CALEDONIA, Mich. - In partnership with Caledonia Township and the Kent County Road Commission, the Michigan Department of Transportation (MDOT) is rebuilding 3 miles of M-37 (Broadmoor Avenue) in Caledonia Township and the village of Caledonia. The project involves extending the existing boulevard that ends north of 76th Street to 92nd Street to address operational and safety needs in this growing area. Improvements include:

• Widening the roadway to a four-lane boulevard with indirect left-turns (Michigan Lefts).
• Installing new traffic signals with intersection improvements at 92nd, 84th and 76th streets, as well as a new traffic signal and improvements at the 84th Street/Cherry Valley Avenue intersection.
