U.S. Highway 45
United States Highway 45 is a north-south United States highway. As the "5" in its route number suggests, US 45 is a border-to-border route, from Lake Superior to the Gulf of Mexico. A sign at the highway's northern terminus notes the total distance as 1,300 miles (2,092 km).
US 45 is the primary route through the real-life Metropolis, Illinois, a town of about 6,000 population that calls itself "Superman's Hometown" in reference to the fictional comic book town of Metropolis.
