Blue Highway (tourist route)

A Blue Highway, in the context of United States travel, refers to back roads and lesser-known routes, particularly those depicted in blue on older road maps (specifically Rand McNally road maps). The term gained popularity following the publication of William Least Heat-Moon's 1982 travelogue, Blue Highways: A Journey into the Heart of America, which documented his journey across the United States using these smaller, less-traveled roads.

Blue Highways typically offer a more scenic and authentic travel experience compared to interstate highways and major thoroughfares. They often wind through rural landscapes, small towns, and areas rich in local history and culture. Travelers who choose Blue Highways often seek a slower pace, a connection with local communities, and opportunities to discover hidden gems and unique regional experiences.

The appeal of traveling Blue Highways lies in the contrast they offer to the homogenization and speed of interstate travel. While interstates prioritize efficiency and direct routes, Blue Highways emphasize exploration, serendipity, and a deeper understanding of the American landscape and its people. The routes often lead to historic sites, natural wonders, and locally owned businesses that are bypassed by those traveling on main highways. The term "Blue Highway" has become synonymous with this type of slow travel and the pursuit of authentic American experiences.
