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.

The Central Freeway of San Francisco (US Route 101)

The Central Freeway is a 1.2-mile elevated limited access corridor in the city of San Francisco.  As presently configured the Central Freeway connects from the end of the Bayshore Freeway to Market Street.  The Central Freeway carries the mainline of northbound US Route 101 from the Bayshore Freeway to Mission Street. The Central Freeway has origins with the establishment of Legislative Route Number 223 and is heavily tied to the history of the once proposed Panhandle Freeway.  The Central Freeway between the Bayshore Freeway and Mission Street was completed during 1955.  The corridor was extended to a one-way couplet located at Turk Street and Golden Gate Avenue in 1959 which served to connect US Route 101 to Van Ness Avenue.  The Central Freeway was damaged by the 1989 Loma Prieta Earthquake and has since been truncated to Market Street.   The Central Freeway as pictured on the blog cover was featured in the May/June 1959 California Highways & Public Works.  The scan below is fro

The Bayshore Freeway (US Route 101)

The Bayshore Freeway is a 56.4-mile component of US Route 101 located in the San Francisco Bay Area.  The Bayshore Freeway connects the southern extent of San Jose to the Central Freeway in the city of San Francisco.  The corridor was originally developed as the Bayshore Highway between 1923 and 1937.  The Bayshore Highway would serve briefly as mainline US Route 101 before being reassigned as US Route 101 Bypass in 1938.  Conceptually the designs for the Bayshore Freeway originated in 1940 but construction would be delayed until 1947.  The Bayshore Freeway was completed by 1962 and became mainline US Route 101 during June 1963.   Part 1; the history of the Bayshore Freeway Prior the creation of the Bayshore Highway corridor the most commonly used highway between San Jose and San Francisco was El Camino Real (alternatively known as Peninsula Highway).  The  American El Camino Real  began as an early example of a signed as an Auto Trail starting in 1906.  The era of State Highway Mainte

Former US Route 101 and California State Route 41 through Paso Robles

Paso Robles is a city located on the Salinas River of San Luis Obispo County, California.  As originally configured the surface alignments of US Route 101 and California State Route 41 converged in downtown Paso Robles.  US Route 101 originally was aligned through Paso Robles via Spring Street.  California State Route 41 entered the City of Paso Robles via Union Road and 13th Street where it intersected US Route 101 at Spring Street.  US Route 101 and California State Route 41 departed Paso Robles southbound via a multiplex which split near Templeton.   Pictured above is the cover of the September/October 1957 California Highways & Public Works which features construction of the Paso Robles Bypass.  Pictured below is the 1935 Division of Highways Map of San Luis Obispo County which depicts US Route 101 and California State Route 41 intersecting in downtown Paso Robles.   Part 1; the history of US Route 101 and California State Route 41 in Paso Robles Paso Robles ("Pass of the
