postmiles in each county are given in the county column. All exits are unnumbered.
