Old Creek Road

After completing Signed County Route G14 I headed on California State Route 46 west of Paso Robles to Old Creek Road.

Old Creek Road is a short connecting route between CA 46 and CA 1. Old Creek Road is a somewhat infamous road in San Luis Obispo County that draws a lot of interest from motorcycle groups. Interestingly Old Creek Road not only has a junction with CA 46 but also Santa Rosa Creek Road which was a former alignment of CA 41 before the 1964 Highway Renumbering in addition to post 1964 CA 46.

Old Creek Road starts with a simple advisory sign that the next 5 miles are curvy which is an understatement.

From CA 46 Old Creek Road descends on a tall downhill grade from about 1,300 feet above sea level to 220 feet at the Whale Rock Reservoir. Old Creek Road is extremely narrow through this section and the road bed has deep groves to deter lane crossing.

The Whale Rock Reservoir was completed in 1961 and impound Old Creek. Its kind of strange to see a man-made lake floating above the Pacific Ocean which clearly can be seen not far to the west.

At the Whale Rock Reservoir the grade of Old Creek Road becomes far more shallow and it enters Cayucos where it terminates at CA 1.

Interestingly Old Creek Road has been around for quite a long time and probably was an even more useful road before CA 46 was realigned onto it's modern routing off Santa Rosa Creek Road. The alignment of Old Creek Road can clearly be seen on the 1935 California Division of Highways map of San Luis Obispo County. Interestingly it appears Old Creek Road used to run through what is now Whale Rock Reservoir onto 13th Street in Cayucos. I find it odd that Old Creek Road never received a Signed County Route designation given that it would have made for a decent addition to the system and is old enough to be exempt from modern width requirements.

Grand Loop Road of Yellowstone National Park

Grand Loop Road is a 140 mile loop highway which traverses the interior of Yellowstone National Park. Grand Loop Road connects all of the major attractions and geological features of Yellowstone National Park along with the entrance roads. Grand Loop Road is a seasonal highway and despite some conjecture never has been part of the US Route System. Part 1; the history of Grand Loop Road The majority of history pertaining to Grand Loop Road was taken from the below National Park Service article: Historic Roads - Yellowstone National Park (U.S. National Park Service) (nps.gov) Yellowstone was declared the first National Park of the United States on March 1st, 1872. The first real highway to access Yellowstone National Park came in 1873 when a tolled facility was constructed from Bozeman, Montana via Yankee Jim Canyon to Mammoth Hot Springs. Numerous attempts were made to fund construction of roadway infrastructure during the early years of Yellows...

The last 1956-63 era California Sign State Route Spade?

Along southbound California State Route 170 (the Hollywood Freeway Extension) approaching the Hollywood Freeway/Ventura Freeway interchange a white California State Route 134 Sign State Route Spade can be observed on guide sign. These white spades were specifically used during the 1956-63 era and have become increasingly rare. This blog is intended to serve as a brief history of the Sign State Route Spade. We also ask you as the reader, is this last 1956-63 era Sign State Route Spade or do you know of others? Part 1; the history of the California Sign State Route Spade Prior to the Sign State Route System, the US Route System and the Auto Trails were the only highways in California signed with reassurance markers. The creation of the US Route System by the American Association of State Highway Officials during November 1926 brought a system of standardized reassurance shields to major highways in California. Early efforts to create a Sign State Route ...

California State Route 70; the Feather River Highway

From 2017 through to early 2019 I drove the majority of the California State Route 70; the Feather River Highway from CA 89 southwest to CA 99. CA 70 is an approximately 178.5 mile state highway which starts at US 395 near the Nevada State Line and travels west through the Feather River Canyon to CA 99. CA 70 is often referred to as the Feather River Highway" given it's close association with the river. Historically CA 70 was previously signed as US 40A and CA 24. The Legislative Routes prior to the 1964 California Highway Renumbering that made up the current route of CA 70 are as follows: - Legislative Route Number 21 from US 395 westward to Oroville. - LRN 87 from Oroville south to Marysville. - LRN 232 from Marysville to the current junction with CA 99. CA 70 was even dual signed with CA 99 into Sacramento on what was LRN 232 for a time. The change from US 40A/LRN 21/LRN 87/LRN 232 can be seen by comparing the 1963 State Highway Ma...
