Signed County Route J18 and pre-1937 California State Route 140

The fourth route I took this past Monday was Signed County Route J18.






County Route J18 is a 26.5 mile route spanning San Joaquin Valley from I-5 east to CA 99.  From I-5 CR J18 starts at exit 423 along Stuhr Road.







Sturh Road looking east towards Newman across San Joaquin Valley.


J18 crosses CA 33 just north of the city limits of Newman.


East of Newman Sturh Road ends and J18 east takes a left turn on Hills Ferry Road.  Hills Ferry Road quickly crosses the San Joaquin River into Merced County becoming Kelley Road.


CR J18 turns right on River Road over the Merced River.  The 1910 Merced River Bridge is located next to the modern bridge on River Road.  The 1910 bridge is heavily vandalized and obviously not very well cared for with holes in the asphalt surface.  (Post Note; Hard to believe this bridge was on CA 140 after doing map research)













River Road east of the Merced River is in terrible shape and can't really practically be drive at speeds higher than 45 MPH comfortably.  River Road has several 90 degree turns and generally follows the path of the Merced River.





Oddly CR J18 jumps onto CA 165/Lander Avenue briefly before continuing east on Westside Boulevard.



Westside Boulevard is flat and straight with very few indications you are still on CR J18 aside from this weird looking shield.

After 11 miles on Westside Boulevard CR J18 terminates at CA 99 near Atwater.


According to CAhighways.org CR J18 has been signed since 1960.

Interestingly it seems that most of CR J18 was once likely part of CA 140.  The 1935 Division of Highways maps for Stanislaus and Merced Counties show Legislative Route 122 running from CA 33 in Newman east to US 99 in Livingston.  The route of this highway is exactly the same as CR J18 aside from using Main Street north from Westside Boulevard to reach US 99 in Livingston and utilizing Hills Ferry Road to CA 33 in Newman.  I'm uncertain if this stretch was signed as CA 140 but the new section definitely was by 1938.

CA 140 appears on the J18 alignment on the 1936-37 edition of the state highway map but is no longer state maintained on the 1938 map.

CAhighways.org states that CA 140 was moved off the J18 alignment southward in 1937.

California State Route 77; the real "Shortest Signed" State Highway

Over the last two weeks I visited almost every State Highway in the San Francisco Bay Area.  The shortest State Highway by a large margin in the Bay Area is California State Route 77.


CA 77 is presently only 0.45 miles in length and is located entirely within the City of Oakland.  CA 77 begins at Interstate 880 and heads eastward on 42nd Avenue to CA 185 on 14th Street.  As presently completed CA 77 would rank as the third shortest State Highway only behind CA 275 and CA 283.

CAhighways.org list of Shortest State Highways

CA 77 presently has a 13.4 mile portion that has not been constructed.  CA 77 as originally envisioned would have continued northeast towards Concord and would have junctions with; I-580, unbuilt CA 93, CA 24, I-680 and CA 242.  According to CAhighways.org the present route of CA 77 was designated as Legislative Route Number 233 which was approved by the State Legislature in 1953.  The legislative description of LRN 233 was changed to LRN 235 by 1957.

Local Sign Find - Georgia Route 280 found in Sutersville, PA?

Sign errors happen - a US shield in place of a state highway shield or vice versa.  It's interesting to some and a pet peeve to others.  But when Mike Natale found a Georgia 280 shield in Sutersville, Pennsylvania, you have to think something must be up.
And in this case, there's a reason for it.  It's a prop for a television series.  Netflix's popular TV series "Mindhunter" is shot in the Pittsburgh area.   Mike came across the GA 280 sign in October 2018 and it is possible that the scenes involving Georgia 280 should be in Episode 6 or 7.

Georgia State Highway 280 is located in northwestern and western Atlanta.  That's a far cry from the Mon Valley.  It is common for television or movie scenes to be shot elsewhere than where they are set at.  However, it is very rare to see a sign prop out in the wild while production is on going.  This is a great find by Mike!

The strange evolution of Interstate 280 in San Francisco

Recently while in the San Francisco Bay Area I wanted to check out the north terminus of Interstate 280 in downtown San Francisco.  I-280 as currently aligned diverges significantly from what was originally planned in the City of San Francisco.


Much of the finalized planning of the Interstate Highway System in the San Francisco Bay Area was largely plotted out by 1956.  Between CA 17 in Los Gatos and CA 1 in San Francisco the path of I-280 ultimately followed Legislative Route Number 239 which was designated by the State Legislature in 1957.

LRN 239 can be seen appearing on the State Highway Map City Insert of San Francisco connecting to CA 1 by 1958.

I-280 was to take a far different route than it currently does in San Francisco.  The original plan for I-280 was to follow CA 1 on LRN 56 towards the Golden Gate Bridge where it would terminate at I-480/LRN 224 and US 101.  The original planned alignment of I-280 becomes apparen…
