California State Route 117 (i)


The original California State Route 117 was a segment of Junipero Serra Boulevard from Crystal Springs Road in San Bruno north to Interstate 280 in Daly City.  The corridor of Junipero Serra Boulevard reached San Bruno by 1952 via development as part of Joint Highway District Number 10.  During 1956 Junipero Serra Boulevard was added to the State Highway System as part of Legislative Route Number 237.  The adopted corridor the Junipero Serra Freeway and Interstate 280 north of San Bruno was selected by the California Highway Commission during 1960.  This action led to existing Junipero Serra Boulevard being reassigned as California State Route 117 as part of the 1964 State Highway Renumbering.  California State Route 117 was deleted during 1965 and Junipero Serra Boulevard was reassigned as a placeholder routing for Interstate 280 until the completion of the Junipero Serra Freeway north of San Bruno during 1970.  The original California State Route 117 can be seen as it was displayed on the 1964 Division of Highways Map in the blog cover photo.  


The history of the original California State Route 117

What was to become California State Route 117 was added to the State Highway System as part of 1956 Legislative Chapter 63.  Legislative Chapter 63 defined Legislative Route Number 237 (LRN 237) as:

"Junipero Serra Boulevard as it exists and as it was constructed by Joint Highway District No. 10 from its junction with LRN 56 (California State Route 1) in Daly City to the present terminus of said highway in the City of San Bruno.  Upon the effective date of this section, the Joint Highway District No. 10 shall be dissolved in accordance with the provisions of Chapter 20 of Part 1 of Division 16 of the Streets and Highway Code and all property, assets, and liabilities of said district shall become property of the State."

Junipero Serra Boulevard appears as LRN 237 for the first time on the 1957 Division of Highways Map


The March/April 1957 California Highways & Public Works announced the addition of LRN 237 to the State Highway System.  Upon Joint Highway District Number 10 being dissolved during July 1956 the entirety of Junipero Boulevard was adopted by the California Highway Commission and declared designated a future freeway corridor (the Junipero Serra Freeway).



The March/April 1959 California Highways & Public Works announced the planned Junipero Serra Freeway from the end of Junipero Serra Boulevard/LRN 237 near San Bruno Avenue and Saratoga Avenue in Santa Clara had been adopted by the California Highway Commission as part of LRN 239 (defined in 1957) on July 23, 1958.  The prospective relocation of LRN 237 onto an adopted freeway corridor is noted to be in the process of study.  


The southern terminus of LRN 237 is shown connected to the adopted Junipero Serra Freeway corridor of LRN 239 on 1960 Division of Highways Map.  

The March/April 1960 California Highways & Public Works announced the relocation LRN 237 was discussed at a series of public hearings during January 1960.  


The January/February 1962 California Highways & Public Works discussed the history of Joint Highway District Number 10.  Joint Highway District Number 10 was created during 1928 as a cooperative between San Francisco County and San Mateo County.  The purpose of the district was to ultimately construct a new arterial highway from San Franscico south to San Jose.  By 1939 the district had located an alignment for Junipero Serra Boulevard as far south as Santa Clara County line.  Junipero Serra Boulevard had constructed to Crystal Springs Road by 1952 via right-of-way largely obtained in Millbrae.  Joint Highway District Number 10 began to encounter financial difficulties and issues finding a suitable alignment which led to Junipero Serra Boulevard being turned over to the state as LRN 237 during 1956.  The general routing of the Junipero Serra Freeway (Interstate 280) following LRN 237/existing Junipero Serra Boulevard north of San Bruno is noted to have been adopted by the California Highway Commission during 1960.  






As part of the 1964 State Highway Renumbering what had been LRN 237 along Junipero Serra Boulevard was defined as California State Route 117.  California State Route 117 was defined as "Crystal Springs Road in the city of San Bruno northerly to Route 280 in Daly City."  The adopted Junipero Serra Freeway corridor north of San Bruno was defined as part of legislative definition of Interstate 280.  California State Route 117 appears for the first time on the 1964 Division of Highways Map.  

The original California State Route 117 was deleted by way of 1965 Legislative Chapter 1372.  Junipero Serra Boulevard north of San Bruno was transferred legislatively as Route 280 which functioned as a placeholder connection for Interstate 280.  Junipero Serra Boulevard north of San Bruno can be seen as part of Route 280 on the 1966 Division of Highways Map.  Junipero Serra Boulevard was relinquished from the State Highway System during 1970 following the completion of Interstate 280 on the Junipero Serra Freeway north of San Bruno.

Horace Wilkinson Bridge (Baton Rouge, LA)

Standing tall across from downtown Baton Rouge, the Horace Wilkinson Bridge carries Interstate 10 across the lower Mississippi River between West Baton Rouge and East Baton Rouge Parishes. Unusually, the bridge is actually named for three separate people; three generations of Horace Wilkinsons who served in the Louisiana State Legislature over a combined period of 54 years. Constructed in the 1960s and opened to traffic in 1968, this is one of the largest steel bridges on the lower Mississippi. It’s also the tallest bridge across the Mississippi, with its roadway reaching 175 ft at the center span. Baton Rouge is the northernmost city on the river where deep-water, ocean-going vessels can operate. As a result, this bridge is the northernmost bridge on the river of truly gigantic proportions. Altogether, the bridge is nearly 2 ½ miles long and its massive truss superstructure is 4,550 ft long with a center main truss span of 1,235 ft. The Horace Wilkinson Bridge is one of the largest

Sunshine Bridge (Donaldsonville, LA)

Located about halfway between Baton Rouge and New Orleans in southern Louisiana, the Sunshine Bridge spans the lower Mississippi River near the city of Donaldsonville as part of the longer Louisiana Highway 70 corridor, which connects Interstate 10 and Airline Highway (US 61) with US 90 in Morgan City. In the years following World War II, the only bridges across the lower Mississippi River in Louisiana were located in the area of the state’s two largest cities – Baton Rouge and New Orleans. Postwar agricultural and industrial development along the river in this region led to the planning of a series of infrastructure projects in southern Louisiana that were aimed at spurring this development and modernization of the Delta region. One of these projects was known as the Acadian Thruway and was developed in the 1950s as a toll road intended to connect greater New Orleans with Lafayette and points west while providing a high-speed bypass of the Baton Rouge metro area. The Thruway, which

Natchez-Vidalia Bridge (Natchez, MS)

  Located about halfway between Baton Rouge and Vicksburg near the city of Natchez, the Natchez-Vidalia Bridge crosses the lower Mississippi River between southwest Mississippi and northeastern Louisiana at the city of Vidalia. This river crossing is a dual span, which creates an interesting visual effect that is atypical on the Mississippi River in general. Construction on the original bridge took place in the late 1930s in conjunction with a much larger parallel effort by the U.S. Army Corps of Engineers to strengthen the area’s flood protection and levee system along the Mississippi River. One of the more ambitious aspects of this plan was to relocate the city of Vidalia to a location of higher ground about one mile downriver from the original settlement. The redirection of the river through the Natchez Gorge (which necessitated the relocation of the town) and the reconstruction of the river’s levee system in the area were undertaken in the aftermath of the Great Flood of 1927, wh
