Produced by MDOT and widely distributed free of charge through Travel Michigan Welcome Centers and MDOT offices, the new edition includes several upgrades: road sign symbols for M-routes and county roads now duplicate the signs used on the highway; exit numbers are listed for US-127 and M-10; information is included on roundabouts; new bridges rates, including Web addresses and phone numbers; and the state's three National Scenic Byways are identified.
