The TxDOT DCIS Projects service layer is a dataset of roadway construction and maintenance projects that are either currently under construction, or are in some phase of the planning process. Projects are grouped into 4 categories: projects that are currently underway or begins soon; projects in the construct authority (begins within the next four years); projects in the develop authority (planned to begin in 5 to 10 years); and projects in the initial phases of project development (corridor studies, construction in 10+ years). The dataset excludes non-letting projects.Update Frequency: NightlySource: TxDOT Connect (TxC)Security Level: PublicOwned by TxDOT: TrueRelated LinksData Dictionary PDF [Generated 2025/05/21]
