Old 1916 Elkhorn Avenue Concrete Pony Truss Bridge

The other day I was browsing bridgehunter.com when I noticed that there an old Concrete Pony Truss bridge spanning the Fresno Slough in rural Fresno County near Burrell on Elkhorn Avenue. Today I went out to the old span to grab some photos.

The Old Elkhorn Avenue Bridge apparently dates back from 1916 according to bridgehunter.com.

Old Elkhorn Avenue Bridge

I don't have an exact date for the replacement Elkhorn Avenue span over Fresno Slough but the old grade still has paint which makes it apparent the replacement probably was built in the last two decades.

As stated above the Old Elkhorn Avenue Bridge spans Fresno Slough. Fresno Slough is a tributary connecting the Kings River to northwest to the San Joaquin River. Before Tulare Lake dried up it would occasionally crest at about 210 feet above sea level which caused a back flow into the Kings River. The back flow of Tulare Lake would in turn flow through Fresno Slough towards the San Joaquin River. Today Fresno Slough rarely has water in it aside from irrigation diversion.

The Old Elkhorn Avenue Bridge can be walked across but there isn't a plaque or indicator to tell travelers any details about the bridge.

Interestingly on the 1935 California Division of Highways Map of Fresno County the modern Elkhorn Avenue is shown as Dodge Avenue. A different Elkhorn Avenue is shown two miles to the south along modern Cerini Avenue.

The reason the Old Elkhorn Bridge was likely built was the proximity to the Riverdale Branch Railroad and it's siding in Burrel. The Riverdale Branch Railroad was built in 1910 and has largely been razed. There is still a modern line terminating in Burrel to this day.

California State Route 232

This past month I drove the entirety of California State Route 232 in Ventura County. CA 232 is an approximately 4 miles State Highway aligned on Vineland Avenye which begins near Saticoy at CA 118 and traverses southwest to US Route 101 in Oxnard. The alignment of CA 232 was first adopted into the State Highway System in 1933 as Legislative Route Number 154 according to CAhighways.org. CAhighways.org on LRN 154 As originally defined LRN 154 was aligned from LRN 9 (future CA 118) southwest to LRN 2/US 101 in El Rio. This configuration of LRN 154 between CA 118/LRN 9 and US 101/LRN 2 can be seen on the 1935 California Division of Highways Map of Ventura County. 1935 Ventura County Highway Map According to CAhighways.org the route of LRN 154 was extended west from US 101/LRN 2 to US 101A/LRN 60 in 1951. Unfortunately State Highway Maps do not show this extension due to it being extremely small. During the 1964 State Highway Renumbering LRN 154 was assigned CA 232. Of n

Interstate 40 and the H-Bomb

Interstate 40 within California is entirely contained to San Bernandio County over a course of 155 miles from Interstate 15 in Barstow east to the Arizona State Line at the Colorado River. Interstate 40 is aligned entirely in the Mojave Desert over the same general corridor established by US Route 66 and the National Old Trails Road. Interstate 40 is known as the Needles Freeway and has an interesting backstory which included the prospect of the Bristol Mountains being excavated by way of nuclear blasts as part of Operation Carryall. Part 1; the history of Interstate 40 in California The focus on this blog will be primarily centered around the construction of Interstate 40 ("I-40") within California. That being said the corridor of automotive travel east of Barstow to the Arizona State Line was largely pioneered by the National Old Trails Road ("NOTR") In April of 1912 the NOTR was organized with the goal of signing a trans-continental highway between Baltim

Interstate 15 Exit 239 to Zzyzx Road; intersecting the Mojave Road and Tonopah & Tidewater Railroad

Interstate 15 Exit 239 in the Mojave Desert of northern San Bernardino County, California accesses the well known oddity of Zzyzx Road. Zzyzx Road connects 4.5 miles from Interstate 15 to a small community of the same name which is located on the shore of the dry Soda Lake. "Zzyzx" was coined in 1944 by Curtis Howe Springer as what he promoted as to be last word in the English Language. On the surface Zzyzx appears to be something of a modern invention but the area has significant overall historical importance as part of a transportation corridor through the Mojave Desert. Zzyzx lies at a point which was the intersection of the Mojave Road of the 19th Century the Tonopah & Tidewater Railroad of the early 20th Century. The backstory of Soda Springs, the Mojave Road, Tonopah & Tidewater Railroad and Zzyzx The present site of Zzyzx is located upon a natural spring along the western shore of Soda Dry Lake. This spring has historically been known as "Soda S
