To designate United States Route 20 in the States of Oregon, Idaho, Montana, Wyoming, Nebraska, Iowa, Illinois, Indiana, Ohio, Pennsylvania, New York, and Massachusetts as the "National Medal of Honor Highway", and for other purposes.

This bill renames U.S. Route 20 across 12 states (Oregon, Idaho, Montana, Wyoming, Nebraska, Iowa, Illinois, Indiana, Ohio, Pennsylvania, New York, and Massachusetts) as the "National Medal of Honor Highway." It directly affects the highway itself and all official U.S. government references to it, such as maps and documents. The key provision requires that any federal law, record, or document mentioning this highway must now use its new name to honor Medal of Honor recipients' service and valor. The bill makes no changes to highway operations, funding, or policy - only to the official designation.
