Between 1970 and 1979, State Highway 67 was realigned between Archie Moore Rd and Mussey Grade Rd. This realignment left two sections of paving with white striping intact. Most likely, the paving dates to around 1948 when State 67 was realigned around San Vicente Reservoir.
Realigned sometime in the 1930’s, the original alignment of US 99 is still visible near the intersection of Valley Blvd and Pepper Ave. Little remains of the original paving of US 99 through the Los Angeles area, so this is a special section.
Around late 2007, Valley Blvd was again realigned to better accommodate traffic at the I-10 interchange. Sections of the 1930’s paving are now sticking out from under the asphalt.
Long before the Isabella Reservoir was built in the 1950’s, State Highway 178 passed through the Kern River Valley on an alignment much different than it is today.
With the current drought, Lake Isabella is a puddle of what it used to be…but it’s amazing what the lake has hidden all these years. The lake has not been this low since 1977 and is the second lowest level since the dams were finished in 1953.
In April, I took two trips back to the areas near where the original towns of Isabella and Kernville stood before the lake covered them and their history. Unfortunately during my visit, the actual townsite of Isabella was still under several feet of water but the remains of the trees that use to shade the town are clearly visable sticking out of the lake in several photos.

In the 1950’s, a section of what is now the 15 in San Diego was built. Known then as the Wabash Freeway, it ran from Harbor Blvd to 40th St in the City Heights area. Today, it is known as the 15 freeway and has been upgraded significantly. Access to the old freeway was a bit different than today. Nile Street in North Park used to have a direct connection with the freeway. Today, Nile Street ends in a park. A section of the old ramp still exists, however, as an access to the park.
Even in heavily built up Orange County, there can still be places where old highways can be seen. One of the best examples is located in Brea Canyon, where the Orange Freeway winds its way through open and undeveloped lands between Orange and Los Angeles Counties. Before the freeway, State 57 followed Brea Canyon Road. This two-lane roadway has changed little through here and has a few interesting features.

In July 2010, I was able to go to Baja California with a friend. Part of our route traversed Federal Highway 2 (Mexico), which suffered some damage from the April 2010 quake. Hwy 2 had been repaired but the adjacent old alignment had not been. I was rather amazed at the amount of offset from this earthquake. I observed about 2′ of horizontal and about 5′ of vertical offset at the highway crossing.
In the 1930’s, Los Angeles County began construction of an additional roadway over the San Gabriel Mountains via the East Fork of the San Gabriel River. About half of the roadway, complete with with four larger bridges and a tunnel, was constructed. Work had progressed as far as “The Narrows” by 1938. However, the March 2-3, 1938 storms caused much of the roadway to be washed out. The project was then abandoned, leaving a large arch bridge stranded many miles upriver. The tunnel still exists as well, just north of the “Bridge to Nowhere”, though it has been sealed at both ends.
In the 1955, a new road building project commenced in the canyon. This new alignment would stay high above the canyon floor until it got nearer to the “Bridge to Nowhere”, allowing that earlier work to come to some use. Progress on this roadway was slow, mostly due to poor funding. Convict labor was used for most of the project, similar to many other road building efforts at the time in Los Angeles County. Two tunnels were constructed as well. These still exist and are mostly intact. This project too was cancelled in the late 1960’s, leaving another large scar in the canyon. This road is presently known as Shoemaker Canyon Road.
Today, the canyon is protected from future development through the Sheep Mountain Wilderness Area. Even without this protection, the geology of the canyon makes for a very expensive project. Maintenance would also be costly, as seen with State 39 through San Gabriel Canyon and above Crystal Lake. In time, all these structures and cuts will wash away, leaving the canyon with only bits of concrete and asphalt to show what was once here.
I took a trip recently to the Corona area to check out some of the old alignments of US 91. I had been there before, but it has been a long time. Starting from the Green River exit off of the 91 Freeway, I headed east along the south side of the freeway. Here, the roadways named Green River Road and Palisades Drive cover the pre-freeway alignment of US 91. This section is also a portion of the 1939 Prado Dam Relocation. This realignment took the highway out of the riverbed to the north and pushed it closer to the hills. A significant portion remains today relatively intact.
Near the Green River Road interchange, an abandoned portion of the roadbed is revealed by a 1939 culvert. The pavement has long since been removed. A portion of the old median, complete with curb divots, remains to the east. The best portion, however, is on Palisades Drive. This section has a fairly continuous old median, old bridges, wooden railing, and even a mile marker from Route 91. This whole section was bypassed in the early 1970’s along with a change to the 91 / 71 interchange.
In October 2008, Lake Shasta was dropping to near historic lows. I took a trip up there to hike many of the exposed alignments. I also got out in the water in my wetsuit when I needed to. The whole trip was a lot of fun. Here are the photos from that trip.
