History

:''Source: CDOT'' The Colorado Department of Transportation has its roots in 1909, when the first highway bill was passed by forming a three-member Highway Commission to approve work and allocate funds. The Commission first took their post on January 1, 1910. In 1917 the State Highway Fund was created and the State Highway Department was formed. In 1935, Highway Department employees were joined by 44 new co-workers selected from among 7,500 applicants to become the first members of the Colorado State Highway Courtesy Patrol. The Patrol became a division of the Highway Department. In 1947, the first National System of Interstate and Defense Highways was approved by the federal works administrator. In Colorado, approved routes included all of

, by requiring transportation planners to calculate any emissions associated with a project and mitigate accordingly. The policy was approved by the State Transportation Commission on a 10-1 vote. Apart from environmental benefits, this policy could deliver $40 billion in economic benefits, including fewer traffic collisions. Under this policy, the governor-appointed Colorado Transportation Commission would have authority to restrict funding for use only on climate-friendly transportation projects if the CDOT or a regional planning authority fails to meet its emissions reduction target. Lew stated that this policy allows for capacity increases, but that major projects would require offsets in the form of climate-friendly additions. Examples include the
