This study found that the North Central Rail Trail is used heavily by residents who lack safe walking and cycling alternatives on local roadways; trail use grew 42 percent per year during the first decade it was open. Both residents and nearby property owners overwhelmingly found the trail a good investment of public funds and would support state-funded trails built elsewhere in the state.
