MAP-21 consolidated several transportation programs including Transportation Enhancements, Safe Routes to School, and Recreational Trails into the new Transportation Alternatives program. It reduced funding for biking and walking projects and made changes to project eligibility and how funding is distributed between population-based and competitive grant programs. It also expanded eligibility and opportunities for biking and walking projects to receive funding under programs like HSIP, CMAQ, STP, and Federal Lands transportation.
