The purpose of this legislation, known as the Modernizing Access to Public Roads Act, is to enhance the management and accessibility of county roads across the United States. It aims to achieve this by establishing a grant program that supports the digitization of county road information and the creation of publicly accessible road datasets. The overall goal is to improve rural commerce, public safety, and navigation for all users. Key provisions of the act include the establishment of a pilot program by the Secretary of Transportation within 180 days of the law's enactment.
