Unconstructed California State Route 234

California State Route 234 is a three-mile unconstructed State Highway which was planned near the southern city border of Stockton near French Camp.  The corridor which was adopted into the State Highway System by way of 1959 Legislative Chapter 1062.  The traversable routing of California State Route 234 is noted by Caltrans as French Camp Road despite it not matching the planned corridor routing displayed on State Highway Maps.  During 1983 San Joaquin County adopted a resolution to adopt French Camp Road formally California State Route 234.  The state never acted on the resolution and San Joaquin eventually lost interest.  Modern Arch Airport Road was completed in 2010s along the planned corridor of California State Route 234.  Arch Airport Road facilitates traffic to newer industrial construction at Airpark 599 near Stockton Metropolitain Airport.  

Planned California State Route 234 can be seen straddling the southern city border of Stockton on the blog cover as displayed on 1964 Division of Highways Map.  

The history of California State Route 234

What was to become planned California State Route 234 was added to the State Highway System during 1959 as Legislative Route Number 261 (LRN 261).  LRN 261 was adopted into the Freeways & Expressways System which was also created during 1959.  LRN 261 was defined by Legislative Chapter 1062 with the following description:

"LRN 238 (Interstate 5) near French Camp to LRN 4 (US Route 99"

LRN 261 appears for the first time on the 1960 Division of Highways Map as a planned State Highway.  The planned but unadopted routing of LRN 261 is shown to be aligned north of French Camp near the southern boundary of the city of Stockton.  The planned alignment of LRN 261 included a crossing of French Camp Slough approaching Interstate 5/LRN 238. 

The Legislative Route Numbers were dropped as part of the 1964 State Highway Renumbering.  LRN 261 was subsequently renumbered as "California State Route 234."  California State Route 234 retained the definition of LRN 261 and appears on the first time on the 1964 Division of Highways.  

Unconstructed California State Route 234 roughly aligned with then existing Sperry Road between McKinnley Avenue and Airport Way (County Route J3).  The corridor appears to have been intended to service Sharpe Army Depot Field Annex which was located at Stockton Municipal Airport.  Sperry Road can be seen as originally configured on the 1968 United States Geological Survey Map of Stockton.  The regular Army would withdraw from Stockton Municipal Airport during 1973 and the holdings of Sharpe Army Depot Field Annex were relinquished to San Joaquin County. 

California State Route 234 never had a formal alignment adoption.  In 1983 San Joaquin County passed resolution 8-83-1461 for procedures to be followed to add French Camp Road as California State Route 234 and Eight Mile Road as California State Route 235.  French Camp Road (County Route J9 and former US Route 99) is listed as the traversable routing of California State Route 234, but no State Highway map has ever shown the planned corridor following it.   During 1993 San Joaquin County adopted Eight Mile Road as arterial roadway and dropped interest in California State Route 235.  San Joaquin County never opined on continued interest with California State Route 234.

Sperry Road by the 1980s was extended east from Airport Way to California State Route 99 (former US Route 99) by San Joaquin County via the planned corridor of California State Route 234.  This extension appears on the 1989 United States Geological Map of Stockton.  

The corridor of Sperry Road was extended west to Interstate 5 and renamed as "Arch Airport Road" during the latter half of the 2010s.  Arch Airport Road is aligned directly over the planned corridor of California State Route 234.  The intent of Arch Airport Road is to increase access to Stockton Metropolitain Airport and the Airpark 599 (which broke ground in 2021).  

Arch Airport Road as it is configured now appears on the 2015 United States Geological Map of Stockton.

Paper Highways: The Unbuilt New Orleans Bypass (Proposed I-410)

  There are many examples around the United States of proposed freeway corridors in urban areas that never saw the light of day for one reason or another. They all fall somewhere in between the little-known and the infamous and from the mundane to the spectacular. One of the more obscure and interesting examples of such a project is the short-lived idea to construct a southern beltway for the New Orleans metropolitan area in the 1960s and 70s. Greater New Orleans and its surrounding area grew rapidly in the years after World War II, as suburban sprawl encroached on the historically rural downriver parishes around the city. In response to the development of the region’s Westbank and the emergence of communities in St. Charles and St. John the Baptist Parishes as viable suburban communities during this period, regional planners began to consider concepts for new infrastructure projects to serve this growing population.  The idea for a circular freeway around the southern perimeter of t

Hernando de Soto Bridge (Memphis, TN)

The newest of the bridges that span the lower Mississippi River at Memphis, the Hernando de Soto Bridge was completed in 1973 and carries Interstate 40 between downtown Memphis and West Memphis, AR. The bridge’s signature M-shaped superstructure makes it an instantly recognizable landmark in the city and one of the most visually unique bridges on the Mississippi River. As early as 1953, Memphis city planners recommended the construction of a second highway bridge across the Mississippi River to connect the city with West Memphis, AR. The Memphis & Arkansas Bridge had been completed only four years earlier a couple miles downriver from downtown, however it was expected that long-term growth in the metro area would warrant the construction of an additional bridge, the fourth crossing of the Mississippi River to be built at Memphis, in the not-too-distant future. Unlike the previous three Mississippi River bridges to be built the city, the location chosen for this bridge was about two

Memphis & Arkansas Bridge (Memphis, TN)

  Like the expansion of the railroads the previous century, the modernization of the country’s highway infrastructure in the early and mid 20th Century required the construction of new landmark bridges along the lower Mississippi River (and nation-wide for that matter) that would facilitate the expected growth in overall traffic demand in ensuing decades. While this new movement had been anticipated to some extent in the Memphis area with the design of the Harahan Bridge, neither it nor its neighbor the older Frisco Bridge were capable of accommodating the sharp rise in the popularity and demand of the automobile as a mode of cross-river transportation during the Great Depression. As was the case 30 years prior, the solution in the 1940s was to construct a new bridge in the same general location as its predecessors, only this time the bridge would be the first built exclusively for vehicle traffic. This bridge, the Memphis & Arkansas Bridge, was completed in 1949 and was the third
