The Rails-to-Trails program emerged from a convergence of environmental, recreational, and transportation concerns in the late 20th century United States. Beginning in the 1960s and gaining momentum in the 1970s and 1980s, the program sought to repurpose abandoned railway corridors into multi-use trails for walking, cycling, and other recreational activities. The initiative was born out of a recognition of the potential of these disused railways to serve as valuable public assets, providing safe and accessible routes for non-motorized transportation while preserving open space and connecting communities. Through grassroots activism, advocacy by environmental and outdoor recreation organizations, and government support at various levels, the Rails-to-Trails movement gained traction, leading to the establishment of thousands of miles of trails across the country. Today, these trails not only offer opportunities for exercise and enjoyment of nature but also contribute to economic development and tourism in the regions they traverse.
