Welcome  Our Mission Statement The mission of the Commission is to enhance the social and economic quality of life of our community by providing and maintaining, consistent with financial resources available to the Commission, a safe and efficient system of county roads and streets for the citizens of Manistee County and to continuously strive to improve the quality of the service we deliver.     US 31 between Manistee and Mason Counties is now open! Please use extreme caution when traveling Manistee County and Mason County roads due to severe weather received the evening of June 12th. Many roads in the area have been washed out or are currently under water.  Road crews are working feverishly to repair these areas. DRIVE CAREFULLY AND HAVE A GREAT SUMMER!
