TxDOT maintains a spatial dataset of roadway polylines for planning, asset inventory, visualization and general mapping.

The departmental map serves as a visualization of all on-system routes (those that TxDOT maintains). The routes include interstate highways, US highways, state highways, as well as farm and ranch roads.

TxDOT updates the map continually and publishes it annually.
