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.

Former US Route 50 and the Pioneer Route Lincoln Highway on Johnson's Pass Road

Johnson's Pass Road is one of the oldest highway corridors in California.  Johnson's Pass was part of the Lake Tahoe Wagon Road as it was completed during 1856 over the Sierra Nevada.  The pass would later be incorporated into the Pioneer Branch of the Lincoln Highway in 1913 and US Route 50 in 1926.  Johnson's Pass Road would be bypassed by a new alignment of US Route 50 over Echo Summit in 1938.  A replacement of the Meyers Grade east of Johnson's Pass would be opened to traffic in 1947.   Johnson's Pass Road remains accessible to traffic and is still signed by the Lincoln Highway Association.  Pictured as the blog cover is the view from the top of Johnson's Pass Road overlooking modern US Route 50 and Lake Tahoe.   Part 1; the history of Johnson's Pass Much of the history of what become the Lake Tahoe Wagon Road is discussed in the  September 1950 California Highways & Public Works  during its Centennial Edition.  The or...

Former US Route 50 and the South Lincoln Highway from Folsom east to Placerville

The corridor of Folsom of Sacramento County east to Placerville of El Dorado County has been a long established corridor of overland travel dating back to the California Gold Rush.  The Folsom-Placerville corridor was once part of the path of the Lake Tahoe Wagon Road which became the first California State Highway and later the South Lincoln Highway.  In time the South Lincoln Highway's surface alignment was inherited by US Route 50.  The Folsom-Placerville corridor also includes the communities of; Clarksville, Shingle Springs and El Dorado. Part 1; the history of the Lake Tahoe Wagon Road, South Lincoln Highway and US Route 50 through Folsom-Placerville Folsom is located on the American River/Lake Natoma of eastern Sacramento County.  That lands now occupied by the City of Folsom were part of Rancho Rio de los Americanos prior to the finding of gold at Sutter's Mill during 1848.  During the California Gold Rush the lands of Rancho Rio de los Americanos were p...

Old NC 10 - The Central Highway: Old Fort to Black Mountain through the Royal Gorge

A unique way of tracing the remnants of the Central Highway is through the mountainous terrain of Eastern Buncombe and Western McDowell Counties.  From the east on US 70, you reach the base of Blue Ridge Mountains at the town of Old Fort.  Old Fort is a tiny rail town that the old Central Highway and now US 70 goes through.  The Central Highway can be followed via a right onto Mill Creek Road from US 70.  Follow the highway as it takes you closer to the mountains.  When Mill Creek Road bears right to head towards Andrews Geyser stay straight until the road ends at a gate.  The nearby Piney Grove Church can be used for parking.  At this point, the old Central Highway began a 3.5 mile climb of the mountain to Swannanoa Gap.  NC 10 and later US 70 travelers followed this road for over 30 years until a new and modern four lane US 70 was built to the south.  This same four lane road would eventually become Interstate 40.    The Centra...
