Western Terminus of US 66

Sort of correct, Santa Monica is the end, just not Santa Monica Blvd and Ocean Ave.

The west end of US 66, at least in popular culture, has always been at the Pacific Ocean, or at least close to it. Santa Monica Pier, at times, touts itself as the western end. The intersection of Ocean Blvd and Santa Monica Blvd also does the same. While both are scenic and somewhat obvious ends, they simply are not correct.

As US 66 was by California standards, a State Highway, it falls under a specific standard. All signed routes, be they a State, US, or even Interstate Highway, ran along specified roadways which were all State Highways and maintained by the State. Signage for such routes would not have been on any other roadway, for a multitude of reasons. This may seem confusing to the layperson, but it does make sense. There is, as the saying goes, method to the madness. Think of it from a legal standpoint. If a highway is signed as a State, US, or Interstate route, the layperson (generally the public) would assume it be maintained by an agency above the city it passes through. Liability for such a roadway goes to the State. If the State has no interest in the roadway, there is no reason to push this perceived liability upon it. Therefore, only roadways maintained by the State get signed. Seems simple enough.

Now, how does this pertain to the western end of US 66 you ask? Both the pier and the intersection of Ocean and Santa Monica are not State Highways nor part of a State Highway The true end of the road was at a place that was far less extravagant and scenic. The end of US 66 was at the intersection of Lincoln Blvd and Olympic Blvd, which was the junction of US 66 (Lincoln Blvd north of Olympic), US 101 Alternate (Lincoln Blvd south of Olympic), and State Highway 26 (Olympic Blvd). Today, this intersection is at Lincoln Blvd, Olympic Blvd, and the Santa Monica Freeway. The western end of Olympic was subsumed by the Santa Monica Freeway (originally to be named the Olympic Freeway) in 1965. This western end existed from 1935 until 1964, when US 66 was cut back to Los Angeles.

Eventually, US 66 was cut back even further. Initially to Downtown Los Angeles, it was further reduced as time passed, and by 1984 the route was entirely gone. Today, the highway is marked by Historic Route signs across most of its journey through the Los Angeles area.

So, when visiting the west end of US 66, do it right. Visit the intersection of Lincoln Blvd and Olympic Blvd. Any other location is incorrect. If you do visit the pier, make sure to check out their exhibit on Bob Waldmire near the west end of Pacific Park, who helped promote old US 66 with his very intricate and detailed artwork.

Original pavement remaining at Castaic Junction, CA on old US 99

Castaic Junction, located just north of Six Flags Magic Mountain in the Santa Clarita Valley was an important stop along US 99 and State 126 until the 1980’s. A Standard Oil gas station, one of the largest and busiest at the time, was located here in addition to Tip’s Restaurant. The restaurant was reported to be the last stop for James Dean before he died on September 30, 1955. A Beacon station also existed here at the south side of the junction, though it didn’t last as long as the Standard station. The gas station closed sometime in the 1980’s and the restaurant persisted as the Castaic Junction restaurant a bit longer.

A Brief History of the Roadway Changes

The roadway through the junction has also undergone many changes since it was first paved. In 1917, a 15′ concrete slab was laid down. This was widened in 1922 by adding two 2.5′ slabs on either side of the existing concrete. At the time, Castaic Junction was a “wye” intersection, with US 99 making up the east side and State 126 on the south side. The west side was a connector road from SB US 99 to WB 126. In 1931, the 1917/1922 pavement was removed and replaced with a wider two-lane section along the same route. By 1933, an additional lane was added making it a three-lane “suicide lane” setup.

In 1948, yet more changes were made to the junction. US 99 was realigned a bit to the east and made a four-lane expressway. State 126 was also widened, though just at the junction itself. The former west leg of the junction was removed as the Standard Oil gas station was augmented. This configuration lasted until 1964 when I-5 was constructed and the whole intersection was bypassed.

Today, little remains of any of the structures that existed at the junction. A new shopping center and Caltrans maintenance yard occupy the area east of the junction. The original traffic signals were replaced and additional curbs were added.

Surprisingly, the original 1917 wye junction remains nearly completely intact. The west and east legs of the junction are still visible, despite a major realignment, the construction of the Standard Oil gas station in 1948, and its subsequent demolition. How long any of this will last is unknown as development is likely to erase these traces in the near future.

Historic Sign Revealed in Los Angeles

Either through heavy wind, corrosion, or a combination of the two, a section of “greenout” fell off a sign on the eastbound Ventura Freeway (State 134) recently at Victory Blvd. This sign, approaching the Golden State Freeway (I-5) has been there since 1961 when the freeway opened. In 1961, the Golden State Freeway was still US Highway 99. In 1965, the sign was covered over with an overlay for I-5. In early 2023, that overlay (“greenout”) fell off, revealing a portion of the original signage. The left side of the sign has a State 134 EAST sign as 134 proceeded east toward Pasadena via the Golden State Freeway and Colorado St until 1968.

I-5 Grapevine / Ridge Route Conditions

Near Cherry Canyon on “The Grapevine”

I-5 between Santa Clarita and the San Joaquin Valley over Tejon Pass is known as “The Grapevine” and formerly known as “The Ridge Route”. It is an important corridor in California and has been so since 1915. Travel over the route can be quite treacherous in winter due to both rain and snow. Mudslides, rockfalls, and ice can all wreak havoc on travel. Collisions can mar traffic for miles. Caltrans, CHP, and the County of Los Angeles work together to ensure safe travel over the route. Sometimes this can result in a full closure of the pass.

To stay up-to-date on current conditions, we recommend the following sites:

Weather Forecasts from the National Weather Service:

Be safe out there and always use caution during winter months when traveling the “Grapevine”.

STATS:

Highest elevation – 4144′ at Tejon Pass

Normal Closure Points:

  • SOUTHBOUND at Grapevine (Exit 215)
  • NORTHBOUND at Castaic – Lake Hughes Road (Exit 176B)

ALTERNATE ROUTES:

If the 5 is closed, alternate adjacent routes such as Lake Hughes Road are not advisable as they may be in worse condition or be heavily congested. Depending on closures, the best alternative to I-5 is via State 14 (Antelope Valley Freeway) and State 58 over Tehachapi Pass. In times of heavy snow, your only option may well be US 101 to State 46 in Paso Robles. Check with Caltrans and CHP prior to travel to make sure these roads are open. DO NOT ALWAYS TRUST GOOGLE. It can lead you down bad or otherwise unsuitable roadways. In January 2021, multiple people including three big rigs were trapped on the Old Ridge Route during a snowstorm when they attempted to bypass a closed I-5. We don’t want you to end up on the news. Always be safe and always use caution on unfamiliar roads.

SPECIAL NOTE:

The Old Ridge Route (Ridge Route Road / 8N04) is NEVER an alternate to I-5 under any conditions and is not suitable for heavy traffic nor is it open to through traffic. It is closed to through travel from Castaic to Gorman (State 138).

From the Archives – 1953

San Diego’s Mission Valley has changed quite a bit over the last century. It has gone from farms to condos. Dairys to grocery stores. Dirt roads to major freeways. In 1947, the first iteration of the current State 163 / I-8 interchange was completed as shown here. Left on and offramps were the order of the day. Challenge Dairy’s San Diego headquarters can be seen in the upper left corner of the interchange. Additional changes to the junction took place in 1959, 1978, and 1991. All of these bridges have been replaced but their legacy remains today with the outer ramps on either side of the 8.
