California State Route 135

After completing California State Route 227 I headed south into Santa Barbra County to check out an old alignment of US 101 which is now partially incorporated into California State Route 135.






CA 135 is a 21 mile state highway looping from US 101 in Santa Maria southeast to Los Alamos.  As stated above the alignment of CA 135 was largely part of early US 101 which was replaced in the 1930s.  CA 135 is signed along Broadway in Santa Maria and is co-signed as the US 101 Business Route within the city.






CA 135 has a junction with CA 166 in downtown Santa Maria.  Interestingly there is a large pedestrian bridge south of the CA 166 junction on CA 135.





CA 135 crosses a set of rails in downtown Santa Maria and approaches Betteravia Road where it once met former CA 176.  CA 176 was a short route which ended in Sisquoc to the east.






CA 135 becomes an expressway exiting Santa Maria on the approach southward to Orcutt.  The original alignment of CA 135 and US 101 would have been on Orcutt Road which is a front road east of the modern expressway.






In Orcutt CA 135 becomes a freeway.  The freeway grade of CA 135 closely follows the original alignment of US 101 which was on Graciosa Road which runs next to the northbound lanes.







CA 135 merges in with CA 1 at this overpass.  There is no access for CA 135 southbound traffic to merge onto CA 1 north.





CA 135 is briefly multiplexed with CA 1.  The CA 135 freeway segment largely exists to flow traffic to Vandenberg Air Force Base.  Vandenberg traffic continues southward towards Lompoc on CA 1 whereas as CA 135 continues south towards Los Alamos.






South of CA 1 the alignment of CA 135 merges back down to two-lanes and continues southeast towards Los Alamos. 







CA 135 becomes Bell Street in Los Alamos.  Bell Street is directly aligned with the US 101 expressway west of Los Alamos which indicates to me that it was likely part of the 1930s realignment.  




Los Alamos was founded in 1876 out of various ranch land parcels.  Centennial Street was plotted as the main North/South street in Los Alamos due to the community being founded on the American Centennial.  Bell Street carries CA 135 through the community to the to the US 101 expressway where the route ends on San Antonio Boulevard.




As stated above CA 135 was originally a segment of US 101 from Santa Maria to Los Alamos.  It appears that US 101 shifted to the modern expressway alignment some time between 1930 and 1932 as a new state highway can be seen by comparing the two state highway maps from those years.  US 101 stayed on Broadway in Santa Maria but entered the city on Santa Maria Way.



The full modern expressway bypass of Santa Maria that US 101 utilizes first appears on the 1963 State Highway Map.  Interestingly it appears that all of the former routing of US 101 between Los Alamos and Santa Maria remained a branch of Legislative Route 2 until the 1964 State Highway Renumbering.  The change of alignment of US 101 can be seen on the 1963 State Highway Map and the change to CA 135 appears on the 1964 State Highway Map. 



The 1966 State Highway Map shows an expressway alignment of CA 135 south of Santa Maria.  CA 1 is still shown on the Harris Grade southward to Lompoc.

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

Huey P. Long Bridge (New Orleans, LA)

Located on the lower Mississippi River a few miles west of New Orleans, the Huey P. Long Bridge is an enormous steel truss bridge that carries both road and rail traffic on an old-time structure that is a fascinating example of a bridge that has evolved in recent years to meet the traffic and safety demands of modern times. While officially located in suburban Jefferson Parish near the unincorporated community of Bridge City, this bridge’s location is most often associated with New Orleans, given that it’s the largest and most recognizable incorporated population center in the nearby vicinity. For this reason, this blog article considers the bridge’s location to be in New Orleans, even though this isn’t 100% geographically correct. Completed in 1935 as the first bridge across the Mississippi River in Louisiana and the first to be built in the New Orleans area, this bridge is one of two bridges on the Mississippi named for Huey P. Long, a Louisiana politician who served as the 40th Gove
