Texas National Highway Freight Network
The Transportation Planning and Programming (TPP) Division of the Texas Department of Transportation (TxDOT) maintains a spatial dataset of roadway polylines for planning and asset inventory purposes, as well as for visualization and general mapping. This dataset is a subset of the published TxDOT roadway network, that represents the National Highway Freight Network as published under the FAST Act.<div><br /></div><div>Update Frequency: Annual (Sept)<br /></div><div>Source: Geospatial Roadway Inventory Database (GRID)<br /></div><div>Security Level: Public</div>
