Post 1964 Signage History Post 1964 Signage History

As defined in 1963, Route 133 ran from "Route 1 near Laguna Beach to Route 5 near Irvine.".

In 1996, Chapter 1154 extended Route 133 to terminate at Route 241. This extension came from a transfer of a portion of former Route 231.

In 2020, Chapter 126 authorized the relinquishment to the City of Laguna Beach the portion of Route 133 that is located from Route 1 to El Toro Road by adding section 433.1:

  1. . (a) Upon the commission determining that it is in the best interests of the state to do so, the commission may, upon terms and conditions it approves, relinquish to the City of Laguna Beach the portion of Route 133 that is located from Route 1 to El Toro Road if the department and the City of Laguna Beach enter into an agreement providing for that relinquishment.
  2. (b) A relinquishment under this section shall become effective on the date following the county recorder’s recordation of the relinquishment resolution containing the commission’s approval of the terms and conditions of the relinquishment.
  3. (c) On and after the effective date of the relinquishment, all of the following shall occur:
    1. (1) The relinquished portion of Route 133 shall cease to be a state highway.
    2. (2) The relinquished portion of Route 133 shall be ineligible for future adoption under Section 81.
    3. (3) The City of Laguna Beach shall ensure the continuity of traffic flow on the relinquished portion of Route 133, including, but not limited to, any traffic signal progression.
    4. (4) For the relinquished portion of Route 133, the City of Laguna Beach shall maintain signs within its jurisdiction directing motorists to the continuation of Route 133.

This route was unsigned before 1964, and was LRN 185 between Route 1 and I-5. The remainder of the current routing was not in the state highway system at that time.

Route 133 was not defined in the initial set of state signed routes in 1934.

In October 2017, the CTC approved for future consideration of funding a project, located in Orange County (12-Ora-133, PM 3.1/3.6), that proposes to extend the north and southbound acceleration lanes on Route 133 and re-align the El Toro Road westbound turn lane in the city of Laguna Beach. The project is fully funded and programmed in the 2016 SHOPP for $9,991,000. The project is estimated to begin construction in Fiscal Year 202-21. The scope, as described for the preferred alternative, is consistent with the project scope programmed by the Commission in the 2016 SHOPP.

The following project was included in the final adopted 2018 SHOPP in March 2018: PPNO 12-Orange-133 3.1/3.6. On Route 133, In Laguna Beach, from 1,700 feet south to 1,300 feet north of El Toro Road. Extend lanes in both directions. Begin Con: 2/5/2021. Total Project Cost: $12,956K.

In December 2018, the CTC approved for future consideration of funding a project located on Route 133 in Laguna Beach in Orange County. The project proposes to improve safety at the Route 133/El Toro intersection and improve drainage flow at the intersection. The project proposes to widen existing shoulders and provide bike lanes. The proposed project is estimated to cost approximately $41.1 million. This project is funded through the State Highway Operations and Protection Program (SHOPP) and the County of Orange and is currently programmed in the 2018 SHOPP for approximately $21.4 million. Construction is estimated to begin in 2021. The scope, as described for the preferred alternative, is consistent with the project scope programmed by the Commission in the 2018 SHOPP.

In February 2013, it was reported that during a highway-widening project in California’s Laguna Canyon, scientists identified several new species of early toothed baleen whales. Paleontologist Meredith Rivin of the John D. Cooper Archaeological and Paleontological Center in Fullerton, California, presented the finds at the 2013 annual meeting of AAAS. The Laguna Canyon outcrop, excavated between 2000 and 2005, turned out to be a treasure trove containing hundreds of marine mammals that lived 17 million to 19 million years ago. It included 30 cetacean skulls as well as an abundance of other ocean dwellers such as sharks. Among those finds were four newly identified species of toothed baleen whale—a type of whale that scientists thought had gone extinct 5 million years earlier.

In January 2011, the CTC relinquished right of way in the city of Irvine along Route 133 at Laguna Canyon Road, consisting of collateral facilities.

In June 2001, the CTC considered a proposal to adopt a routing for Route 133 from ORA 4.1 at Route 73 to ORA 8.1 0.3mi S of I-405. This was part of an eventual project to widen the 2-lane highway to 4-lanes. As part of this project, Route 133 was rerouted in July/August 2004. Caltrans launched the project in January 2003, focusing on a four-mile section between the San Joaquin Hills Toll Road (Route 73) and the San Diego Freeway (I-405). The road, built in the early 1900s, carries 29,000 cars a day. When construction was completed in 2006, the roadway was less curvy, have a new drainage system and have two lanes in each direction. The lanes opened fully in October 2006. The $32 million project on the northern half of the road involved rerouted around two lakes, which will eliminate flooding during the rainy season. It also has wider shoulders and a center median. Crews built four trail and wildlife crossings that will promote wildlife access between open-space areas east and west of the road. Utility lines are now underground, and there is a new bike lane. There are 29,000 cars that use the road each day in 2006; in 2020, that number will swell to 32,000 to 56,000 cars a day. The road was originally a stagecoach route.
