U.S. Route 71 in Louisiana

U.S. Route 71 is a major north-south United States highway than runs from US 190 near Krotz Springs, Louisiana to Fort Frances–International Falls International Bridge in International Falls, Minnesota at the Canada–United States border. In the U.S. state of Louisiana, US 71 begins at an interchange with US 190 west of Krotz Springs, then travels in a mostly northwestern direction to the Arkansas state line just north of Ida, serving the major cities of Alexandria, Bossier City, and Shreveport.

With the advent of the Interstate Highway System, US 71 in Louisiana has been largely superseded by I-49, with most of US 71 running parallel to I-49. US 71 intersects I-49 three times in Louisiana: twice in Alexandria and once near Hosston. Additionally, US 71 briefly overlaps I-20 through Bossier City and Shreveport. The section of US 71 from LA 170 in Gilliam to LA 2 east in Hosston forms part of the Boom or Bust Byway, a Louisiana Scenic Byway.
