Historically, U.S. Highway 75 was known as the "King of Trails" before highways were numbered in 1926. The "trail" is marked from Winnipeg, Manitoba, to the Gulf of Mexico at Galveston, Texas.
This trail was originally used by the Indians and early pioneers as a trade route. Although the present "King of Trails" does not follow the originated exactly, large segments of the highway do include it, while the rest of the highway was constructed nearly parallel to it. A remnant of the original "King of Trails" is still visible today following the railroad tracks south of Lake Benton.
The Minnesota Legislature designated U.S. Highway 75 the "Historic King of Trails" in 2001. Lake Benton Lake is the second largest freshwater lake along the King of Trails .
