Rural Opportunities to Use Transportation for Economic Success Act or the ROUTES Act This bill provides statutory authority for the Rural Opportunities to Use Transportation for Economic Success (ROUTES) Initiative at the Department of Transportation (DOT). The purpose of the initiative is to (1) improve analysis of rural projects applying for DOT discretionary grants, including ensuring that project costs, local resources, and the larger benefits to the American people and economy are appropriately considered; and (2) provide rural communities with technical assistance for meeting transportation infrastructure investment needs in a financially sustainable manner. To carry out the mission of the initiative, DOT must establish the ROUTES Council.
