Western California State Route 16

The western segment of California State Route 16 is a largely scenic corridor which follows Cache Creek for much of it's alignment. 

Present California State Route 16 ("CA 16") is a 82 mile State Highway which exists in two segments.  Segment one of CA 16 is routed between CA 20 east to Interstate 5 ("I-5) near Woodland.  Segment two of CA 16 exists from US Route 50 ("US 50") near Perkins east to CA 49 near Drytown.  The focus of this blog will be on the western segment of CA 16.  

Pertaining to the relinquished central segment of CA 16 in the greater Sacramento area more information can be found on the blog below:

Highways in and around Old Sacramento; US 40, US 99W, CA 16, CA 24, CA 70, CA 99, CA 275, and more

 

Part 1; the history of the western segment of California State Route 16 

The predecessor to CA 16 was what would become Legislative Route Number 50 ("LRN 50") which was first added to the State Highway System as a survey ordered by the State of California as part of 1915 Legislative Chapter 283:

"commencing at the town of Rumsey, in the county of Yolo and following generally the meanderings of Cache Ck...to the town of Lower Lake, in the county of Lake"

Said survey between Rumsey and Lower Lake appears to not have had a clear routing as it does not appear on the 1918 Division of Highways State Map.

As part of the 1919 Third State Highway Bond Act LRN 50 was formally defined as a highway between Rumsey and Lower Lake.  Both LRN 50 and LRN 49 appear on the 1920 Division of Highways State Map as a continuous State Highway west from Rumsey west to Lower Lake then southward to Calistoga.  The route of LRN 50 does not appear to correspond to an actual roadway as it is shown following the main flow of Cache Creek northeast from Lower Lake to the confluence of Cache Creek and North Fork Cache Creek.  Even the road east of the confluence of North Fork Cache Creek/Cache Creek does not correspond to a roadway that was ever constructed. 

The 1922 Division of Highways Map shows the planned route of LRN 50 between Lower Lake and Rumsey taking a more southern angle way from the confluence of Cache Creek/North Fork Cache Creek.


The 1926 Division of Highways State Map shows LRN 50 was realigned north of Lower Lake to LRN 15.  LRN 50 followed LRN 15 east to Wilbur Spring where it split southeast towards Rumsey.

The January/February 1929 California Highways & Public Works described LRN 50 between Wilbur Springs and Rumsey as not constructed.  There is a brief citation which states that LRN 50 would likely be built on a new grade which would not incorporate the existing road between Wilbur Springs and Rumsey.   

The 1930 Division of Highways State Map subsequently only shows a couple miles of LRN 50 south of LRN 15 constructed.  A proposed highway can be seen connecting southward to Rumsey.   

According to CAhighways.org LRN 50 was extended in 1933 east from Rumsey east to LRN 7 in Woodland.  The extension of LRN 50 east from Rumsey to Woodland was announced in the April 1933 California Highways & Public Works.

 
 
The completion of the Rumsey-Clear Lake Highway (LRN 50) is discussed in the August 1934 California Highways & Public Works.  Construction of the Rumsey-Clear Lake Highway is cited to have begun during July of 1930 and concluded with an opening ceremony held on August 4th, 1934. 
 


In the August 1934 California Highways & Public Works the entirety of LRN 50 was announced as a segment of CA 16.  


Oddly CA 16 followed a State Maintained Highway east of Woodland to Sacramento.  LRN 50 was clarified in 1935 when it was codified as a highway between:

"[LRN 15] to Sacramento via Rumsey and Woodland"

LRN 50 between LRN 15 ("CA 20") east to Sacramento can be seen in detail on the 1935 Division of Highways Maps of Colusa County and Yolo County.  East from Woodland LRN 50/CA 16 can be seen following; Main Street, Old River Road, North Harbor Boulevard, Sacramento Avenue, C Street, and Kline Street to the I Street Bridge at the Sacramento River into Sacramento.

The full initial routing of CA 16 can be seen in more clear detail on the 1937 Gousha Highway Map of California.   Note; CA 24 can be seen multiplexing CA 16 from Woodland east to Sacramento.  CA 24 was extended from Woodland to the San Francisco Bay Area in 1935. 

Not much would change with the present western segment of CA 16 until LRN 238 was adopted as the planned route of I-5 between Bakersfield and Woodland in 1957.  Within the Sacramento Area I-5/LRN 238 was planned to follow the eastern bank of the Sacramento River towards Woodland whereas CA 16/CA 24/LRN 50 followed the western bank.  LRN 238 appears as a proposed highway between Sacramento and Woodland on the 1958 Division of Highways State Map.  


