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.

On Sunday, February 24, 2012, I went out for a ride to Campo on my motorcycle. I wanted to take some photos of the old sections of Hwy 94 and the weather was great for a ride. Starting out, it was a quick freeway ride to Campo Junction, where the two lane portion of Hwy 94 starts. That is where the fun begins. It was also where the first stop was, at the 1929 Sweetwater River bridge.

After I left the bridge, my next stop was at a section of old concrete I had discovered on a previous ride. With a camera in hand, it was time to get photos and explore some more. I didn’t find any date stamps, but I did find lots of old striping. Still pretty cool.

After Jamul, there was an old creek crossing with concrete I had found recently. It appears to be an Arizona type crossing instead of a culvert. The new crossing is now a culvert. I’m not sure its age, but I’m going to guess it is from the 1930’s. Also in the area is a neat bridge crossing Dulzura Creek at Otay Lakes Road. It was built in 1947 and has a nice sleek look.

In Dulzura, I stopped at a 1930 bridge which had bridge abutments near it from an even older span. I couldn’t quite tell what sort of a bridge the original one was, but was most likely wooden.

Further up the road at Cottonwood Creek, there are a few items of interest. The “new” Cottonwood Creek bridge from 1954 bypassed both the original bridge and large section of the alignment. Barrett Smith Road follows the old alignment up the steep grade out of Barrett Junction.

At Dogpatch, Hwy 94 crosses the San Diego and Arizona Railroad for the first time under a 1915 bridge. Just after that bridge, there is another 1947 bridge. Adjacent to the 1947 span, there are abutments to an earlier bridge.

My last stop was Campo. I needed to fuel up and get photos of the bridge at Campo Creek. It is the last bridge with wooden railing on Hwy 94. After I stopped here, I headed back to town on Hwy 94. I enjoyed the ride and the scenery. It was the first time in a long time that I had stopped so many times on 94. The last few trips have been just riding or driving.
