Residents, environmental groups press Transportation Commission on I‑270 DEIS; Adams County leaders urge timely corridor fixes

Chair Cook opened a Transportation Commission meeting that drew extensive public comment on CDOT’s I‑270 corridor project and the agency’s concurrent 10‑year plan draft. Adams County officials, trucking and fuel industry representatives, and local business owners urged the commission to keep momentum on I‑270 improvements to preserve jobs, freight reliability and local access.

"To access this opportunity, I depended on I‑270 every single day," Adams County Commissioner Julie Duran Moloca said, describing long daily commutes that she said undercut economic opportunity for working families. Adams County Commissioner Steve Odorizio told the commission the corridor is central to Colorado’s logistics industry and pressed for a solution that improves access while addressing environmental and neighborhood concerns.

Environmental groups and neighborhood advocates urged a different path. Alexandra Schluntz, senior attorney for Earthjustice, told the commission that "widening the corridor would increase pollution without reducing congestion," and said decades of evidence show lane additions can induce demand and fail to solve urban congestion. Green Latinos and Conservation Colorado asked CDOT to include a "Healthy Communities No Widening" alternative in the DEIS and to extend the DEIS comment window beyond the holidays.

"Colorado urgently needs transportation investments that align with our climate goals that move people, not just cars," Renee Larate of Conservation Colorado said, urging permanent funding for regional bus service and measures such as differential tolling that would prioritize freight and transit while protecting local drivers.

Several residents from Elyria‑Swansea, North Denver and Wellby described disproportionate air‑quality and health burdens and questioned whether highway widening would benefit non‑drivers. "Nondrivers make up around 30% of Coloradans," Alejandra Castaneda, a pedestrian‑dignity organizer, said, pressing for transit, safer walking routes and investment that does not assume car ownership.

The commission and CDOT staff responded by reiterating process points: Director Lou said the I‑270 draft environmental impact statement (DEIS) is expected to publish in the Federal Register imminently and that, under NEPA, the DEIS will open a formal comment period (CDOT indicated a 60‑day period is planned). Several speakers and organizations asked CDOT to delay publication or, at minimum, extend the comment period to 120 days to allow fuller community review and participation.

The public comments at the meeting highlighted a split in local priorities: business and freight interests emphasized safety, reliability and the economic costs of delay; frontline community groups and environmental organizations emphasized health, equity and alternatives emphasizing transit, tolling and non‑widening options. Director Lou emphasized that NEPA requires analysis of alternatives submitted during the DEIS comment period and that CDOT has included mitigation and transit considerations in the range of alternatives under study.

Next steps: CDOT expects to publish the draft EIS in the Federal Register and open a formal comment period; stakeholders said they will submit formal comments and ask the department to analyze the no‑widening alternative and consider extending the comment window.
