Recreational Trails Grants - by State
The Recreational Trails Program (RTP) is an assistance program of the U.S. Department of Transportation's Federal Highway Administration (FHWA). The RTP provides funds to the States to develop and maintain recreational trails and trail-related facilities for motorized and nonmotorized recreational trail uses, including equestrian uses. Each state administers funds through a variety of agencies - some through their Department of Natural Resources, others through their Department of Parks and Recreation, etc. Each state's requirements for grant applications, due dates and other information is available here.
As federal programs are undergoing change, contact your state RTP office for updates to policies and information.
