Colorado Office of Transportation Safety

The Colorado Department of Transportation is responsible for a 9,161 mile highway system, including 3,775 bridges. Each year, this system handles over 28.6 billion vehicle miles of travel. Although the Interstate system accounts for only about 10 percent (915 miles) of the total mileage on the state system, 40 percent of all travel takes place on our Interstate highways.

CDOT's highway construction program attracts private contractors and the low bidder is awarded the project and in turn is responsible for construction of that project. This partnership between government (CDOT) and business works well as we improve and expand our transportation system.

CDOT maintenance forces take care of the highway system, plowing snow and repairing pavement. Last winter, these men and women plowed 7.1 million miles of highway. They also repaired road damage and potholes, using more than 270,947 tons of asphalt and 196,646 gallons of liquid asphalt in preservation activities. But CDOT is more than roads and bridges.

The Division of Aeronautics supports aviation interests statewide, including grants to help improve local airports. CDOT's Transit Unit provides assistance to numerous transit systems in the state. And the Office of Transportation Safety helps local law enforcement agencies with special funds to apprehend drunk drivers and increase use of safety belts.

CDOT's Vision:
