The Putah Creek Bridge of Monticello (former California State Route 28)

The Putah Creek Bridge was a masonry structure constructed during 1896 by Napa County to serve the community of Monticello.  The Putah Creek Bridge would be annexed into the State Highway System in 1933 when Legislative Route Number 6 was extended from Woodland Junction to Napa.  The Putah Creek Bridge was a component of the original California State Route 28 from 1934-1952.  The span briefly became part of California State Route 128 in 1953 until the highway was relocated as part of the Monticello Dam project in 1955.  Today the Putah Creek Bridge sits at the bottom of the Lake Berryessa reservoir and is accessible to divers.  Pictured as the blog cover is the Putah Creek Bridge as it was featured in the September 1950 California Highways & Public Works.

The history of the Putah Creek Bridge

The site of Monticello lies under the waters of the Lake Berryessa reservoir in what was once known as Berryessa Valley.  The Berryessa Valley name is derived from the Berryessa family which was granted the lands of Rancho Las Putas by Mexican Governor Manual Micheltorena during 1843.  The Berryessa sold their stake in Rancho Las Putas to American investors during 1853.  

Rancho Las Putas was subdivided during 1866 and the farming community of Montecillo was plotted.  By 1870 a franchise wagon road from Napa was constructed via a new bridge over Putah Creek.  By 1875 Napa County purchased the road connecting Napa-Monticello and declared it a public highway.  The highway connecting Napa-Monticello can be seen on the 1882 Bancroft's Map of California.  

The history of the Putah Creek Bridge was featured in the September 1950 California Highways & Public Works Centennial Edition.  The Putah Creek Bridge was referenced in the issue as being a notable example of a masonry bridge in the State Highway System (then part of California State Route 28 and Legislative Route Number 6).  The Putah Creek Bridge was constructed during 1896 by Napa County. The structure was cut from native sourced sandstone and was 70 feet long. The article notes the Putah Creek Bridge was subject to being inundated if the construction of Monticello Dam proceeded.





During 1933 Legislative Route Number 6 (LRN 6) was extended from Woodland Junction to Napa by way of Monticello. The extension of LRN 6 annexed the Putah Creek Bridge into the State Highway System.

The initial run of Sign State Routes was announced in the August 1934 California Highways & Public Works.   The Putah Creek Bridge was assigned as a component of the original California State Route 28 which utilized LRN 6 in the Monticello area.  


California State Route 28/LRN 6 can be seen crossing the Putah Creek Bridge near Monticello on the 1935 Division of Highways Map of Napa County.

The May/June 1953 California Highways & Public Works announced that California State Route 28 was redesignated as California State Route 128.  The California State Route 28 designation was moved to the north shore of Lake Tahoe to be continuous with the long existing Nevada State Route 28.  


The March/April 1955 California Highways & Public Works depicts the progress of the realignment of California State Route 128/LRN 6 at the site of the 270-foot-high Monticello Dam.  The Monticello Dam project broke ground in 1953 along Putah Creek with the end goal of creating the Lake Berryessa Reservoir.  The construction of Monticello Dam required both California State Route 37 and California State Route 128 be realigned to the south of the planned Lake Berryessa.   California State Route 128/LRN 6 in particular was heavily impacted by the Monticello Dam project as it followed Putah Creek from the outskirts of the Town of Monticello east to the Yolo County Line.  Additionally, the Town of Monticello in Berryessa Valley was slated to be inundated by 100 feet of water.  In total 16.3 miles of new highway was slated to be constructed which was largely comprised of a realigned California State Route 128.  The realigned California State Route 128 would make a brief swing into Solano County near the site of Monticello Dam.   Monticello Dam was topped out during November of 1957, but Lake Berryessa wouldn't fill to capacity until April of 1963.



The newly realigned California State Route 128/LRN 6 south of the planned Lake Berryessa appears on the 1956 Division of Highways State Map.  


The former site of Monticello and location of Putah Creek can be seen on the 1959 United State Geological Survey map of Lake Berryessa.  The Putah Creek Bridge was not demolished during the Monticello Dam project and generally is located 100 feet beneath the waters of Lake Berryessa.  


The Putah Creek Bridge has become a well-known dive site at Lake Berryessa.  Underwater footage from the Putah Creek Bridge can be seen below as it was presented on YouTube in 2011.

Crescent City Connection (New Orleans, LA)

The Crescent City Connection is a massive dual-span steel truss bridge that spans the lower Mississippi River at downtown New Orleans, about 95 river miles upstream from the mouth of the great river at the Head of Passes Light. If counted as a single bi-directional highway bridge, the parallel spans combine to form the single busiest bridge on the Mississippi River and its importance as a linchpin in the region’s transportation network cannot be overstated. While there have been various schemes over the years to construct bridges downriver from Algiers Point, this bridge has been the southernmost bridge on the Mississippi River since its initial construction in the 1950s. The years immediately following the end of World War II were a transformational period in the history of New Orleans. Already one of the great economic and cultural centers of the American Deep South, it was recognized at this time that major changes and improvements to the city’s transportation infrastructure would b...

Old US Route 99 through Tipton, Tulare, and Tagus Ranch

This summer I had a look into the alignment history of US Route 99 through the Tulare County communities of Tipton, Tulare, and Tagus Ranch.  While this slab below might seem like much it is one of the few remaining reminders of how US Route 99 was during the 1920s in Tulare County. This blog is part of the larger Gribblenation US Route 99 Page.  For more information pertaining to the other various segments of US Route 99 and it's three-digit child routes check out the link the below. Gribblenation US Route 99 Page Part 1; the history of US Route 99 in Tipton, Tulare, and Tagus Ranch Tipton and Tulare were both founded in 1872 as sidings of the Southern Pacific Railroad.  The Southern Pacific Railroad laid the groundwork for development of southern San Joaquin Valley.  Previous to the Southern Pacific Railroad travel via wagon or foot in Central California tended to avoid San Joaquin Valley in favor of the Stockton-Los Angeles Road.  The Stockton Los Ange...

Former US Route 101 and California State Route 41 through Paso Robles

Paso Robles is a city located on the Salinas River of San Luis Obispo County, California.  As originally configured the surface alignments of US Route 101 and California State Route 41 converged in downtown Paso Robles.  US Route 101 originally was aligned through Paso Robles via Spring Street.  California State Route 41 entered the City of Paso Robles via Union Road and 13th Street where it intersected US Route 101 at Spring Street.  US Route 101 and California State Route 41 departed Paso Robles southbound via a multiplex which split near Templeton.   Pictured above is the cover of the September/October 1957 California Highways & Public Works which features construction of the Paso Robles Bypass.  Pictured below is the 1935 Division of Highways Map of San Luis Obispo County which depicts US Route 101 and California State Route 41 intersecting in downtown Paso Robles.   Part 1; the history of US Route 101 and California State Route 41 i...
