Highway Shields and University Logos

Michigan, Wyoming, and, at one point, North Carolina.  Three states that have or had what appears to be their flagship university's logo within their highway shield.  Is that truly the case?

Within the roadgeek community - specific to those that are more sign enthusiasts - there has been debate on whether or not the three states do, did, or do not use the logo of their state universities in their highway shields.  Some say yes, while others say no.  So, I decided to take a closer look.


M-39 Highway Shield (Tom Fearer)

Big Blue. Trunkline highways which are noted as "M-Route Number."  At first glance, it sure does look like the M in a Michigan highway shield are the same - but when you look closely - they are not.

University of Michigan logo (

The M in the University of Michigan logo is wider, and the point of the M is much lower than that of the Michigan highway shield.  As shown in the illustration below from Chris Bessert at, you can see that the two 'M's do not line up.  They are just different enough.

Even with that, the idea is that the use of the M for Michigan highways came from the university's block 'M.' Again, not really - a quick dive into the history of both 'M's is worth looking at.

The "Block M" of Michigan is to have first debuted on November 16, 1907, at a football game against the University of Pennsylvania. (1) From that point, the "Block M" slowly grew as the symbol of the university and its athletic programs. However, it wasn't until 1948 that the University of Michigan began to showcase the "Block M" in what we would call today its branding.  Over the next few decades, the "Block M" would develop even further as the symbol of the university.  In 1982, the University of Michigan applied for and received a trademark for its "Block M" logo.

Meanwhile, the development of the Michigan highway shield M began with Alan M. Williams with the Michigan State Highway Department.  Williams drafted the first state highway map in 1919, and it is considered that he was instrumental in designing the state highway marker. Williams was a 1916 graduate of the University of Michigan. (2)

In the end, it is just coincidental. The M in the highway shield debuted just as the University's "Block M" began taking hold. However, it was nearly 30 years before the Block M was officially part of the university's logo - and the two shapes are just different enough not to conflict with any trademark issues.


Wyoming Highway Shields (Adam Prince)

The Bucking Horse and Rider. It is synonymous with the State of Wyoming. It is the logo for the University of Wyoming; it's on the state highway shield, and just about anywhere in Wyoming. They are all the same logo, and it is also a trademarked property of the state.

The use of the bucking horse and rider dates to World War I as the insignia worn by members of the Wyoming National Guard serving in France and Germany. (3)  The design is displayed throughout the state - from the university to highway shields and license plates to almost anything. The logo's origin is credited to a photograph of a famous rodeo horse named "Steamboat" taken at the Albany County Fair in 1903.

The University of Wyoming logo (

The University of Wyoming first used the Bucking Horse and Rider for its logo in 1921. By 1936, it was well-known enough to be showcased on the state's license plates and highway shields.  Due to concerns about the counterfeit use of the logo, the state applied for and received a copywrite for the design in 1936. It has been since trademarked as a joint effort between the State of Wyoming and the University of Wyoming.

North Carolina:

NC 150 Cutout shield at the North Carolina Transportation Museum (Adam Prince)

Until the mid-late 1960s, the North Carolina highway shield had an interlocking 'NC' at the top of the diamond above the numerals. And like Michigan's, at first look, it appears to be the same as the logo for the University of North Carolina.  And like Michigan's, it wasn't.

The difference between the two logos is the vertical lines in the letter 'N.' While the NC highway shield N was straight, the UNC 'N' had curved vertical lines.

The 1901-1931 University of North Carolina Logo (

As for what came first, the interlocking NC first appeared as the university's logo as early as the 1890s and has stuck ever since.  The NC highway shield first appeared in 1921 with an interlocking NC, but as discussed earlier, with a slightly different N. At most, the interlocking NC within the highway shield was "inspired" by UNC's logo.

By the 2000s, it was rare to find any interlocking NC signs standing.  This one near Troutman was one of the last standing. (Chris Patriarca, 2003)

The University of North Carolina trademarked the interlocking NC in 1982. (5) By then, the use of the interlocking NC on highway shields had long ended.  It has been suggested within the roadgeek community that it would be nice for North Carolina to bring back the interlocking NC in its highway shield - I am not sure if that will ever happen.

The Dummy Lights of New York

  A relic of the early days of motoring, dummy lights were traffic lights  that  were  placed  in the middle of a street intersection. In those early days, traffic shuffled through busy intersections with the help of a police officer who stood on top of a pedestal. As technology improved and electric traffic signals became commonplace, they were also  originally  positioned on a platform at the center of the intersection. Those traffic signals became known as  " dummy lights "  and were common until  traffic lights were moved  onto wires and poles that crossed above the intersection.  In New York State, only a handful of these dummy lights exist. The dummy lights  are found  in the Hudson Valley towns of Beacon and Croton-on-Hudson, plus there is an ongoing tug of war in Canajoharie in the Mohawk Valley, where their dummy light has been knocked down and replaced a few times. The dummy light in Canajoharie is currently out of commission, but popular demand has caused the dummy

Colorado Road (Fresno County)

Colorado Road is a rural highway located in San Joaquin Valley of western Fresno County.  Colorado Road services the city of San Joaquin in addition the unincorporated communities of Helm and Tranquility.  Colorado Road was constructed between 1910 and 1912 as a frontage road of the Hanford & Summit Lake Railway.  The roadway begins at California State Route 145 near Helm and terminates to the west at James Road in Tranquility.   Part 1; the history of Colorado Road Colorado Road was constructed as frontage road connecting the sidings of the Hanford & Summit Lake Railway.  The Hanford & Summit Lake Railway spanned from South Pacific Railroad West Side Line at Ingle junction southeast to the Coalinga Branch at Armona.  The Hanford & Summit Lake Railway broke ground during August 1910 and was complete by April 1912. The Hanford & Summit Lake Railway established numerous new sidings.  From Ingle the sidings of the line were Tranquility, Graham, San Joaquin, Caldwell, H

Madera County Road 400 and the 1882-1886 Yosemite Stage Road

Madera County Road 400 is an approximately twenty-four-mile roadway following the course of the Fresno River in the Sierra Nevada Mountains.  Road 400 begins at California State Route 145 near Madera and terminates to the north at Road 415 near Coarsegold.  Traditionally Road 400 was known as "River Road" prior to Madera County dropping naming conventions on county highways.  Road 400 was part of the original Yosemite Stage Route by the Washburn Brothers which began in 1882.  The Yosemite Stage Route would be realigned to the west in 1886 along what is now Road 600 to a rail terminus in Raymond.  Parts of Road 400 were realigned in 1974 to make way for the Hensley Lake Reservoir.  Part 1; the history of Madera County Road 400 Road 400 is historically tied to the Wawona Road and Hotel.  The Wawona Hotel is located near the Mariposa Grove in the modern southern extent of Yosemite National Park.   The origins of the Wawona Road are tied to the Wawona Hotel but it does predate th
