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.

Road Building in San Gabriel Canyon
In the early 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. The road, then known as the Camp Bonita – Prairie Fork Road, was about half complete with with four larger bridges and a tunnel, by early 1938. 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, first known as East Fork Road, then Shoemaker Canyon Road. 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 1976 , 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.
Following old US 91 near Corona
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.
Mystery bridge over the San Jacinto River
On Sunday, June 16, I went on a motorcycle ride out toward Palm Springs. On Hwy 74 just east of Hemet, I stopped to inspect an abandoned concrete arch bridge to the side of the current bridge. The “new” span, where Hwy 74 crosses today, was built in 1929. This makes the abandoned span most likely from the 1910’s. It appears to have been longer, though the rest is long since washed away. I originally saw this bridge on a previous motorcycle ride, having missed it on every driving trip through here. It just goes to show that you see more on two wheels – be they motorcycle or bicycle wheels.




After leaving the bridge, I headed east on Hwy 74 up into the mountains. The roadway was recently repaved, which was badly needed. The new pavement was quite fun to ride, even with the extra twisty passing areas. The tires seemed to grip the road better allowing me to ride faster than I did before. I didn’t originally plan to go all the way to Palm Springs, but somehow I decided “Why Not?” and did it anyway. It was rather hot while I was there, so I didn’t stay long. Leaving town was almost as difficult as dealing with the heat. Strong west winds, typical for the area, were blowing and made riding somewhat unnerving at times. The winds finally subsided once I got to the Beaumont area and temperatures decreased quite a bit as well.
US 99 in Lake Shasta – October 2008
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.
