California State Route 153; The Supposedly Shortest State Highway

I mentioned California State Route 153 in El Dorado County on the CA 49 blog but I thought it was worth it's own blog entry considering the boast made on the placard about it being the "Shortest" state highway in California.


CA 153 is a 0.544 mile route from CA 49 near Coloma to the James Marshall Monument in Marshall Gold Discovery State Historic Park.


CA 153 being the the "Shortest State Highway" certainly isn't true as CA 225, CA 275, CA 283 and CA 77 are actually shorter. 

CAhighways.org list of shortest state highways

CA 153 isn't even technically the shortest signed State Highway as CA 77 is presently signed at only 0.45 miles..  But with that said, CA 153 isn't signed particularly well as there is nothing to indicate there is an actual highway junction at CA 49 at the beginning of the route at Cold Springs Road.  CA 153 begins on the left in the pictures below.



CA 153 turns off of Cold Springs Road on to Monument Road on the right in the picture below.  Again, there is no indication that CA 153 actually exists due to the lack of signage.


Even most of Monument Road lacks any real indication that you're on CA 153.


Which changes with this lone CA 153 shield which might be the rarest ever posted in California.



CA 153 ends at the Marshall Monument which is dedicated to the finding of gold in the waters of the South Fork American River which spurred the 1849 California Gold Rush.  CA 153 was a 1964 renumbering of Legislative Route Number 92 which was adopted which was adopted in 1933.

The change from LRN 92 to CA 153 actually is observable on the 1963 and 1964 State Highway Maps.



It appears that at least up until the 1990s CA 153 wasn't actually signed in the field.  The shield must have been a rogue placement by Caltrans District 3 as CA 153 isn't shown as signed on the 1990 State Highway Map



The 1935 California Division of Highways Map of El Dorado County actually shows LRN 92 branching off from CA 49 to Marshall's Monument.

Did Caltrans just kill the G26 cutout US Route shields?

The US Route System was formally created by the American Association of State Highway Officials during November 1926.  Through the history of the system the only state to which has elected to maintain cutout US Route shields has been California.  The G26 series cutout US Route shields have become a favorite in the road enthusiast hobby and are generally considered to be much more visually pleasing than the standard Federal Highway Administration variant.  However, the G26 shield series appears to have been killed off on January 18, 2026, when Caltrans updated their Manual of Uniform Traffic Control Devices.  This blog will examine the history of the US Route shield specifications in California and what is happening with the 2026 changes.  The blog cover photo is facing towards the terminus of California State Route 136 and at a G26-2 specification US Route 395 shield.  In the background Mount Whitney can be seen in the Sierra Nevada range.   ...

May 2023 Ontario Trip (Part 3 of 3)

  Over the years, I have made plenty of trips to Ontario, crisscrossing the southern, central and eastern parts of the province. Living in Upstate New York, it's pretty easy to visit our neighbor to the north, or is that our neighbor to the west? Ottawa is one of my favorite cities to visit anywhere in the world, plus I've discovered the charm of Kingston, the waterfalls of Hamilton (which is on the same Niagara Escarpment that brings us Niagara Falls), the sheer beauty of the Bruce Peninsula, and more. But I hadn't explored much of Cottage Country. So I decided to change that, and what better time to go than over Memorial Day weekend, when the daylight is long and I have an extra day to explore. On the third and final day of my trip, I started in Huntsville and made my way through Muskoka District and Haliburton County, passing by many lakes along the way. I stopped in towns such as Dorset, Haliburton and Bancroft before making a beeline down to Belleville and then over th...

Ghost Town Tuesday; Nichols, FL

A couple years ago I spent a lot of spare time exploring phosphate mining ghost towns in the Bone Valley of Polk County, Florida.  One ghost town in particular called Nichols on Polk County Route 676 west of Mulberry caught my eye due to a relative lack of documentation on ghosttowns.com. Nichols was created in 1905 during the early phosphate mining boom in the Bone Valley region.  For the time Nichols was unusual since it had company housing in the Nichols Mine site and private residences outside the gate.  Nichols is only about two miles west of Mulberry which probably made it a somewhat reasonable commute even by the wonky standards of the early 20th Century.  Most of the Bone Valley region was relatively remote which made commuting or homesteading impractical which is why there are so many ghost towns in the area.  The company housing section of Nichols was phased out and abandoned by 1950. The Nichols town site is largely abandoned and could "possibl...
