About

Transportation impacts our lives each and every day from the bridges you cross, to the signs you read, to the construction reports you follow. A good transportation system allows us to get to work, recreational activities and health care and it allows companies to provide products and services to consumers. The Colorado Department of Transportation (CDOT) exists to ensure that Colorado has a safe and efficient highway system by building and maintaining interstates, US highways and state highways.
