US Route 191Y

US Roure 191Y is a hidden State Highway designation on Page Ranch Road in Cochise County, Arizona.  US Route 191Y is a 3.5-mile spur of US Route 191 which originates at Interstate 10 Exit 355 and terminates to the northwest via Page Ranch Road at mainline US Route 191.  US Route 191Y is not a signed highway but nonetheless has Arizona Department of Transportation mile markers reflecting mileage from mainline US Route 191.  Page Ranch Road was added to the Arizona State Highway system as US Route 666Y during 1958.  During 1992 US Route 191 was extended south to the Mexican border which led to Page Ranch Road being reassigned as US Route 191Y. 

Part 1; the history of US Route 191Y

What is now US Route 191Y and Page Ranch Road was added to the Arizona State Highway System during September 9, 1927, as Arizona State Route 81.  Arizona State Route 81 originated at US Route 80 near Douglas and terminated at the US Route 180 in Safford.  Arizona State Route 81 can be seen aligned past Bowie Junction and modern Page Ranch Road on the 1927 Arizona State Highway Commission Map.  

Arizona State Route 81 was one of the original Arizona State Routes to be defined.  

During the December 8, 1938, American Association of State Highway Officials (AASHO) meeting the Executive Commitee approved an Arizona Highway Commission request to extend US Route 666 to US Route 80.  The extension of US Route 666 subsumed the entirety of Arizona State Route 81.  

US Route 666 appears co-assigned with Arizona State Route 81 on the corridor of Page Ranch Road towards Bowie Junction on the 1939 Rand McNally Map of Arizona.  

One of the earliest highway maps to display Page Ranch Road split from US Route 666 is the 1948 Rand McNally Map of Arizona.  Page Ranch Road is displayed as a locally maintained roadway connecting from Arizona State Route 86 at Bowie Junction northwest to US Route 666.  

US Route 666Y was created via a right-of-way resolution dated January 24, 1958

According to the 2013 Arizona Department of Transportation mileage log, Page Ranch Road was built to state standards during 1961.  The mileage log notes Page Ranch Road to currently be part of US Route 191Y.  The US Route 191Y designation for Page Ranch Road during 1961 would have been US Route 666Y.  State maintenance of Page Ranch Road is noted to have been 3.11 miles during 1961.  

The first half mile of US Route 666Y appears to have been realigned at some point during the 1960s during the construction of the Luzena Interchange (Exit 355) of Interstate 10 at Bowie Junction.  The construction of Luzena Interchange extended US Route 666Y to a length of 3.5 miles.  The razed older grade of Page Ranch Road and US Route 666Y can be seen on Google satellite images.  

On May 8, 1992, the Arizona Department of Transportation submitted an application to AASHTO eliminate US Route 666 in the state.  The application came with a secondary request to extend US Route 191 from Chambers south to the Mexican border in Douglas over the existing routing of US Route 666.  Both requests were approved by the AASHTO Executive Committee on June 15, 1992.  

The extension of US Route 191 led to the redesignation US Route 666Y on Arizona Department of Transportation logbooks as US Route 191Y on September 18, 1992.  US Route 191Y is not an officially recognized US Route by AASHTO.

Horace Wilkinson Bridge (Baton Rouge, LA)

Standing tall across from downtown Baton Rouge, the Horace Wilkinson Bridge carries Interstate 10 across the lower Mississippi River between West Baton Rouge and East Baton Rouge Parishes. Unusually, the bridge is actually named for three separate people; three generations of Horace Wilkinsons who served in the Louisiana State Legislature over a combined period of 54 years. Constructed in the 1960s and opened to traffic in 1968, this is one of the largest steel bridges on the lower Mississippi. It’s also the tallest bridge across the Mississippi, with its roadway reaching 175 ft at the center span. Baton Rouge is the northernmost city on the river where deep-water, ocean-going vessels can operate. As a result, this bridge is the northernmost bridge on the river of truly gigantic proportions. Altogether, the bridge is nearly 2 ½ miles long and its massive truss superstructure is 4,550 ft long with a center main truss span of 1,235 ft. The Horace Wilkinson Bridge is one of the largest

Veterans Memorial Bridge (Gramercy, LA)

When we think of the greatest engineering achievements and the greatest bridges of North America, we tend to focus on those located in places familiar to us or those structures that serve the greatest roles in connecting the many peoples and cultures of our continent. Greatness can also be found in the places we least expect to find it and that 'greatness' can unfortunately be overlooked, due in large part to projects that are mostly inconsequential, if not wasteful, to the development and fortunes of the surrounding area. In the aftermath of the George Prince ferry disaster that claimed the lives of 78 people in October 1976 in nearby Luling, LA, the state of Louisiana began the process of gradually phasing out most of its prominent cross-river ferry services, a process that remains a work in progress today. While the Luling-Destrehan Ferry service was eliminated in 1983 upon completion of the nearby Hale Boggs Memorial Bridge, the ferry service at Gramercy, LA in rural St.

Sunshine Bridge (Donaldsonville, LA)

Located about halfway between Baton Rouge and New Orleans in southern Louisiana, the Sunshine Bridge spans the lower Mississippi River near the city of Donaldsonville as part of the longer Louisiana Highway 70 corridor, which connects Interstate 10 and Airline Highway (US 61) with US 90 in Morgan City. In the years following World War II, the only bridges across the lower Mississippi River in Louisiana were located in the area of the state’s two largest cities – Baton Rouge and New Orleans. Postwar agricultural and industrial development along the river in this region led to the planning of a series of infrastructure projects in southern Louisiana that were aimed at spurring this development and modernization of the Delta region. One of these projects was known as the Acadian Thruway and was developed in the 1950s as a toll road intended to connect greater New Orleans with Lafayette and points west while providing a high-speed bypass of the Baton Rouge metro area. The Thruway, which
