In 1939, the Texas Highway Department renumbered all highways that ran concurrently with U.S. Highways. Sections of state highways that were separated by a concurrency with a US Highway were renumbered, and all suffixed routes (that did not become part of other highways or other state highways) were renumbered.
Routes not in the above table; if nothing is stated no changes were made
