U.S. Route 16 Highway Sign - Historic National Roadway Marker #191869 (License: Personal Use)

This image shows the official U.S. Route 16 shield, featuring bold black numerals “16” centered on a white, vertically elongated octagonal (shield-shaped) background-standard for U.S. Numbered Highways. Though decommissioned in most states by the 1970s, Route 16 once connected Michigan to Wyoming and played a key role in pre-Interstate travel infrastructure. Its design follows the standardized MUTCD specifications used across the national highway network.
