California State Route 227

After taking California State Route 46 west to US 101 I continued south to San Luis Obispo to give California State Route 227 a try.






CA 227 is a 14 mile state highway entirely located within San Luis Obispo County.  The north terminus of CA 227 is at US 101 in the City of San Luis Obispo which can be accessed at exit 201.  CA 227 southbound begins on Madonna Road which heads further into San Luis Obispo.







CA 227 South takes a quick left on Higuera Street before swinging right on South Street.






CA 227 South makes another right on Broad Street which finally takes the route in an actual southward direction.





At the city limits of San Luis Obispo CA 227 passes by the San Luis Obispo County Regional Airport.


CA 227 crosses through the community of Edna which is located alongside a series railroad tracks.  CA 227 ascends over the rails on an overpass but it appears the highway originally crossed on Los Ranchos Road.  Edna dates back to the 1880s when it was built as a company town to house workers on a local ranch.





South of Edna CA 227 runs on Carpenter Canyon Road through the hills towards the City of Arroyo Grande.







CA 227 South takes  left onto Printz Road where it enters the City of Arroyo Grande.



CA 227 South crosses a small bridge before merging onto Corbett Canyon Road.


CA 227 South merges onto Branch Street where it continues through downtown Arroyo Grande to it's terminus at US 101.   There are a series of California Highway Shields in downtown Arroyo Grande lacking the state name in the crest.  Arroyo Grande dates back to 1862 and Branch Street was always the heart the community.  It appears US 101 used Branch Street originally before it blown out to the freeway it now occupies.






CA 227 was not one of the original Signed State Highways and was first signed in 1964 being created out of what was Legislative Route 147.  The change from LRN 147 to CA 227 can be seen by comparing the 1963 and 1964 State Highway Maps.

1964 State Highway Map

LRN 147 doesn't appear to be substantially different than modern CA 227.  Aside from the route alignment difference in Edna I noted above much of the roadway is the same as it when LRN 147 was adopted in 1933.  The north terminus of LRN 147 appears to have met US 101 along Broad Street at Marsh Street.  The southern terminus of LRN 147 appears to have been on Branch Street where US 101 would have taken over possibly at what is now traffic way.  The original alignment of LRN 147 can be seen on the 1935 California Division of Highways map of San Luis Obispo County.

I can't find a map reference where this is apparent but CAhighways.org states that by 1967 there was a proposed extension of CA 227 to CA 1 which was never built.

Mineral King Road, the White Chief Mine, and the unbuilt California State Route 276

Back in July of 2016 I took Mineral King Road east from California State Route 198 to Mineral King Valley within the Sierra Nevada Mountains of Sequoia National Park.  This June I revisited Mineral King Valley and made my way up to the White Chief Mine.


Mineral King Road is a 24.8 mile rural highway maintained by the National Park Service and as Tulare County Mountain Road 375.  Mineral King Road originates at California State Route 198 in Three Rivers near the confluence of the Middle Fork Kaweah River and the East Fork Kaweah River.  Mineral King Road climbs from a starting elevation of 1,400 feet above sea level to 7,830 feet above sea level at the White Chief Mine Trailhead in Mineral King Valley.  Notably Mineral King Road is stated to have 697 curves.


Mineral King Road has an average grade of 5.1% but has several stretches between 15-20% in places.  Pjammycycling has a detailed breakdown on the grade levels over the entirety of Mineral King Road.

Hetch Hetchy Valley; Hetch Hetchy Railroad, abandoned Lake Eleanor Road, and the Wapama Fall Bridge

This June I took a trip out to Yosemite National Park upon receiving my COVID-19 Day Use Reservation.  My destination in Yosemite National Park was out in Hetch Hetchy Valley.  I sought to hike to the Wapama Fall Bridge which took me through some of the path of the former Hetch Hetchy Valley Railroad and abandoned Lake Eleanor Road.



Part 1; Hetch Hetchy Valley, the Hetch Hetchy Railroad, and reservoir roads

Hetch Hetchy is glacially carved valley similar to Yosemite Valley which is located on the Tuolumne River of Tuolumne County.  Hetch Hetchy Valley presently is impounded by the O'Shaughnessy Dam which was completed during 1923 as part of a project to deliver water and hydroelectric power to the City of San Francisco.  Before being impounded Hetch Hetchy Valley had an average depth of approximately 1,800 feet with a maximum depth of approximately 3,000 feet.  Hetch Hetchy Valley is approximately three miles long and as much as a half mile wide.  Hetch Hetchy Valley is located dow…

California's Rogue Sign State Route Shields

While recently revisiting Yosemite National Park I took a couple minutes to capture some of the California Sign State Route shields posted by the National Park Service ("NPS").  None of the NPS shields were actually posted on roadways maintained by Caltrans but were clearly intended to create route continuity with the Sign State Highways.  This phenomenon is not exclusive to Yosemite National Park and can be found on numerous roads not maintained by Caltrans throughout California.



Part 1; Route continuity over who maintains the route

In the very early era of State Highways in California the Division of Highways didn't actually field sign the Auto Trails or even US Routes.  The responsibility of Highway signage fell to the California State Automobile Association ("CSAA") and Automobile Club of Southern California ("ACSC").  The Auto Clubs simply signed Highways on roadways that best served navigational purposes.  These navigational purposes often didn&#…
