Arizona State Route 24


Arizona State Route 24 is a partially completed freeway in southeastern Maricopa County.  As presently constructed Arizona State Route 24 begins at Arizona State Route 202 near Phoenix-Mesa Gateway Airport and terminates 5.48 miles to the east at Ironwood Drive.  Arizona State Route 24 is known as the Gateway Freeway and is planned to eventually continue into Pinal County.  The first mile of Arizona State Route 24 between Arizona State Route 202 and Ellsworth Road opened to traffic on May 4, 2014.  The interim Phase II extension of Arizona State Route 24 east to Ironwood Drive opened to traffic on August 11, 2022.  




Part 1; the history of Arizona State Route 24

The origin of Arizona State Route 24 dates to September 2003 when a Final Report on the Southeast Maricopa/Northern Pinal County Transportation Study was released.  The Final Report was prepared by the Maricopa Association of Governments, Central Arizona Association of Governments and Arizona Department of Transportation.  The Final Report identified the future corridor Arizona State Route 24 as being necessary due to the outward suburban sprawl of eastern Maricopa County into Pinal County.  






During March 2006 the Maricopa Association of Governments released a Final Report regarding the preferred corridor of what was then numbered as Arizona State Route 802.  The final report identified the preferred corridor of Arizona State Route 802 as beginning near Phoenix-Gateway Gateway Airport traveling southeast.  The preferred corridor of Arizona State Route 802 turned east at Frye Road towards the Pinal County line.  

During 2009 the Maricopa Association of Governments altered Regional Transportation Plan due to the ongoing recession.  Maricopa County funding of Arizona State Route 802 was subsequently pulled back to 2026 or later between Ellsworth Road and Meridian Road.  An interim freeway between Arizona State Route 202 (the San Tan Freeway) and Ellsworth Road was to be constructed during the 2016-2020 timeframe. 

During 2011 the city of Mesa fronted $148 million to funding construction of the first mile of the new freeway between Arizona State Route 202 and Ellsworth Road.  The so-called "Gateway Freeway" was announced as being renumbered as Arizona State Route 24 by AZcentral on June 6, 2011.  The first mile of Arizona State Route 24 from Arizona State Route 202 to Ellsworth Road opened to traffic on May 4, 2014. 

The interim eastern extension of Arizona State Route 24 from Ellsworth Road to Ironwood Road fully opened to traffic on August 11, 2022.  The interim Phase II extension included two general purpose lanes in each travel direction but not the interchanges east of Ellsworth Road.  The interim Phase II alignment of Arizona State Route 24 utilizes what will be the on/off ramps at Williams Field Road, Signal Butte Road, Moeur Road and Ironwood Road. 

The nearly complete interim Phase II alignment of Arizona State Route 24 was featured by the Arizona Department of Transportation on August 1, 2022.  




To date no preferred corridor for an extension of Arizona State Route 24 has been selected in Pinal County.  The study to determine a routing in Pinal County has been suspended to allow for it to advance in conjunction with the with the Pinal North-South Freeway.  Planning maps from a December 2009 Arizona Department of Transportation Environmental Assessment depict the general corridor of the Gateway Freeway continuing east to Florence Junction near the intersection of US Route 60 and Arizona State Route 79.

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
