The NMDOT is planning transportation improvements to the I-25 Gibson Boulevard interchange and to I-25 between Sunport Boulevard and Avenida Cesar Chaves. The purpose and need of the project were identified in previous studies. The need for action was based on existing operational and geometric deficiencies on I-25 mainline segments and at interchanges. Improvements to the South I-25 corridor are needed to maintain and/or enhance performance and safety, accommodate future increases in travel demand, address multimodal accommodations, and support economic development in the corridor.
