TxDOT maintains a spatial dataset of roadway polylines for planning and asset inventory purposes, as well as for 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.
