概要
The National Park Service proposes to designate the Sleeping Bear Heritage Trail currently under construction within Sleeping Bear Dunes National Lakeshore as a route for bicycle use. The approximately 27-mile-long trail will generally parallel major state highways and offer visitors safe, non-motorized access to the park. National Park Service general regulations require promulgation of a special regulation to designate routes for bicycle use outside developed areas or off park roads.
