CTDOT Maintenance Districts

This dataset provides polygon features representing the official maintenance district boundaries for CTDOT. Each district oversees the day‑to‑day maintenance of state highways, bridges, drainage systems, signs and markings, vegetation management, roadside cleanup, snow and ice operations, and other roadway assets within its jurisdiction. The dataset is intended for use in mapping applications, operational dashboards, internal planning tools, and public‑facing GIS services. Boundaries are maintained by CTDOT’s Bureau of Highway Operations with support from Enterprise GIS.
