California State Route 114

Continuing from the previous blog entry on California State Route 109 a block to the west on Willow Road is California State Route 114.

Since CA 114 and CA 109 are closely related to the realignment of CA 84 I thought that I would link the CA 109 blog here.

California State Route 109

CA 114 is a 1 mile state highway beginning at CA 84 near the approach to the Dumbarton Bridge in Menlo Park south to US Route 84 in East Palo Alto. CA 114 is currently unsigned but wasn't always the case. Heading southbound from CA 84 on CA 114 the company headquarters for Facebook is can be seen directly north of Willow Road.

CA 114 south quickly crosses a series of rail tracks and enters East Palo Alto near O'Brien Drive.

CA 114 was the original alignment of CA 84 which is best evidenced by this CA 84 west shield still posted on the highway. CA 84 was realigned in 1984 when the current Dumbarton Bridge replaced the 1927 span which in turn led to CA 114 being designated on Willow Road.

CA 114 used to have a single shield which could be seen from southbound US 101 approaching Willow Road. The ramp for US 101 is currently undergoing repairs which led to the demise of the CA 114 shield. CA 114 has a southern terminus at US 101.

The routing of CA 114 was originally part of Legislative Route 107 which was extended from US 101 south to the planned alignment of I-280 in 1963 according to CAhighways.org.

It appears that LRN 107 was planned to extend as far south as CA 5 (modern CA 35) when it was designated in 1963 as it can be seen on the State Highway City Insert from said year.

By 1964 the planned segment of LRN 107 south of US 101 was renumbered to LRN 84. It appears that CA 84 was planned to have a much different alignment than the modern one. The changes can be seen on the 1964 State Highway Map City insert. Interestingly the modern route of CA 84 appears as LRN 114.

By 1970 LRN 84 was cut back to I-280. It appears CA 84 was intended to multiplex I-280 west to Woodside.

1970 State Highway Map

As state above the new Dumbarton Bridge was opened to traffic in 1984 which led to the current alignment of CA 84 being created along with CA 114 and CA 109. CA 114 appears on the 1986 State Highway Map with a proposed extension south still to I-280.

According to CAhighways on the above link the extension of CA 114 south to I-280 was abandoned in 1990.

Below the only known CA 114 shield ever to exist can be seen on this Google Car Image.

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
