Acton Grade Bridge (Madera County Road 810)


The Acton Grade Bridge is a deck plate span crossing the East Fork Chowchilla River on Madera County Road 810 (formerly Acton Grade Road).  The bridge likely was installed during the early 1970s to replace the earthen ford which once connected the California Gold Rush communities of Bailey Flats and Grub Gulch.  The name of the structure is an homage to late nineteenth century property owner Mary E. Acton who granted an easement to construct what is now Road 810.  Road 810 itself is an approximately four-mile dirt road which connects Road 800 (formerly Bailey Flats Road) southeast to Road 600 (formerly Grub Gulch Road).  




Part 1; the history of the Acton Grade

The Acton Grade (now Madera County Road 810) connected the Gold Rush era communities of Grub Gulch and Bailey Flats via the East Fork Chowchilla River.  

Bailey Flats was named after Gillium Baley a settler from Gallatin, Illinois. Baley emigrated to California with his family during 1858-1859 and initially settle in Visalia. Baley would move to the original Fresno County seat of Millerton during 1860. While in Millerton, Baley would stake mining claims along the San Joaquin River, Fresno River and Chowchilla River. Baley's mining claims along the Chowchilla River were located near the confluence of the three forks of the watershed at what came to be known as "Bailey Flats." Baley would establish his homestead along the Chowchilla River during 1862-1863.

Baley would be elected as Fresno County judge during 1867 and would return to Millerton. Baley would remain the Fresno County Judge during the change of county seat to Fresno in 1874 and would retire in 1878. Following his retirement Baley would return to Bailey Flats.

Grub Gulch developed after the opening of the Gambetta Mine in 1880.  Grub Gulch obtained Post Office service during 1883 and reportedly may have had a population as high as 5,000 residents.  Grub Gulch can be seen along the Yosemite Stage Road in a public domain photo from 1885.  


Bailey Flats and Grub Gulch are located in Townships 6-7 South, Range 20 East which can be seen on the 1891 Thompson Atlas of Fresno County. Grub Gluch is shown at the time not to have a direct road connection with Bailey Flats. The map displays property along the East Fork Chowchilla River belonging to Mary E Acton can be seen. Madera County would split from what was northern Fresno County on May 16, 1893.



Following the death of Gillium Bailey during November 1895 a small community would begin to develop at Bailey Flats. The Bailey Flats School opened in 1900 and the community once had a general store (the below image is image hosted at cagenweb.org).


Bailey Flats can be seen connected to Grub Gulch via the then new Acton Grade Road on the 1912 United States Geological Survey Map of Mariposa. The road through Bailey Flats is shown to terminate to the west at Coleman Flat. It is likely that the Acton Grade Road initially crossed the East Fork Chowchilla River via an earthen ford.


Bailey Flats obtained Post Office service in 1913 and was renamed as "Mist." Bailey Flats can be seen on the 1914 Smith Map of Madera County in Township 6 South, Range 20 East.


The Mist Post Office would be shuttered in 1935 and service would move to Raymond. Mist can be connected to Grub Gluch via Acton Grade Road along with the then newly completed Bailey Flats Road to Raymond on the 1935 Division of Highways Map of Madera County.


The Bailey Flats School would close in 1947. Today the only traces of Bailey Flats remaining are a handful of abandoned buildings. Bailey Flats is no longer displayed at the western end of Acton Grade Road on the 1947 United States Geological Survey Map of Mariposa.


Madera County would eventually drop their county road names in favor of a numbering system.  Within the Sierra Nevada range the road system began in the 100s and ascended westward to the 800 range.  What was Bailey Flats Road was renumbered as Road 800 whereas Acton Grade Road became Road 810.  

It isn't clear when the Acton Grade Bridge was constructed.  The structure first appears on aerial imagery of the Bailey Flats area beginning in 1983.  The span may have been installed during 1972 according to the Madera County History Facebook page. 



Part 2; a visit to the Acton Grade Bridge

Northbound Madera County Road 800 intersects eastbound Road 810 via a right-hand turn at the site of the community of Bailey Flats.  

 

Road 810 crosses the East Fork Chowchilla River via the deck plate bridge Acton Grade Bridge.  An earthen ford can be seen just south of the span.

Did Caltrans just kill the G26 cutout US Route shields?

The US Route System was formally created by the American Association of State Highway Officials during November 1926.  Through the history of the system the only state to which has elected to maintain cutout US Route shields has been California.  The G26 series cutout US Route shields have become a favorite in the road enthusiast hobby and are generally considered to be much more visually pleasing than the standard Federal Highway Administration variant.  However, the G26 shield series appears to have been killed off on January 18, 2026, when Caltrans updated their Manual of Uniform Traffic Control Devices.  This blog will examine the history of the US Route shield specifications in California and what is happening with the 2026 changes.  The blog cover photo is facing towards the terminus of California State Route 136 and at a G26-2 specification US Route 395 shield.  In the background Mount Whitney can be seen in the Sierra Nevada range.   ...

May 2023 Ontario Trip (Part 3 of 3)

  Over the years, I have made plenty of trips to Ontario, crisscrossing the southern, central and eastern parts of the province. Living in Upstate New York, it's pretty easy to visit our neighbor to the north, or is that our neighbor to the west? Ottawa is one of my favorite cities to visit anywhere in the world, plus I've discovered the charm of Kingston, the waterfalls of Hamilton (which is on the same Niagara Escarpment that brings us Niagara Falls), the sheer beauty of the Bruce Peninsula, and more. But I hadn't explored much of Cottage Country. So I decided to change that, and what better time to go than over Memorial Day weekend, when the daylight is long and I have an extra day to explore. On the third and final day of my trip, I started in Huntsville and made my way through Muskoka District and Haliburton County, passing by many lakes along the way. I stopped in towns such as Dorset, Haliburton and Bancroft before making a beeline down to Belleville and then over th...

Ghost Town Tuesday; Nichols, FL

A couple years ago I spent a lot of spare time exploring phosphate mining ghost towns in the Bone Valley of Polk County, Florida.  One ghost town in particular called Nichols on Polk County Route 676 west of Mulberry caught my eye due to a relative lack of documentation on ghosttowns.com. Nichols was created in 1905 during the early phosphate mining boom in the Bone Valley region.  For the time Nichols was unusual since it had company housing in the Nichols Mine site and private residences outside the gate.  Nichols is only about two miles west of Mulberry which probably made it a somewhat reasonable commute even by the wonky standards of the early 20th Century.  Most of the Bone Valley region was relatively remote which made commuting or homesteading impractical which is why there are so many ghost towns in the area.  The company housing section of Nichols was phased out and abandoned by 1950. The Nichols town site is largely abandoned and could "possibl...
