The Federal Highway Administration (FHWA) provides funding for various transportation projects including pedestrian and bicycle facilities, trails, and recreational trails through programs like the Surface Transportation Program, Transportation Enhancement Activities, and Recreational Trails Program. Eligible projects include rail-trails, canal trails, riverwalks, and wildlife corridors. Funding amounts to hundreds of millions annually and is distributed through state departments of transportation. Project sponsors must follow federal requirements and work with their state to develop and fund eligible projects.
