The rogue G28-1 California State Highway Spades

In this short blog we look at the somewhat rare but not unheard of rouge G28-1 California State Highway Spades.

Part 1; what is the G28-1 California State Highway Spade?

The Caltrans Manual of Uniform Traffic Control Devices Sign Chart from 2014 ("Caltrans MUTCD") dictates the types of signs and highway shields permitted for traffic control use in California. California is known for it's more ornate cut-out shields which are used for; US Routes, Interstate Highways, and State Routes. The common shields which are typically found through California are:

US Route: G26-2

Interstate: G27-2

State Highway: G28-2

The Caltrans MUTCD provides alternative shields for; US Routes, Interstate Highways, and State Routes. These alternative shields are intended for guide sign usage but aren't explicitly limited to said function. These alternative shields are:

US Route: G26-1

Interstate: G27-1

State Highway: G28-1

The primary reassurance shields for; US Routes, Interstate Highways, and State Highways can be seen depicted below.

Part 2; the rogue G28-1 California State Highway Spades

While in theory the G26-1 US Route Shield and G27-1 Interstate Shield could possible see a non-guide sign reassurance shield use I personally haven't encountered any on the road Conversely I have encountered numerous G28-1 State Highway Spades in use as reassurance shields. I have also acquired several G28-1 California State Highway Spades in my signage collection.

The cover to this blog is an unused G28-1 California State Route 14 ("CA 14") shield I have in my sign collection. This CA 14 is tiny as it measures only 18x18 inches.

I also have a G28-1 style CA 135 shield which can be identified as intended for assurance use given it has two mounting holes. This shield is an older variant which is comprised from reflective paint with vinyl numerals.

In terms of field signage this G28-1 CA 227 shield can be found near Arroyo Grande.

This G28-1 CA 180 shield was found on Whites Bridge Avenue (former CA 180) west of downtown Fresno.

This G28-1 CA 270 shield once served as the first westbound reassurance shield as Bodie Road transitions from State Park maintenance to Caltrans maintenance. Unfortunately this shield was missing upon my last visit to Bodie State Historic Park.

G28-1 shields can be found in use in Yosemite National Park on El Portal Road and the Big Oak Flat Road. CA 140 is marked on El Portal Road whereas CA 120 is marked on the Big Oak Flat Road and Tioga Pass Road.

Know of any other G28-1 State Highway Shields in use around California for reassurance purposes? Know of any G26-1 US Route Shields or G27-1 Interstate Highway Shields in use for reassurance purposes? If so please feel free to share in the comments, we would love to hear from you.

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

The original alignment of California State Route 33 in Firebaugh

Firebaugh is a city located on the San Joaquin River of western Fresno County. Firebaugh is one of the oldest American communities in San Joaquin Valley having been settled as the location of Firebaugh's Ferry in 1854. Traditionally Firebaugh has been served by California State Route 33 which was one of the original Sign State Routes announced during August 1934. In modern times California State Route 33 is aligned through Firebaugh on N Street. Originally California State Route 33 headed southbound passed through Firebaugh via; N Street, 8th Street, O Street, 12th Street, Nees Avenue and Washoe Avenue. The blog cover depicts early California State Route 33 near Firebaugh crossing over a one-lane canal bridge. The image below is from the 1935 Division of Highways Map of Fresno County which depicts the original alignment of California State Route 33 in Firebaugh.

Driving the Watkins Glen Historic Road Course - New York

Situated at the south end of Seneca Lake in the Finger Lakes region of Upstate New York, Watkins Glen is well known for wineries along Seneca Lake and waterfalls at Watkins Glen State Park . But one thing that gives the town much renown is its connection to the world of auto racing. The raceway at Watkins Glen Internationa l holds a number of big races every year, such as Six Hours at the Glen and the NASCAR Cup Series . The history of auto racing at Watkins Glen starts during the 1940s when the race followed a course on local roads and also through the streets of downtown Watkins Glen. It's a course that you can follow today, preferably at a more moderate speed than the auto racers of yore raced at. Let's explore the history of the original course, how it came to by and why it is no more. Organized races through the village of Watkins Glen and surrounding roads were first proposed and started by Cameron R. Argetsinger in 1948, marking the beginning of post-war sports car

As I understand it, the G28-1 signs in Yosemite National Park aren't really used for "reassurance", since the state highways shown on those signs don't officially exist within the park, but rather end at the park boundaries. This is reflected in the legislative definitions of those routes, and Caltrans' Postmile Query Tool.

Those signs within the park seem intended to help park visitors reach the state highways outside the park.

With CA 120 and 140 in Yosemite that is an interesting topic. 120 definitely signed enough that one could infer that it is continuous through the Park on the Tioga Pass Road and Big Oak Flat Road. With 140 it’s original 1934 definition had it use El Portal Road and the Old Big Oak Flat Road through the Park to reach CA 120 on what is now Evergreen Road (the Old Tioga Road) just outside the Yosemite boundary. I’ve been trying to find photos for years which might show CSAA 140 shields in Yosemite on the Big Oak Flat Road, thus far to no avail.

I know of one location with some rogue G28-1 signs that was actually only posted this year, and it even has two since it happens to be on a concurrency! It's on CA 36/89 just east of the CA 89 turnoff for Lassen National Park and Morgan Summit, where a realignment project was just completed. Unfortunately I only seem to have managed to get a picture of the back of the sign assembly, but you can at least see it has the different shape of the G28-1 compared to the G28-2: https://www.flickr.com/photos/184498735@N04/50379707676/in/dateposted-public/

There's a couple G28-1 style CA-58 signs at the Mojave/CA City Blvd overpass and freeway entrance.
