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.

My contribution to the Los Angeles Metro Rail System

Before the Metro Gold Line Eastside Extension was opened, I was contacted by Nobuho Nagasawa. She was commissioned to create the artwork for the 1st St and Soto St Metro Gold Line station. She was looking for maps of the area surrounding the 1st / Soto station and found my website on the East Los Angeles Interchange. After searching my collection, I did find two maps that covered that area. The Los Angeles and Alhambra 6′ map sheets from the late 1920’s covered the area she needed with the right resolution. They were then scanned in at high resolution and sent along to her for use. As they were USGS maps, they were within the public domain and easy to transfer.

As I had obtained the maps from a geologist that had marked them up, cleaning them up prior to scanning was essential. I got most of the marks off, but some still remained. It seems they were just enough to “watermark” the maps as indeed from my collection. While not intentional, it did help me identify the maps when I saw them in a video on the opening of the line. In December 2009, I was finally able to see the station in person. The sheer size of the artwork created from these maps was astounding. A portion of a 6′ USGS quad sheet had been transformed into a 30′ x 60′ map going from one side of the station to the other.

I wish to thank Nobuho Nagasawa for allowing me the privilege of contributing to the Los Angeles Metro Rail system. It gives me great pleasure to know that something I have in my collection is seeing use in a way I never expected.
