Arizona State Route 95S along former AZ 172 to Parker Dam

Back in 2012 I drove the entirety of the 0.8 Mile Arizona State Route 95S located in northern La Paz County, Arizona along the Colorado River at Parker Dam.






Parker Dam is a concrete arch gravity dam which impounds the Colorado River to create Lake Havasu.  Parker Dam has an unusual design in that the structure is 320 feet tall but 235 feet of is is located below the bed of the Colorado River which apparently makes it the deepest dam in the world.  Park Dam was part of the 1922 Colorado River Project and work began 1934.  At the time the State of Arizona actually had not signed off on the plans to build Parker Dam due to unease over the water share.  The governor actually sent Arizona National Guard to halt construction by the Department of the Interior on the Arizona side of the Colorado River in 1935.  Arizona won it's case against the Department of the Interior in the Supreme Court but ultimately signed off on the project after being improvements to water reclamation on the Gila River.  Parker Dam was subsequently completed in 1938 which created a new roadway between Arizona and California.

The 1938 Arizona State Highway Map shows the completed Parker Dam north of Parker and AZ 72.

By 1958 Arizona State Route 172 was designated as a new State Highway between AZ 72 in Parker to the California State Line over Parker Dam.  AZ 172 can be seen on the below 1961 Arizona State Highway Map.

At some point in 1962 AZ 172 was designated as an extension of AZ 95 which eventually was signed north to US 66/I-40 with an additional segment north to AZ 68.  This action created not only a spur route of AZ 95 at Parker Dam but another in Parker connecting to CA 62 at the Colorado River which is also 0.80 miles.  Both AZ 95S routes are the shortest State Maintained Highways in Arizona with AZ 24 being the next shortest at 1.4 miles.  Arizonaroads.com has various pictures showing the odd signage of the AZ 95S routes.

Did Caltrans just kill the G26 cutout US Route shields?

The US Route System was formally created by the American Association of State Highway Officials during November 1926.  Through the history of the system the only state to which has elected to maintain cutout US Route shields has been California.  The G26 series cutout US Route shields have become a favorite in the road enthusiast hobby and are generally considered to be much more visually pleasing than the standard Federal Highway Administration variant.  However, the G26 shield series appears to have been killed off on January 18, 2026, when Caltrans updated their Manual of Uniform Traffic Control Devices.  This blog will examine the history of the US Route shield specifications in California and what is happening with the 2026 changes.  The blog cover photo is facing towards the terminus of California State Route 136 and at a G26-2 specification US Route 395 shield.  In the background Mount Whitney can be seen in the Sierra Nevada range.   ...

May 2023 Ontario Trip (Part 3 of 3)

  Over the years, I have made plenty of trips to Ontario, crisscrossing the southern, central and eastern parts of the province. Living in Upstate New York, it's pretty easy to visit our neighbor to the north, or is that our neighbor to the west? Ottawa is one of my favorite cities to visit anywhere in the world, plus I've discovered the charm of Kingston, the waterfalls of Hamilton (which is on the same Niagara Escarpment that brings us Niagara Falls), the sheer beauty of the Bruce Peninsula, and more. But I hadn't explored much of Cottage Country. So I decided to change that, and what better time to go than over Memorial Day weekend, when the daylight is long and I have an extra day to explore. On the third and final day of my trip, I started in Huntsville and made my way through Muskoka District and Haliburton County, passing by many lakes along the way. I stopped in towns such as Dorset, Haliburton and Bancroft before making a beeline down to Belleville and then over th...

Ghost Town Tuesday; Nichols, FL

A couple years ago I spent a lot of spare time exploring phosphate mining ghost towns in the Bone Valley of Polk County, Florida.  One ghost town in particular called Nichols on Polk County Route 676 west of Mulberry caught my eye due to a relative lack of documentation on ghosttowns.com. Nichols was created in 1905 during the early phosphate mining boom in the Bone Valley region.  For the time Nichols was unusual since it had company housing in the Nichols Mine site and private residences outside the gate.  Nichols is only about two miles west of Mulberry which probably made it a somewhat reasonable commute even by the wonky standards of the early 20th Century.  Most of the Bone Valley region was relatively remote which made commuting or homesteading impractical which is why there are so many ghost towns in the area.  The company housing section of Nichols was phased out and abandoned by 1950. The Nichols town site is largely abandoned and could "possibl...