By 1960 CA 24 had been rerouted off of CA 16/LRN 50 onto LRN 232 from Maryville-Sacramento.  This shift in CA 24 can be seen on the 1960 Division of Highways State Map.    

 
 
During the 1964 State Highway Renumbering CA 16 between Sacramento-Woodland was legislatively designated as Route 5.  It is likely that CA 16 between Sacramento-Woodland was signed as temporary I-5.  CA 16 was redesignated with two segments; the first being "Route 20 to Route 5 near Woodland via Rumsey and Woodland" and "Route 50 near Perkins to Route 49 near Drytown."  These changes to CA 16 can be seen on the 1964 Division of Highways State Map.  

 
 
CA 16 can be seen partially multiplexing the completed I-5 east of Woodland.  CA 16 is seen splitting from I-5 towards Old Sacramento via the I Street Bridge on the 1970 Division of Highways State Map

CA 16 would eventually moved to a multiplex of; I-5, I-80, and US 50 from the I Street Bridge through Sacramento to the current eastern segment of the highway.  This multiplex can be seen on the 1975 Caltrans State Map.  

According to CAhighways.org the surface alignment of CA 16 between Woodland-Sacramento (specifically Conaway-Sacamento) and the I Street Bridge were relinquished in 1984.  Regardless CA 16 is still shown multiplexing I-5 between Woodland-Sacramento on the 1986 Caltrans State Map.  

Even the 1990 Caltrans State Highway Map shows CA 16 multiplexed with I-5 between Woodland-Sacramento.  It is unclear what if any field signage existed to indicate a connecting route between the western and eastern segments of CA 16.  

The 1990 Caltrans State Highway Map also shows CA 16 shifting off of Main Street to Road 98 in Woodland.  This lead to the odd circumstance where the western segment of CA 16 and Yolo County Route E7 both terminate at I-5 via Road 98. 


Part 2; a drive on the western segment of California State Route 16

The western segment of CA 16 begins from CA 20 near Bear Creek at Postmile COL 3.45.  


From CA 20 the route ahead on CA 16 eastbound shows Rumsey 15 miles away and Woodland 50 miles away. 

CA 16 east initially follows Bear Creek and is signed with an Elk Advisory for 6 miles. 

CA 16 east follows Bear Creek southeast to the confluence with Cache Creek, at Postmile COL 7.25 CA 16 east enters Yolo County.  Note; CA 16 carries a "D" suffixed Postmile supplement from the Yolo County up to COL D0.632.  The "D" suffix indicates a duplicate Postmile at a meandering county line. 










CA 16 east follows the meanderings of Cache Creek before emerging out of Rumsey Canyon at Postmile YOL 6.291.  The Clear Lake-Rumsey Highway as noted in the August 1934 California Highways & Public Works carries an almost flat grade.  It is likely that CA 16 and the Clear Lake-Rumsey Highway diverged from Cache Creek northwest up Bear Creek due to increasingly difficult terrain due west.














At Postmile YOL 7.14 CA 16 east enters Rumsey.  Rumsey was originally settled in 1878 when it was known as "Rock."  The community moved to the terminus of the Vaca Valley & Clear Lake Railroad in 1888 and was renamed to "Rumsey."  The name "Rumsey" was taken from local land owner Captain D.C. Rumsey.  Much of Rumsey was destroyed following the 1906 San Francisco Earthquake when Cache Creek was dammed by land slide.  When the debris on Cache Creek gave way it flooded the community of Rumsey.  


CA 16 east is signed as 5 miles from Guinda upon leaving Rumsey.

CA 16 east enters Guinda at Postmile 11.977.  Guinda was another siding of the Vaca Valley & Clear Lake Railroad and was directly plotted by the Southern Pacific.  Guinda takes it's name for a cherry tree which was found at the location of the new siding.  Guinda received Post Office Service in 1889. 






Departing Guinda CA 16 east is signed as 14 miles from Capay and 30 miles from Woodland.  

CA 16 east passes by the Cache Creek Casino Resort at Postmile YOL 19.37.






CA 16 enters a 20 miles long Daytime Headlight corridor east of the Cache Creek Casino Resort.  



CA 16 east enters Capay at Postmile YOL 25.79.  Capay takes it's name from the Mexican Land Grant known as Rancho Canada de Capay.  The community of Capay was originally settled in 1857 and came to be known as Munchville (an awesome name taken from the first modern settler).  Munchville eventually became Langville which took it's name from a local hotel owner in the 1870s.  The modern name of Capay was assumed in 1875.





CA 16 east intersects Yolo County Route E4 at Postmile YOL 25.67 in Capay.

