TxDOT's 25 Districts are geographic subdivisions of the state, each responsible for planning, contruction, 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 a generalized boundary is needed for some types of analysis where it is important to preserve such relationships.Date valid as of: December 2017Publish Date: November 2018Update Frequency: Static. |
