As you travel north on US-41 into Keweenaw County, you will see why this stretch has been designated a state Scenic Heritage Route. It is the northernmost section of US-41, which stretches the length of the nation, from Florida to Copper Harbor. The highway winds its way through smaller mining-era communities until it enters the woods, where trees form a living canopy over the roadway. The last 11 miles leading to Copper Harbor is known locally as the "tree tunnel" and offers beautiful views of the northern forest.

From MDOT: "The first road designated as a Scenic Heritage Route was the eighteen-mile segment of US-41 from Central to Copper Harbor in Keweenaw County in the Upper Peninsula. The uniqueness of this road is its forest and how the trees, some as close as three feet from the edge of the pavement, form a complete canopy over most of the entire length of the Heritage Route. This road provides access to such recreational resources as Lake Superior beaches, Copper Harbor, Historic Fort Wilkins state park, hunting, fishing, and fall color touring."

The first 18 miles of the route were designated as a Scenic Heritage Route in 1994 from Central to Copper Harbor, then extended southwesterly to Mohawk in 2002 and then to Houghton in the spring of 2004.

US-41 has proved itself unique and scenic with historical interest. It has been listed as a National Scenic Byway. This part of of US-41 is called the Copper Country Trail.

From NSB: The National Scenic Byways Program is part of the U.S. Department of Transportation, Federal Highway Administration. The program is a grass-roots collaborative effort established to help recognize, preserve and enhance selected roads throughout the United States.
