The first short freeways in the Los Angeles area, the Ramona east of downtown where the 10 Freeway runs now, and the Arroyo Seco Parkway running south from Pasadena, were hugely successful experiments built beginning in the 1930s.
Their popularity fueled much enthusiasm among civic planners, who proceeded to propose a massive system of 1,500 miles of freeways in the L.A. metro area. Only a third of them ever were built.
The 91 Freeway was among them. Work on the freeway began in 1965, but it had been on the drawing boards since 1946 and received approval from the California Highway Commission in 1955. (The agency would be consolidated and renamed CALTRANS in 1973.)
Its purpose? To provide a single roadway that would link inland areas – its eastern terminus would be in Riverside – all the way west to Highway 1, the Pacific Coast Highway, in Hermosa Beach.

Did I mention that PCH was to be its western terminus? I did. In the original state highway plan, the 91 Freeway would have linked up with the proposed Pacific Coast Freeway. That roadway would have been an extension of the Ocean Freeway to be built through Santa Monica and Venice, following roughly the route that Vista del Mar currently takes along the South Bay coast.
A pretty tidy plan. Except that there was no way that coastal residents in any of the affected communities would allow either of those freeways to happen. Their serious opposition began after actual construction began on the 91.
Coastal cities banded together to denounce the plan, citing a laundry list of reasons: the high cost of land acquisition, loss of valuable beach property to the roadway, close proximity to the ocean, and limited value of the proposed roadway to north-south travelers.

According to a 1967 Palos Verdes Peninsula News story, “the citizens of South Bay communities who might be served by the freeway are presently served by both San Diego and Harbor freeways and will be served by the Hawthorne freeway and that they do not require additional freeways.”
So much for the beach idea. State highway planners removed the Pacific Coast Freeway from its master plan in April 1967.
91 Freeway construction was well underway by 1970, when let–get-real meetings began to be held for reconsidering its western terminus. After nixing its coming to their town, Hermosa Beach had recommended extending the 91 just to Hawthorne Blvd., on the route for the Torrance Freeway that had been proposed in 1965.
The Torrance City Council debated this question for the next two years. In February 1972, Councilman George Brewster was the only member to vote against a resolution opposing building both the Artesia and Torrance freeways through the city.
In 1974, the Torrance Freeway plan was finally killed by CALTRANS. By April 1974, 91 Freeway construction had been completed west through to Wilmington Ave., though its interchange with the 710 Freeway in Long Beach wouldn’t be finished until later that year.
A Los Angeles Times story suggested that the final leg of the project, now slated to terminate just west of the 110 Freeway in Gardena, would be completed by late summer 1975. That prediction turned out to be laughably optimistic.

All new freeway construction had to be halted in late 1975 due to the state’s budgetary woes and the intransigence of Gov. Jerry Brown regarding the financing of further highway work. With no highway funds left to complete it, the 91 Freeway had reached within a quarter mile of its proposed interchange with the 110 Freeway, but could go no further.
So motorists wishing to connect to the new route from the 110 were dumped onto surface streets, and had to navigate traffic signals in order to make the connection to the 91. The predictable results: a nearly nonstop traffic snarl on the roadways between the two freeways.
The situation had worsened enough by 1977 for County Supervisor Kenneth Hahn to describe the junction to the Times as “the most dangerous two-block stretch in California.” But the wheels continued to move slowly on the project.
It took another five years for construction to begin. At least it only took three more years, instead of the four originally projected, to complete work on the freeway interchange. That finally happened in June 1985, a full decade’s worth of commuter misery since work on the project had halted in 1975.

The 91 Freeway now stretches for some 56 miles, from its western terminus at Vermont Ave. in Gardena through Long Beach and Orange County, where it continues through the Santa Ana Canyon and eventually ends at the 60 Freeway in Riverside.
While not a freeway, the section of Artesia Blvd. west from Vermont to PCH in Hermosa Beach remains a part of State Route 91, though the state had returned all control of the highway to the various cities along its path by 2003.
From Gardena to the 710 Freeway, its name is the Gardena Freeway. From the 710 to the intersection with the 5 Freeway in Orange County, its name is the Artesia Freeway; from there east to its junction with the 60 Freeway in Riverside, it’s the Riverside Freeway. But for most of us, it’s just “the 91.”
