U.S. Route 40 Marker

Identifies the roadway as U.S. Route 40, part of the U.S. Numbered Highway System.

The familiar black-and-white shield marks a route in the U.S. Numbered Highway System maintained cooperatively by the states. Use it for navigation across state lines, since U.S. route numbers stay consistent regardless of which state you are in.
