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.
