routing of FFH-16. The roadway is part of the Forest Highway System that is funded and administered by the US Forest Service and the Federal Highway Administration; the system was created by the Federal Aid Highway Act of 1921. The highway has never been included in the CDH system as Iron, Houghton and Ontonagon counties do not participate in the system, and the Upper Peninsula east of US 41 is the G zone, not the H zone.
