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.

California State Route 232

This past month I drove the entirety of California State Route 232 in Ventura County. CA 232 is an approximately 4 miles State Highway aligned on Vineland Avenye which begins near Saticoy at CA 118 and traverses southwest to US Route 101 in Oxnard.  The alignment of CA 232 was first adopted into the State Highway System in 1933 as Legislative Route Number 154 according to CAhighways.org. CAhighways.org on LRN 154 As originally defined LRN 154 was aligned from LRN 9 (future CA 118) southwest to LRN 2/US 101 in El Rio.  This configuration of LRN 154 between CA 118/LRN 9 and US 101/LRN 2 can be seen on the 1935 California Division of Highways Map of Ventura County. 1935 Ventura County Highway Map According to CAhighways.org the route of LRN 154 was extended west from US 101/LRN 2 to US 101A/LRN 60 in 1951.  Unfortunately State Highway Maps do not show this extension due to it being extremely small. During the 1964 State Highway Renumbering LRN 154 was assigned CA 232.  Of n

One Long Drive - Allegheny County's Orange Belt

When I trace my early interest in traveling and the hobby of roadgeeking, I always go back to where I grew up. Pittsburgh, Allegheny County, PA 48, and the Orange Belt. I grew up on Route 48 in Elizabeth Township on the Orange Belt. One of my family's favorite stories of me growing up is when I was around three years old - so 1980 - I told one of my aunts, "It's not that hard to get to our house - we live on the Orange Belt!"  The Allegheny County Belt System is one of the many things that are uniquely Pittsburgh. A series of existing roadways - minor and major - developed in post-World War II Allegheny County to navigate the region. Never intended to be a "beltway" in the modern sense - a full freeway encircling a city - the Allegheny County system is more like a wayfinding system connecting you throughout the county. It is uniquely Pittsburgh - it's been asked about , written about , and videoed .  On a recent visit home, I decided to drive the entire

Mosquito Road Bridge

The Mosquito Road Bridge is a wooden suspension span crossing the South Fork American River of El Dorado County.  The Mosquito Road Bridge incorporates elements in it's foundation which date back to 1867 making it likely the oldest highway bridge in California still is in service for it's original purpose.  The Mosquito Road Bridge can be found approximately 6.5 miles northeast of downtown Placerville.    Author's Note; Gribblenation's 2,000th published blog This blog serves as the 2,000th published entry on the Gribblenation blog site.  Ironically the the 2,000th blog entry closely aligns with the 20th anniversary of Gribblenation.  Adam and Doug recently discussed the history of Gribblenation on the Gribblenation 20th Anniversary Podcast: https://anchor.fm/gribblenation/episodes/Gribblenation-20th-Anniversary-Podcast-ep2nh8 For my own part I (Tom) have been part of Gribblenation since late 2016, it has been an honor to be part of one of the longest lived highway pages
