What’s America’s longest Main Sreet?

Island Park is a small city in Fremont County, Idaho, known for its stunning natural beauty and outdoor recreational opportunities. The city lines were drawn around existing lodges along the old Highway 20, giving it an unusual configuration. But what sets Island Park apart is its claim to fame as having the "Longest Main Street in America."

Main Street, also known as U.S. Highway 20, runs for 33 miles from Last Chance to Valley View within the city limits.

Colfax Avenue in Denver, Colorado, is often regarded as the longest street in the United States. This street stretches for approximately 50 miles from west to east, traversing Denver and its suburbs.
