TxDOT Maintenance Section Boundaries

Maintenance Section Boundaries are derived from the Maintenance Section Routes and includes the full county, or counties, those routes may be within and any neighboring portions of counties those routes may extend into. Maintenance Section Offices are the second administrative subdivision under TxDOT Districts and Area Engineer Offices. The Geospatial Roadway Inventory Database application (GRID) is the "system of record" for storing roadway maintenance designation. The maintenance office designation is coded onto every on-system (state owned) road as a linear feature.
