Federal Forest Highway 16 (FFH 16) is a forest highway in the western Upper Peninsula of the US state of Michigan that runs through the Ottawa National Forest in Iron, Houghton and Ontonagon counties. The Michigan Department of Transportation (MDOT) has erroneously marked it as H-16 on their official state map. FFH 16 is designated by the US Forest Service (USFS) with maintenance shared by the county road commissions (ICRC, HCRC, OCRC, respectively). Although the MDOT maps would suggest that it is a part of the County-Designated Highway System (CDH system), it is not. The three counties in question do not participate in the system, and the roadway falls in the middle of the G zone for numbering purposes.
