In 2024, the New Mexico Department of Transportation (NMDOT) completed the I-40 Phase 1-A/B Corridor Study (CN 6101580), which examined the stretch of Interstate 40 between the Arizona state line and Albuquerque. The goal of that study was to create a long-term plan to improve traffic flow and reliability, enhance safety, and maintain the overall condition of I-40 and its supporting infrastructure.

Recommended improvements from the I-40 Phase 1-A/B Corridor Study included:

• Maintaining two travel lanes in each direction
• Widening inside and outside shoulders
• Adding a 26-foot flush median with a concrete barrier wall
• Adding auxiliary lanes and extending entrance and exit ramps
• Addressing bridge, pavement, and drainage needs

The I-40 Miyamura Interchange and surrounding streets in Gallup currently experience traffic and safety challenges. This focused Phase 1-A/B study will take a closer look at the Miyamura Interchange and nearby intersections to evaluate how the interchange functions today, identify potential improvements, and incorporate recommendations from the larger I-40 Corridor Study.

Funding for the study and design phases comes from a combination of state and federal sources. State funding was provided through House Bill 2 from the 2022 Legislative Session, while federal funding comes from the Road Fund and the Surface Transportation Program (FLEX_NC).

The construction phase will be supported with federal funds through the National Highway Performance Program and the Federal Road Fund.
