California State Route 116

This past month I drove a segment of California State Route 116 from US Route 101 in Cotati east to CA 121 near Schellville. 


CA 116 is a 46 mile east/west State Highway entirely located within Sonoma County.  CA 116 begins near CA 1 in Jenner and travels easterly to a terminus at CA 121.



Part 1; the history of CA 116

What is now CA 116 entered the State Highway System as Legislative Route 104 in 1933 according to CAhighways.org.  LRN 104 between Jenner and Sebastopol was added to Sign Route 12 in 1934.  CA 12 can be seen on LRN 104 between Jenner and Sebastopol on the 1938 Division of Highways State Map.


During the 1964 State Highway Renumbering CA 12 west of Sebastopol was given a new planned alignment that was an unbuilt segment of LRN 51.  All of LRN 104 was redefined with a new designation of CA 116.  CA 116 included a multiplex of US 101 from Cotati south to Petaluma.  The change from LRN 104 to CA 116 can be seen by comparing the 1963 Division of Highways Map to the 1964 Edition.

Part 2; a drive on CA 116 from US 101 in Cotati to CA 121 near Schellville

My approach to eastbound CA 116 was on US 101 south in Cotati.  After an interchange at Exit 481B US 101 south picks up CA 116 east on a multiplex.







Petaluma is signed as 8 miles from Cotati on US 101 south/CA 116 east.


US 101 south/CA 116 east ascends over a small pass before descending into the City of Petaluma.










US 101 south/CA 116 east Exit 476 accesses Old Redwood Highway and Petaluma Boulevard.



US 101 south/CA 116 east next has an Exit at East Washington Street.



CA 116 east splits from US 101 south onto Lakeville Street at Exit 472B.





As CA 116 east exits onto Lakeville Highway there is signage directing traffic to Valejo's Petaluma Adobe.




CA 116 east follows Lakeville Highway to the City Limits of Petaluma where it enters a Safety Corridor.










CA 116 east follows Lakeville Highway to Post Mile SON 39.279 where it makes a left hand turn onto Stage Gulch Road.






CA 116 east ascends through Stage Gulch on the namesake Stage Gulch before making a right hand turn at Old Abode Road at Post Mile SON 41.799.  The climb through Stage Gulch is probably the most interesting part of CA 116 east of US 101 and is actually quite scenic.













CA 116 east follows Stage Gulch Road to approximately Post Mile SON 44.83 where it transitions onto Arnold Drive.












CA 116 east follows Arnold Drive to a terminus at CA 121.

Deer Isle Bridge in Maine

As graceful a bridge that I ever set my eyes upon, the Deer Isle Bridge (officially known as the Deer Isle-Sedgwick Bridge) surprisingly caught my eye as I was driving around coastal Maine one Saturday afternoon. About 35 miles south of Bangor, Maine , the Deer Isle Bridge connects the Blue Hill Peninsula of Downeast Maine with Little Deer Isle over the Eggemoggin Reach on ME 15 between the towns of Sedgwick and Deer Isle . It should be noted that Little Deer Isle is connected to Deer Isle by way of a boulder lined causeway, and there is a storied regatta that takes place on the Eggemoggin Reach each summer. But the Deer Isle Bridge holds many stories, not just for the vacationers who spend part of their summer on Deer Isle or in nearby Stonington , but for the residents throughout the years and the folks who have had a hand bringing this vital link to life.   The Deer Isle Bridge was designed by David Steinman and built by the Phoenix Bridge Company of Phoenixville,

Former US Route 99 through Athlone and the last Wheeler Ridge-Sacramento corridor expressway

Athlone was a siding of the Southern Pacific Railroad located in Merced County on the alignment of what was US Route 99 between the cities of Chowchilla and Merced.  The Athlone corridor of US Route 99 was one of the first in San Joaquin Valley to fully upgraded to four lane expressway standards.  The Athlone expressway corridor was inherited by California State Route 99 when US Route 99 was truncated to Ashland, Oregon during June 1965.  The four-lane expressway through Athlone was the last segment of what had been US Route 99 in the Wheeler Ridge-Sacramento corridor to be bypassed by a freeway.  The Athlone expressway corridor was bypassed by the modern California State Route 99 freeway in 2016.  Despite being put on a road diet and narrowed what was the Athlone expressway corridor still displays evidence of being part of US Route 99.   Above the blog cover photo displays the Athlone expressway corridor of US Route 99 south of Merced as depicted in the July 1939 California Highways &

California State Route 38

California State Route 38 is a fifty-nine-mile State Highway located entirety in San Bernardino County and a component of the Rim of the World Highway.  California State Route 38 begins at California State Route 18 at Bear Valley Dam of the San Bernardino Mountains and follows an easterly course on the north shore of Big Bear Lake.  California State Route 38 briefly multiplexes California State Route 18 near Baldwin Lake and branches east towards the 8,443-foot-high Onyx Summit.  From Onyx Summit the routing of California State Route 38 reverses course following a largely westward path through the San Bernardino Mountains towards a terminus at Interstate 10 in Redlands.   Pictured as the blog cover is California State Route 38 at Onyx Summit the day it opened to traffic on August 12th, 1961.   Part 1; the history of California State Route 38 California State Route 38 (CA 38) is generally considered to be the back way through the San Bernardino Mountains to Big Bear Lake of Bear Valley
