Old US Route 99 through Herndon, CA



While researching the earliest routings of US Route 99 in California recently I found a very old alignment through Herndon of Fresno County, California north over the San Joaquin River.

This blog is part of the larger Gribblenation US Route 99 Page.  For more information pertaining to the other various segments of US Route 99 and it's three-digit child routes check out the link the below.



Former US Route 99 through Herndon

Herndon dates back to the 1860s when it was founded as a ferry landing on the San Joaquin River.  Said ferry landing was used to supply the first Fresno County seat of Millerton which was located upstream near the present location of Friant Dam.  In 1872 the Central Pacific Railroad organized a community known as "Sycamore" and built a roadway bridge east of the railroad tracks along what is now Weber Avenue.  The modern name of Herndon apparently dates back to a Post Office name change in 1887.  The original 1872 Herndon Bridge would be replaced by truss span in 1903 at the same location.


The earliest alignments of Legislative Route 4 were incorporated into the State Highway network by 1910 when the 1909 First State Highway Bond Act was approved by voters.  By proxy the original "Herndon Bridge" along Weber Avenue was incorporated as the highway crossing for LRN 4 over the San Joaquin River.  Said route of LRN 4 over the Herndon Bridge can be seen on the 1914 Fresno County Map below.

In late 1926 the US Route system was finalized and US 99 was selected to run over the alignment of LRN 4 in San Joaquin Valley.  As a result the Herndon Bridge was incorporated into the earliest alignment of US 99.  This alignment didn't last long as a replacement span was built west of the Southern Pacific Railroad tracks and Herndon at the San Joaquin River which was completed by June 1929.  The 1929 bridge is still in use as part of modern CA 99 but has been heavily modified to serve modern traffic.  Various photos showing the older truss structure of the 1929 bridge can be found on Bridgehunter.com.

Update 4/17/19:  I was provided a link by AAroads forum user Kniwt regarding the Herndon Bridge crossings from a 1927 California Highway and Public Works publication.  Said volume details the history of the 1903 Herndon Bridge on page 555 and an overview of the 1928 replacement span project on page 552.

The 1903 Herndon Bridge still appears on the 1935 California Division of Highways Map of Fresno County.  I'm uncertain when the Herndon Bridge was demolished.

This custom map below shows the differences between the original alignment of US 99 through Herndon compared to the 1929 (shown in error as 1928) alignment.


From Belmont Avenue near downtown Fresno the route of US 99 would have originally followed what is now Golden State Boulevard to Herndon Avenue.  US 99 would have crossed the Southern Pacific Railroad tracks on Herndon Avenue before swinging north on Weber Avenue into Herndon.





Weber Avenue through Herndon north to Cattern Avenue doesn't resemble an early US Route in the slightest.



North of Cattern Avenue traffic on Weber Avenue is advised there is no outlet to the north.  After a quick turn Weber Avenue changes drastically dropping down to a single lane of concrete top layered in dirt.




Weber Avenue continues north to the location of the Herndon Bridge at the San Joaquin River.  The San Joaquin River Viaduct which is part of the current High Speed Rail construction can be seen in the background.










The San Joaquin River can no longer be accessed via Weber Avenue but the location of the Herndon Bridge can be seen at the end of the concrete in the photo below.


Doubling back to Golden State Boulevard north of Herndon Avenue the 1929 alignment of US 99 over the San Joaquin River Bridge is much straighter and far more direct.  To the east of the 1929 alignment of US 99 the Union Pacific tracks (formerly Central Pacific and Southern Pacific) can be seen along with the not fully completed High Speed Rail San Joaquin River Viaduct.


The 1928 alignment of US 99 merges onto the CA 99 freeway and crosses the San Joaquin River as the northbound lanes.  It is virtually impossible to tell from the CA 99 freeway that the northbound lanes are traveling on a bridge from 1929.  Mid-way through the 1929 San Joaquin River Bridge US 99 would have entered Madera County.









From the Exit 144 sign for Avenue 7 the older alignment of US 99 can be seen near the UP tracks.  The original alignment of US 99 would have come in from the left and crossed the rails.


From the Avenue 7 overpass a remaining portion of Road 33 can be seen looking southward towards the San Joaquin River Viaduct.  The derelict curve is where the original alignment of US 99 met the 1929 alignment.



From the Avenue 7 overpass the original alignment of US 99 west of the Union Pacific tracks is partially intact as a rail frontage road.

California State Route 190; a Trans-Sierra Highway that could have been

This past week I decided to take a small scale road trip on California State Route 190 from CA 99 east to the unbuilt section over the Sierra Nevada Range.  While I was in for what turned out to be a fun drive following the course of the Tule River watershed what I found researching the back story of CA 190 was one of the most complex and unusual stories of any California State Highway.  Given that I had a ton of older photos of the eastern segment of CA 190 in the Mojave Desert of Inyo County I thought it was time to put something together for the entire route. The simplified story of CA 190 is that it is a 231 mile state highway that has a 43 mile unbuilt gap in the Sierra Nevada Range.  CA 190 is an east/west State Highway running from CA 99 in Tulare County at Tipton east to CA 127 located in Death Valley Junction near the Nevada State Line in rural Inyo County.  The routing CA 190 was adopted into the State Highway system as Legislative Route 127 which was adopted in 1933 acc

I-73/I-74 and NC Future Interstates, Year in Review 2022

Another year over, already? 2022 turned out to be quite the year if you are a fan of new interstate routes, and it wasn't bad for some long standing favorites. As per the tradition, I will review what happened with I-73 and I-74, and then the other new and future interstate routes in North Carolina... Work continued on the one segment of I-73 under construction, the I-73/I-74 Rockingham Bypass. As of the beginning of December, work was getting close to being 2/3 complete at 60.1%. Progress could be seen from US 74 on constructing of the future interchange at the Bypass's southern end. Here's a look from US 74 East in September from Google Maps Street View: Here's a photo from US 74 West taken last week by David Gallo: Work is now scheduled to be completed in October 2025, though the road itself could open earlier that year.  Progress on I-74 earned more publicity in 2022 with the opening of 7.5 more miles of the Winston-Salem Northern Beltway from US 311 (Exit 49) to NC

Interstate 605

Interstate 605 is a 27.4-mile freeway located in the Los Angeles Metropolitain Area.  Interstate 605 begins at Interstate 210 near Duarte and terminates at the Interstate 405/California State Route 22 junction to the south near the boundary to the city of Long Beach.  Interstate 605 is known as the San Gabriel River Freeway and has three unconstructed miles which would extend it south to California State Route 1 near Seal Beach.  Much of the corridor of Interstate 605 was built up from what was the original California State Route 35.  The blog cover photo is taken from the July/August 1964 California Highways & Public Works which featured the initial segment of Interstate 605 to open between Whittier Boulevard and Peck Road  Part 1; the history of the San Gabriel River Freeway and Interstate 605 The origin of what is now Interstate 605 begins during 1933 with the addition of Legislative Route Number 170 (LRN 170) to the State Highway System.  The original definition of LRN 170 was
