Michael F Ballard is the author and administrator of the Southern California Regional Rocks and Roads website, https://socalregion.com, since 1995. I have been studying the geology and highway history throughout southern California for most of my life. I am also the President of the Ridge Route Preservation Organization. Founder of the Historic Highway 99 Association of California, https://historic99.org .
I’ve slowly been working on adding more pages to my Historic Bridges of Southern California section. Los Angeles County is next and is being worked on now. While the format is still a bit “fluid”, the page should be up soon. Look to the main Historic Bridges section for updates in the next couple weeks.
In the Belltown area of Riverside, CA, I found a rather interesting concrete roadway on 24th St. It appears to be a part of a former alignment of either Rubidoux Blvd, Market Street, or combination of the two. It dates to August 1931 and is in very good shape. What I found most interesting was the curve at Avalon St, which seemed to suggest its former importance as a Riverside to Colton roadway.

Why this roadway was built and when it was bypassed may remain a mystery for some time, however, it does show that you can still find old treasures like this in Southern California.
UPDATED 2021:
According the the magazine, California Highways and Public Works January-February 1948, Crestmore Road, as it was called then, was realigned under a Federal Aid contract. The construction began March 19, 1947 and was completed August 25, 1947. This work only involved the segment in Riverside County and the new alignment was paved with concrete.
