ENR Highlights Wild Horse Pass Corridor Program

A recent article in Engineering News-Record explores the complexity behind the Arizona Department of Transportation’s nearly $1 billion Wild Horse Pass Corridor program, a 26-mile improvement effort currently underway along I-10 between Phoenix and Casa Grande. The article details how the program will add capacity, modernize interchanges, expand HOV lanes and incorporate intelligent transportation systems while improving safety and mobility on one of the Southwest’s most important commuter and freight corridors.

The story highlights HDR’s role as program manager and general engineering consultant for the initiative. In the piece, Miloš Vasiljević, HDR transportation program management director, discusses the extensive coordination required among the Gila River Indian Community, state and federal agencies and local stakeholders to deliver improvements across sovereign tribal land while respecting cultural resources and community priorities.

ENR also examines the program’s phased delivery strategy, innovative construction approaches and efforts to maintain traffic on a corridor that offers few detour options. The article notes that most of the work is scheduled for completion in 2029 and showcases how collaboration among stakeholders is helping advance a more resilient and efficient transportation corridor for Arizona communities.
