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.

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.   ...

Three Points Road (Los Angeles County)

Three Points Road is a rural cutoff route which connects Pine Canyon Road (Los Angeles County Route N2) and California State Route 138 near Neenach of Antelope Valley.  Originally the community of Three Points (named for the junction Pine Canyon, Oakdale Canyon and Oakgrove Canyon) was served by 265th Avenue West.  The modern three-mile-long corridor of Three Points Road was developed by 1950 to serve as a softer transition to California State Route 138.  Part 1; the history of Three Points Road Three Points Road is named in reference to the community near the extinct Neenach Volcano known as Three Points.  Three Points itself is a reference to three canyons it sits in the middle of: Pine Canyon, Oakgrove Canyon and Oakdale Canyon.  Three Points was homesteaded by the Laffery family in 1892.  Nearby Gookins Lake was named after one of the Laffery family members.   Three Points (blue pin) can be seen at the intersection of Pine Canyon Road (now Los...

Hawaii Route 50

Hawaii Route 50 is the longest Sign Route on the island of Kauai at 32.6 miles.  The entirety of Hawaii Route 50 is overlaid atop Kaumualii Highway from Lihue west to the Pacific Missile Range Facility at Barking Sands. Hawaii Route 50 is one of the original 1955-era State Highway designations on Kauai.  Much of the Kaumualii Highway corridor was constructed during the sugar plantation boom of the late Hawaiian Kingdom.  The first tee beam bridge in Hawaii would be constructed along the Kaumualii Highway in 1911 at the Hanapepe.  Much of this highway would be modernized to two-lane standards through the 1930s and 1940s.
