The "Modernizing Access to Public Roads Act" (MAP Roads Act) directs the Secretary of Transportation to establish a pilot grant program within 180 days of enactment. This program will provide grants to States to fund the digitization of county roads and the creation of centralized, publicly accessible road datasets . The primary goals are to support rural commerce, increase public safety, and improve public access and navigation across the country. To receive a grant, States must demonstrate a significant deficiency in digitized county roads, the capacity to administer subgrant programs to counties, and a commitment to coordinating shared geospatial data standards. Funds distributed to counties can be used to digitize official records, convert outdated formats to standardized geospatial datasets, and train personnel. Participating State departments of transportation must serve as central data repositories, ensuring the data is published on a publicly accessible website, distinguishes between public and private roads, is compatible with third-party mapping platforms, and is updated at least annually. The bill authorizes an appropriation of $20,000,000 annually for fiscal years 2026 through 2031 to carry out this program.
