Central 70 Community Outreach History

Public Information History At-A-Glance (Download a PDF version)


CDOT and RTD together with the FHWA initiated a joint study effort called the I-70 East Corridor Environmental Impact Statement (EIS).


The highway and transit elements of the Central 70 Corridor were separated into two independent projects, reflecting that they serve different travel markets, are located in different corridors, and have different funding sources.


CDOT released a Draft Environmental Impact Statement with 4 alternatives (including a realignment of the highway). No preferred alternative was identified due to a lack of support for any of the four alternatives.


CDOT and FHWA formed the Preferred Alternative Collaborative Team (PACT) consisting of 26 stakeholders from federal and state agencies, local governments, and community and business representatives to help identify a preferred alternative.The PACT met 13 times over the course of a year, and though consensus was not reached, the process helped CDOT focus on the existing alignment alternative.


City of Denver led a community outreach process largely focused on finding a different location for Swansea Elementary School.  Process found insufficient support for moving the school.


CDOT re-examined previously considered alternatives and developed the Partial Cover Lowered (PCL) option to address concerns over the school location near the highway. This began a two-year community outreach process to seek input on this new concept.  Over 800 people attended a series of corridor-wide meetings over this period. CDOT also initiated monthly community leaders meetings.


CDOT released the Supplemental Draft EIS (SDEIS) which includes the new PCL alternative. Outreach includes three public hearings, the opening of a project office in the neighborhood, and door-to-door contact to reach homes closest to the highway.


Continued outreach on key elements of the project, including proposed mitigations, cover design, and status of a public-private partnership. Outreach included community leaders meetings, corridor-wide meetings, and door-to-door outreach.

2016 Release of Final EIS, followed up a 45-day public review period and two public hearings, completing the study process. Continued outreach on aesthetics, cover design and implementation of mitigations. Released three drafts of the Request for Proposals to the four developer teams. Supported the 'duct-work community art project.

"'duct-work" is what happens when you combine talented Denver urban artists with ample paint and large blank walls as canvases. Denver Arts and Venues, together with local sponsors, provided funding for a group of local urban artists to paint murals under the I-70 viaduct between Brighton Boulevard and York Street.

In late-September, the project transformed the dark and shadowy viaduct into a work of art for the remaining years before its demolition.
