The Federal Transit Administration awarded Northern Arizona Intergovernmental Public Transportation Authority (NAIPTA), operating as Mountain Line, a Formula Grant of $9.57 million under the Federal Transit Formula Grants program (CFDA 20.507) on August 27, 2025. This capital award funds two primary infrastructure projects at the Mountain Line Downtown Connection Center (DCC) facility in Flagstaff, Arizona: construction of rooftop solar electricity generation infrastructure and development of a bus transfer center plaza. The solar installation is expected to reduce operational utility costs through on-site electricity generation, while the bus transfer center plaza will enhance operational efficiency, improve transit rider transfer processes, and reduce congestion at the facility.

NAIPTA intends to execute both projects without subrecipient involvement and anticipates completion by December 31, 2027. The award directly benefits the NAIPTA service area population and transit riders throughout northern Arizona by supporting critical transportation infrastructure improvements that align with the Federal Transit Formula Grants program's objective to develop and improve transit systems in urbanized areas. These capital improvements demonstrate NAIPTA's commitment to enhancing public transportation services while addressing operational sustainability and rider experience priorities.
