Bridge Monday; the Roosevelt Lake Bridge and Roosevelt Dam

Back in the early 2010s I frequently visited Gila County Arizona.  Often my travel took me up Arizona State Route 88 (usually for fun) and Arizona State Route 188.  The junction of AZ 88 and AZ 188 holds what was two significant bridging structures of Roosevelt Lake; the Roosevelt Dam and Roosevelt Lake Arch Bridge.


AZ 88 is one of the oldest State Highways in Arizona dating back to 1927.  While the highway was originally intended to be signed as AZ 66 the designation of AZ 88 was ultimately chosen due to US 66 being assigned over what was intended to be US 60 in Arizona.  As originally signed AZ 88 stretched from US Route 80 in Apache Junction east to the first US 180 in Globe.  By 1927 Roosevelt Dam was long completed since 1911 as it was the signature structure of the Salt River Project.  Roosevelt Dam was used as a bridging structure from AZ 88 north to the road to Payson.  This 1927 highway map of Arizona shows the location of Roosevelt Dam on the initial alignment of AZ 88.


Construction of Roosevelt Dam began along the Salt River in Gila County by 1903, as stated above the structure was completed by 1911.  Roosevelt Dam and the Salt River Project were part of the 1902 Reclamation Act which paved the way for later more well known public works projects such as the Hoover Dam.  Roosevelt Dam as originally completed was a completely masonry dam and was the largest of it's type at the time.  


According to Arizonaroads.com the route of AZ 188 from AZ 88 at Roosevelt Dam north to Payson was designated in 1958.  At the time the junction of AZ 88 and AZ 188 was at Roosevelt Dam.   AZ 188 can be viewed in it's originally configuration crossing Roosevelt Dam on the 1961 State Highway Map.



In 1989 an expansion project to raise Roosevelt Dam from 280 feet to 357 began.  Said project was to expand Roosevelt Dam via use of a new masonry cover over the original dam structure.  The Roosevelt Dam expansion project required AZ 188 be shifted onto a new bridge over Roosevelt Lake.  The new Roosevelt Lake Arch bridge was completed by 1992 and remains one of the more scenic bridges in Arizona. 


According to Arizonaroads.com AZ 188 was shifted over what was AZ 88 east of Roosevelt Dam to Globe by 2000.  The change was apparently instigated due to a new ADOT policy about having a highway have both terminus points at the same route.

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...
