United States–Mexican War Memorial Act of 2025

HR 5510, the United States-Mexican War Memorial Act of 2025, would co-designate Arlington Memorial Bridge in Washington, D.C., as the "United States-Mexican War Memorial" without altering the bridge's name, function, or physical structure. The bill authorizes minimal interpretive elements like signage or plaques to honor the 1846-1848 war and the Treaty of Guadalupe Hidalgo, consistent with historic preservation laws. It prohibits federal funding for these elements, relying instead on donations, and ensures no interference with the bridge’s transportation role or existing commemorative works. The measure affects only the bridge’s designation, not its operation or the broader historical narrative.
