Tri-County Trivia

(Fun facts about the Greater Lansing Michigan region of Clinton, Eaton and Ingham Counties)
Converting a 4 lane road into 3, usually with a center turn lane and two sides of bike lane; is called a "road diet" and can be safe and healthy. Mid-Michigan's tri-county region is a national leader in road diets with 15 miles converted and 18 miles more planned for conversion by 2016.
