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. The resolution highlights the historical significance of Route 66, noting its role in promoting commerce and tourism, particularly during the Great Depression and post-World War II era. Despite its decommissioning in 1985 due to the rise of the interstate system, Route 66 remains an important cultural and economic artery, with efforts from organizations like the Old Route 66 Association of Texas to preserve its legacy and promote tourism along its historic route.

The Texas House of Representatives expresses its best wishes to those involved in the preservation and celebration of Route 66, recognizing its impact on communities and American culture. The resolution also calls for an official copy to be prepared for the Old Route 66 Association of Texas as a gesture of appreciation from the Texas Legislature.
