This letter and accompanying map promote the use and expansion of the International Meridian Highway that began in Winnipeg, Canada, and ended in Mexico City, Mexico. The road follows the 6th Principal Meridian through the Great Plains area of the United States and is officially called U.S. Highway 81. The letter and map provide an update on road construction and indicate which sections of the road were paved, gravel, or earth. The letter argues that this highway should be designated the official segment of the Pan American Highway through the United States, and that the highway should be extended all the way to Argentina in South America. John C. Nicholson was president of the Meridian Highway Association with offices in Newton, Kansas.
