TxDOT Memorial Highways

Memorial highways pay tribute to notable people or groups and can be designated by the state or by local government. State-designated memorial highways are designated by the Texas Legislature and typically get 2 signs that TxDOT is responsible for maintaining. Chapter 225 of the Transportation code shows the list of legislated memorial highways and is updated after each legislative session. Any local government can designate a memorial highway; however, in order to install signage on TxDOT right of way, the proposed designation must be approved by the TxDOT Commission or Executive Director. This layer reflects the designations through the 89th legislative session, which concluded in 2025. The layer will be updated again at the conclusion of the 90th legislative session in 2027. Historic Commission Minute Orders, Historic Blue Star highways, and Odd History memorial highways are kept track of by TRF but legacy memorial highways that may not have signage. These are represented by "Other" in the field DES_TYPE.
