The reports generated on the Roadway Reports tab are the official statistics published annually by the CDOT Division of Transportation Development (DTD). The reports are published on July 1st of each year and reflect changes reported by DTD through December 31st of the previous year. All Roadway Report tabs reflect data generated by DTD for state highways except for the 'City/County' tab; this information is calculated using data received annually from cities and counties for Highway User Tax Fund (HUTF) reporting purposes where mileage is reported for all city streets and county roads that are open, used, and maintained.
