The Bipartisan Infrastructure Law continued the Recreational Trails Program (RTP) as a set-aside from the Transportation Alternatives program. The RTP provides funds to states to develop and maintain recreational trails and trail-related facilities for both nonmotorized and motorized recreational trail uses. The funds represent a portion of the motor fuel excise tax collected from nonhighway recreational fuel use by snowmobiles, all-terrain vehicles, off-highway motorcycles, and off-highway light trucks.
