H.R. No. 1478 is a resolution commemorating the upcoming centennial of Route 66, which was established in 1926 as part of the first federal highway system in the United States. The resolution highlights the historical significance of Route 66, noting its role in promoting tourism, economic growth, and community development across its 2,400-mile stretch from Chicago to Los Angeles. It acknowledges the highway's impact during various historical periods, including the Great Depression and World War II, and its eventual decline with the rise of the interstate system. Despite its decommissioning in 1985, Route 66 remains a cherished symbol of American culture and history, with ongoing preservation efforts by local organizations.

The resolution expresses the Texas House of Representatives' support for the centennial celebrations and preservation initiatives related to Route 66, particularly in Texas, where over 150 miles of the original route are still accessible. It recognizes the contributions of the Old Route 66 Association of Texas and other stakeholders in promoting tourism and restoring historical landmarks. The resolution concludes with a commitment to honor the legacy of Route 66 and extend best wishes to those involved in the centennial celebrations and preservation efforts.
