About CDOT

100 Years of Transportation

Centennial Logo

In January 1910, the first formal Colorado state government agency charged with developing a state road system began operations.

In 2010, CDOT celebrated 100 years of state transporation agencies. Colorado's transportation agencies have always been public, working together with citizen taxpayers, a series of governors, legislators, and county and local governments to meet a greater public need.

The way may not have always been smooth, but together, much more was achieved and maintained than could have ever been accomplished individually.
