Texas City Boundaries

IMPORTANT! This layer has been created and maintained for TxDOT-specific purposes only - primarily for use in the Geospatial Roadway Inventory Database (GRID). This layer is not the authoritative source for city boundaries. The authoritative dataset is maintained by the Texas Comptroller of Public Accounts (CPA). City limit boundaries are maintained to enable the classification of roadway inventory attributes, satisfy federal and state roadway reporting requirements, and serve as a base layer for TxDOT's cartographic products. The data was created by the Transportation Planning and Programming Division of TxDOT in the Data Analysis, Mapping and Reporting Branch. Updates are made based on updates to the CPA layer.
