Monterey County Route G18


Monterey County Route G18 is a 16.40-mile highway aligned over Jolon Road from US Route 101 near Bradley to Monterey County Route G14 in Lockwood.  The corridor of Jolon Road is tied heavily to the history of the Spanish El Camino Real and Mission San Antonio de Pauda.  Jolon Road was improved during World War II after the creation of Fort Hunter Liggett.  Jolon Road was assigned as part of Monterey County Route G18 and Monterey County Route G14 during 1971.  The segment of Jolon Road between Bradley-Lockwood now part of Monterey County Route G18 from the March 1943 California Highways & Public Works is featured as the blog cover.  




Part 1; the history of Monterey County Route G18 and Jolon Road

The corridor of Monterey County Route G18 and Jolon Road is tied to that of the Spanish iteration of El Camino Real and Mission San Antonio de Pauda.  The Santa Lucia Mountains and general course of the San Antonio River were explored by the Spanish during 1769 Portola Expedition of Las Californias.  Mission San Antonio de Pauda was founded during 1771 near the San Antonio River.  The San Antonio River proved to be a reliable source of water for irrigation purposes between Mission San Miguel Arcangel and Mission Nuestra Senora de la Soledad.  Thusly general path of the Spanish iteration of El Camino Real followed the general corridor of modern Jolon Road from Mission San Miguel Arcangel through the Santa Lucia Mountains towards Mission Nuestra Senora de la Soledad.  

During the period of early American statehood in California the major stage roads used the highways inherited from Mexican Alta California.  The road north of San Miguel still followed the general corridor of Jolon Road towards Mission Soledad via Mission San Antonio.  The main stage road from San Miguel is seen following the San Antonio River towards Mission San Antonio and northward towards Mission Soledad on the 1857 Britton & Rey's Map of California.  


During the 1870s and 1880s the Southern Pacific Railroad constructed a line through Salinas Valley towards San Miguel.  The Southern Pacific Railroad would develop frontage roads which would replace the corridor of Jolon Road as the primary through highway between San Miguel and Mission Soledad.  These frontages during the 20th Century would form the basis of Legislative Route Number 2 as part of 1909 First State Highway Bond Act and US Route 101 when the US Route System was created during November 1926.  

Jolon Road can be seen in detail as a major local highway on the 1935 Division of Highways Map of Monterey County.  Jolon Road can be seen originating at US Route 101 near Bradly and looping back to it near King City.  Jolon Road east of Lockwood is shown to be following what is now Bradley-Lockwood Road  



Jolon Road became prominent during World War II due to the formation of Fort Hunter Liggett during 1940 near Jolon. Forty miles of improvements of Jolon Road began as a Work Projects Administration (WPA) project during early 1941 and would conclude during late year 1942. The segment of Jolon Road between Bradly to Lockwood was straightened as part of the corridor improvements. The improvements to Jolon Road were featured in the 1943 California Highways & Public Works.








Jolon Road facing south from US Route 101 near King City can be seen in a photo form the July/August 1945 California Highways & Public Works.  


During 1971 Jolon Road was assigned as Monterey County Route G14 and Monterey County Route G18.  Monterey County Route G18 was assigned to the 16.40 miles of Jolon Road east of Lockwood.  Monterey County Route G14 was assigned to the 23.82 miles northwest of Lockwood.  At some point between the mid-1970s and early 1980s the Jolon Grade on Monterey County Route G14 north of Jolon was straightened.  



Part 2; a drive on Monterey County Route G18

Monterey County Route G18 and Jolon Road begin from US Route 101 Exit 252 near Bradley.  Monterey County Route G18 is mistakenly signed as "Monterey County Route 18" by Caltrans.  Traffic wishing to access Mission San Antonio is directed to utilize Monterey County Route G18.




Monterey County Route G18/Jolon Road crosses under US Route 101 and intersects Monterey County Route G19 at Nacimiento Lake Drive.  





Monterey County Route G18/Jolon Road is signed as 18 miles from Lockwood.


Monterey County Route G18/Jolon Road passes through Hames Valley and enters the Santa Lucia Mountains.  







Monterey County Route G18/Jolon Road crosses through a small portion of the Santa Lucia Mountains and enters the San Antonio River Valley.  Monterey County Route G18/Jolon Road intersects the earlier alignment mentioned in Part 1which is now signed Bradley-Lockwood Road.  











Monterey County Route G18/Jolon Road enters the community of Lockwood.  Monterey County Route G18 ends at Interlake Road and Jolon Road transitions onto Monterey County Route G14.  Lockwood is named in honor of Belva Lockwood who ran for President on the Equal Rights Party ticket in 1884 and 1888.  Post Office Service in Lockwood was established in 1888.

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
