In the interest of public health and safety, CDOT will use a virtual public event room to share project information and collect comments.

The virtual event room opened today, Aug. 17, and will be accessible through Sunday, Aug. 30.

This online engagement is part of an environmental assessment being prepared to evaluate transportation improvements to I-270 in compliance with the National Environmental Policy Act. The purpose of the I-270 Corridor Improvements project is to modernize the I-270 corridor to accommodate transportation demands. This highway was constructed 50 years ago and since that time, this inner beltway for the Denver region has grown into a corridor of commerce, attracting companies in the sectors of energy, advanced manufacturing, and logistics. The highway also provides a vital connection to Denver International Airport and connects Denver to the education and research facilities along the US 36 corridor.

CDOT also manages grant partnerships with a range of other agencies, including metropolitan planning organizations, local governments and airports. It also administers Bustang, the state-owned and operated interregional express service. Gov. Polis has charged CDOT to further build on the state’s intermodal mobility options.
