    The Lolo Motorway follows a trail network that has thousands of years of history deeply embedded in it. The Nez Perce Tribe, the Lewis and Clark Expedition, pioneers, prospectors, the Civilian Conservation Corps, and U.S. Forest Service, all have a long and deep historic connection with the corridor in which the Lolo Motorway resides.

    For decades this route has been referred to as the “Lolo Trail,” and has been classified as a National Historic Landmark in the National Register of Historic Places. It is a major component of the Nez Perce National Historic Park.

    The Lewis and Clark Expedition struggled along these same ridge-lines on their journey west in 1805, and on their return trip in 1806. The segment of trail the Motorway follows is the longest intact segment of the Lewis and Clark National Historic Trail.

    In 1877, during the Nez Perce War, the non-treaty Nez Perce people followed the route in their flight from General Oliver O. Howard and the U.S. Army. In 1986, the Lolo Motorway and the rest of the route they traveled became part of the Nez Perce (Nee-Me-Poo) National Historic Trail.

    The Lolo Motorway was constructed along these historic trails in the 1930s by the U.S. Forest Service and Civilian Conservation Corps. Although narrow, rocky, and slow-going, the route provided access into the mountains, furthering development of natural resources in the Clearwater region.

    While the Lolo Motorway is a spectacular drive, make sure you are prepared before heading out. This primitive, un-maintained, one-lane road is suitable for high-clearance vehicles, pickup trucks, motorcycles, and mountain bikes. Pulling a trailer along this road is not recommended, as there are few turnouts, many hairpin turns, and protruding rocks.
