2016 Fall Mountain Trip Part 9; Interstate 15 through the Virgin River Gorge

After returning from Old St. Thomas Road I continued north out of the Lake Mead National Recreation Area onto Nevada State Route 169.  I next took NV 169 northward on Moopa Valley Boulevard to Interstate 15.  My next destination was in Snow Canyon which meant the most direct route through the Virgin River Gorge on I-15.

2016 Fall Mountain Trip; Former Nevada State Route 12 on Old St. Thomas Road

NV 169 ends at I-15 exit 93 where I turned north towards Arizona.


On a recent winter trip this year I covered the history of I-15 in Arizona/Virgin River Gorge and how it differs from US Route 91.  The previous blog on the Virgin River Gorge section of I-15 can be found here:

2018 Mojave Desert Road Trip Part 5; Interstate 15 in Arizona

On the previous I-15/Virgin River Gorge blog I noted the following about history of the Interstate in Arizona:

"Unlike US Route 91 which dipped into Utah upstream on the Virgin River the routing of I-15 was constructed through the Virgin River Gorge to save approximately 12 miles.  Despite the canyon depths the Virgin River Gorge was found to have more shallow grades than the alignment of US 91.  I-15 was under construction in Arizona from the early 1960s until it was completed in 1973.  The northwest corner of the Arizona state highway maps in 1961 and 1971 show the progression from US 91 to an almost complete I-15.

The 2016 Arizona Department of Transportation web map book shows how different the route of I-15 is compared to US 91.

Ironically my previous blog on the Virgin River Gorge was from I-15 southbound.  In 2016 I was headed the opposite way on northbound I-15 which is every bit as scenic.
















Upon entering Washington County, Utah I pulled off of I-15 onto Utah State Route 18 on Bluff Street in St. George.


Given my next destination was at Snow Canyon State Park I followed UT 18 northward to UT 8 on Sunset Boulevard.

Yes, the color of your nearby fire hydrant matters...

...and here's why. You will find White, Red, Yellow and Violet colored fire hydrants pretty much everywhere.  But there's a reason for this - and it's because of the National Fire Protection Association (NFPA).  This association has issued guidelines for color coding standards for fire hydrants.  These color codes from the body of the hydrant, top of the hydrant, and in some municipalities the outlet caps are designed to allow fire fighters to know what type of system, water flow rate (Gallons Per Minute or GPM), and level of water pressure.  This guideline is known as NFPA 291 and is intended to be used universally throughout the United States. The NFPA guidelines are specific to the body and the top cap of the hydrant.  If a hydrant is WHITE or YELLOW - it means that it is connected to a public/municipal water system.  If a hydrant is RED - the hydrant is connected to a private system, typically a well.  These are most common in rural or unincorporated areas

Phase 1 of the California State Route 132 West Expressway (in the making since 1947)

On September 15, 2022, the Phase 1 of the California State Route 132 West Expressway opened in the city of Modesto from California State Route 99 west to North Dakota Avenue.  Phase 1 of the California State Route 132 West Expressway was built upon a corridor which was tentatively to designated to become the branching point for Interstate 5W in the 1947 concept of the Interstate Highway System.  The present California State Route 132 West Expressway corridor was adopted by the California Highway Commission on June 20, 1956.  Despite almost being rescinded during the 1970s the concept of the California State Route 132 West Expressway corridor lingered on for over half a century and became likely the oldest undeveloped right-of-way owned by California Transportation Commission.  Pictured above is the planned California State Route 132 freeway west of US Route 99 in Modesto as featured in the May/June 1962 California Highways & Public Works.   The history of the California State Route

Aptos Creek Road to the Loma Prieta ghost town site

Aptos Creek Road is a roadway in Santa Cruz County, California which connects the community of Aptos north to The Forest of Nisene Marks State Parks.  Aptos Creek Road north of Aptos is largely unpaved and is where the town site of Loma Prieta can be located.  Loma Prieta was a sawmill community which operated from 1883-1923 and reached a peak population of approximately three hundred.  Loma Prieta included a railroad which is now occupied by Aptos Creek Road along with a spur to Bridge Creek which now the Loma Prieta Grade Trail.  The site of the Loma Prieta Mill and company town burned in 1942.   Part 1; the history of Aptos Creek Road and the Loma Prieta town site Modern Aptos traces its origin to Mexican Rancho Aptos.  Rancho Aptos was granted by the Mexican Government in 1833 Rafael Castro.  Rancho Aptos took its name from Aptos Creek which coursed through from the Santa Cruz Mountains to Monterey Bay.  Castro initially used Rancho Aptos to raise cattle for their hides.  Following
