TxDOT's 25 Districts are geographic subdivisions of the state, each responsible for planning, construction, and maintenance of on-system roadways within its administrative boundary. Each district is a conglomeration of several Texas counties. Area Engineer and Maintenance Section Offices are subdivisions of a district. This version utilizes a generalized boundary along the coast, which is sometimes necessary for analysis in which it is important to encompass segments of roadways that travel over water. Roadways on bridges or causeways that span intracoastal waterways are not covered by detailed polygons that precisely follow the coastline, therefore this generalized boundary layer is needed for some types of analysis where it is important to preserve such relationships.

This dataset was created by TxDOT for internal purposes. TxDOT is not the authority for county boundary data for the state. These features were digitized by TxDOT from georeferenced USGS topo maps to enable the classification of roadway attributes for the purposes of satisfying federal and state reporting requirements, and to serve as a base layer for TxDOT's cartographic products. This version utilizes a generalized boundary along the coast, which is sometimes necessary for analysis in which it is important to encompass segments of roadways that travel over water.

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.

This dataset contains a single point for each TxDOT office location, including: State Headquarters, District Headquarters, Area Engineer Offices, Maintenance Offices and Maintenance Yards, Special District Offices, Travel Information Centers, Safety Rest Areas, and Vehicle Title and Registration Offices. This dataset does not included roadside picnic areas. Generally point locations falls near the entrance to each facility, near the front door, or at the centroid of the facility. Point locations for Travel Information Centers and Safety Rest Areas are located at the beginning of the exit ramp. Support Services Division is the Office of Primary Responsibility (OPR) for this data. Tabular data was provided to TPP and converted to GIS format then provided to local district personnel for review, edit, and comment.

MCTX House Districts. (Updated: 07/09/15)

This is a road lidar data collection for developing road elevation models and road inundation mapping methodologies, a joint work between ORNL and The University of Texas at Austin. This dataset is generated as part of the flood transportation infrastructure, partly funded by the NOAA CIROH project. ORNL is a project partner for high-performance computing-empowered flood inundation mapping methodology R&D. The dataset is computed using a GPU-accelerated lidar data processing workflow developed at ORNL. The lidar data source is from TxGIO, the state lidar data collection site. The output dataset is in two formats: laz and copc. It is organized by TxDOT's maintenance sections, covering the Austin District. Data size: 3.86 billion road lidar points, 1.67% of the entire lidar data input Projection: EPSG:32614 (WGS84/UTM zone 14N) Website: https://web.corral.tacc.utexas.edu/nfiedata/road3d/austin_district/AustinMaintenanceSections_H_epsg6343_V_epsg5703/ LICENSE FOR USE -- MAPS AND DATA DISCLAIMER This resource is shared under the Creative Commons Attribution CC BY, http://creativecommons.org/licenses/by/4.0/ MAPS AND DATA DISCLAIMER The Oak Ridge National Laboratory (ORNL) shall not be held liable for improper or incorrect use of the data described or information contained on this map or associated series of maps.

A regional mobility authority boundary (RMA) is a political subdivision formed by one or more counties to finance, acquire, design, construct, operate, maintain, expand or extend transportation projects. These projects may be tolled or non-tolled. Counties forming an RMA do not have to be adjacent to one another. The service area of an RMA may overlap with another RMA (e.g. an individual county may form its own RMA and may also be part of another RMA). Fannin County was added to Sulphur River RMA as per Minute Order number 114957 dated June 29, 2017.Update Frequency: As NeededSource: Transportation Planning and Programming Division (TPP) | Data ManagementSecurity Level: PublicOwned by TxDOT: FalseRelated LinksData Dictionary PDF [Generated 2025/03/17]

This map contains the 4 Regional Areas: Border and Permian Basin, Central Texas, Coastal and East Texas, North Central and West Texas and the 16 Regions of the TCEQ. The areas for this data was obtained from TXDOT county boundaries (no coastal detail). General purpose use is to delineate TCEQ Region boundaries on maps and other products. Originating feature class was digitized by TXDOT at 1:24,000 using DRGs (USGS Topos) in the NAD 83 Datum.
