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.

CAhighways.org on CA 153

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.

Interstate 40's Tumultuous Ride Through the Pigeon River Gorge

In the nearly 60 years Interstate 40 has been open to traffic through the Pigeon River Gorge in the mountains of Western North Carolina, it has been troubled by frequent rockslides and damaging flooding, which has seen the over 30-mile stretch through North Carolina and Tennessee closed for months at a time. Most recently, excessive rainfall from Hurricane Helene in September 2024 saw sections of Interstate 40 wash away into a raging Pigeon River. While the physical troubles of Interstate 40 are well known, how I-40 came to be through the area is a tale of its own. Interstate 40 West through Haywood County near mile marker 10. I-40's route through the Pigeon River Gorge dates to local political squabbles in the 1940s and a state highway law written in 1921. A small note appeared in the July 28, 1945, Asheville Times. It read that the North Carolina State Highway Commission had authorized a feasibility study of a "...water-level road down [the] Pigeon River to the Tennessee l...

Massena Center Suspension Bridge

The Massena Center Bridge, also known as the Holton D. Robinson Bridge, has had quite the tumultuous history. Situated on the Grasse River just east of Massena, New York in the hamlet of Massena Center, the Massena Center Bridge is a reminder of the efforts the community has made in order to connect over the river. The first and only other known bridge to be built at Massena Center was built in 1832, but that bridge was never long for this world. During the spring of 1833, the Grasse River dammed itself due to an ice dam, flooded and lifted the bridge off its foundation, destroying the bridge in the process. The floods were frequent in the river during the spring, often backing up the river from Hogansburg and past Massena Center, but not to nearby Massena. After the first bridge disappeared, local residents had to resort to traveling seven miles west to Massena to cross the next closest bridge, and that was no easy task for a horse and buggy. However, it was many decades befo...

The Dead Man's Curve of Interstate 90 and Innerbelt Freeway in Cleveland

"Dead Man's Curve" refers to the transition ramp Interstate 90 takes between Cleveland Memorial Shoreway onto the Innerbelt Freeway in downtown Cleveland, Ohio. Said curve includes a sharp transition between the two freeways which is known for a high rate of accidents. Currently the curve (not officially named) has a 35 MPH advisory speed and numerous safety features intended to mitigate crashes. When the Interstate System was first conceived during 1956, Interstate 90 was intended to use the entirety Cleveland Memorial Shoreway and connect to the Northwest Freeway through Lakewood. The Innerbelt Freeway was initially planned as the northernmost segment of Interstate 71. The extension of Cleveland Memorial Shoreway west of Edgewater Park was never constructed which led to Interstate 90 being routed through the Innerbelt Freeway.
