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.

Old NY 10 and Goodman Mountain in the Adirondacks

  Old highway alignments come in all shapes and sizes, as well as taking some different forms after their lifespan of serving cars and trucks has ended. In the case of an old alignment of what was NY 10 south of Tupper Lake, New York, part of the old road was turned into part of a hiking trail to go up Goodman Mountain. At one time, the road passed by Goodman Mountain to the east, or Litchfield Mountain as it was known at the time. As the years passed, sometime around 1960, the part of NY 10 north of Speculator became part of NY 30, and remains that way today from Speculator, past Indian Lake and Tupper Lake and up to the Canadian Border. At one time, the highway was realigned to pass the Goodman Mountain to the west, leaving this stretch of road to be mostly forgotten and to be reclaimed by nature. During the summer of 2014, a 1.6 mile long hiking trail was approved the Adirondack Park Agency to be constructed to the summit of the 2,176 foot high Goodman Mountain. For the first 0.9 mi

Oregon State Highway 58

  Also known as the Willamette Highway No. 18, the route of Oregon State Highway 58 (OR 58) stretches some 86 miles between US 97 north of Chemult and I-5 just outside of Eugene, Oregon. A main route between the Willamette Valley region of Oregon with Central Oregon and Crater Lake National Park, the highway follows the Middle Fork Willamette River and Salt Creek for much of its route as it makes its way to and across the Cascades, cresting at 5,138 feet above sea level at Willamette Pass. That is a gain of over 4,500 in elevation from where the highway begins at I-5. The upper reaches of OR 58 are dominated by the principal pinnacle that can sometimes be seen from the highway, Diamond Peak, and three nearby lakes, Crescent, Odell and Waldo (Oregon's second largest lake). OR 58 is chock full of rivers, creeks, mountain views, hot springs and waterfalls within a short distance from the highway. OR 58 was numbered as such by the Oregon State Highway Department in 1940. OR 58 is a del

Siuslaw River Bridge - US 101 in Florence, Oregon

  As the Oregon Coast Highway (US 101) was being completed across the State of Oregon during the 1930s, a number of bridges needed to be built to cross some of the state's finest rivers. In Florence, Oregon , the Siuslaw River Bridge was designed and constructed to help fill in the gaps between different coastal communities. Built in 1936, the Siuslaw River Bridge is a bascule bridge flanked by two reinforced concrete arches that spans across the Siuslaw River. The bridge and the river get their names from the Siuslaw tribal people who make their home along the river valleys of this part of the Oregon Coast. Today, the bridge provides a vital link connecting US 101 and the Central Oregon Coast to points north and south. The total length of the Siuslaw River Bridge is 1,568 feet, stretching across the river. But more specifically, the bridge is made up of a north approach with eight spans of reinforced concrete deck girder totaling 478 feet in length. There is a main span in three