Departing Capay CA 16 is signed as 2 miles from Esparto and 16 miles from Woodland. 

CA 16 east enters Esparto at Postmile 26.36 as Woodland Avenue.  




At approximately Postmile YOL 27.67 a box car can be found on CA 16/Woodland Avenue in Esparto.  Esparto was settled as a siding of the Vaca Valley & Clear Lake Railroad in 1888.  Originally Esparto was known as Esperanza.  The community changed it's name upon receiving Post Office Service in 1890 to Esparto as a measure avoid a duplication with a community in Tulare County.  Esparto became the terminus of the Vaca Valley & Clear Lake Railroad in 1943 when the last tracks from Rumsey had been removed.  Passenger Service to Esparto via the Vaca Valley & Clear Lake Railroad was discontinued in 1957. 



At Postmile YOL 27.82 CA 16 east makes a right hand turn onto Yolo Avenue. 

CA 16 follows Yolo Avenue through downtown Esparto and makes a left hand turn at Postmile YOL 28.26 towards Woodland. 



Departing Esparto CA 16 east is signed as 4 miles from I-505 and 14 miles from Woodland. 


CA 16 east passes through Madison via a roundabout at Postmile YOL 31.0.




East of Madison CA 16 intersects I-505.

CA 16 east approaches Woodland where it's Daytime Headlight Corridor terminates.  CA 16 east enters Woodland as Main Street but makes a left hand turn onto Yolo County Route E7/Road 98 at Postmile R40.57.







CA 16 on Road 98 is co-signed with Yolo County Route E7 and I-5 Business. 


CA 16 east, Yolo County Route E7 north, and I-5 Business all follow Road 98 northward a terminus at I-5 located at Postmile YOL R43.42.

Ghost Town Tuesday; Mannfield, FL and the stairway to Hell

Back in 2015 I went searching the Lecanto Sand Hills for the original Citrus County Seat known as Mannfield.  Unlike Centrailia in Hernando County and Fivay in Pasco County I did find something worth seeing. Mannfield is located in the Lecanto Sand Hill section of Withlacoochee State Forest somewhat east of the intersection of Citrus County Route 491 and Mansfield Road. Mannfield was named after Austin Mann and founded in Hernando County in 1884 before Citrus County Split away.  In 1887 Citrus County was split from northern Hernando County while Pasco County was spun off to the south.  Mannfield was selected as the new Citrus County seat due to it being near the county geographic center.  Reportedly Mannfield had as many as 250 people when it was the County Seat.  The town included various businesses one might include at the time, even a sawmill which was common for the area.  In 1891 Citrus County voted to move it's seat to Inverness which set the s...

Interstate 40's Tumultuous Ride Through the Pigeon River Gorge

In the nearly 60 years Interstate 40 has been open to traffic through the Pigeon River Gorge in the mountains of Western North Carolina, it has been troubled by frequent rockslides and damaging flooding, which has seen the over 30-mile stretch through North Carolina and Tennessee closed for months at a time. Most recently, excessive rainfall from Hurricane Helene in September 2024 saw sections of Interstate 40 wash away into a raging Pigeon River. While the physical troubles of Interstate 40 are well known, how I-40 came to be through the area is a tale of its own. Interstate 40 West through Haywood County near mile marker 10. I-40's route through the Pigeon River Gorge dates to local political squabbles in the 1940s and a state highway law written in 1921. A small note appeared in the July 28, 1945, Asheville Times. It read that the North Carolina State Highway Commission had authorized a feasibility study of a "...water-level road down [the] Pigeon River to the Tennessee l...

The mystery of Hawaii Route 144 and temporary Hawaii Route 11

The 1959 Gousha Road map of Hawaii features two largely unknown references in the form of Hawaii Route 144 and Temporary Hawaii Route 11.  Both corridors are shown running from the boundary of Hawaii Volcanoes National Park east to Glenwood via Volcano Village.  At the time Hawaii Route 11 was using the so-called "Volcano Road" which was constructed as a modernization of Mamalahoa Highway during 1927-1928.  This blog will examine the two map references and will attempt to determine what they might indicate.  The mystery of Hawaii Route 144 and Temporary Hawaii Route 11 Hawaii Route 11 is part of Mamalahoa Highway (the Hawaii Belt Road) and is the longest Hawaiian State Route at 121.97 miles.  The highway begins at the mutual junction of Hawaii Route 19 and Hawaii Route 190 in Kailua-Kona.  From Kailua-Kona the routing of Hawaii Route 11 crosses the volcanic landscapes of southern side of the Big Island.  Hawaii Route 11 terminates at Hawaii Route 19/Ka...
