In 2000, the Federal Highway Administration (FHWA) and CDOT initiated an Environmental Impact State Study (EIS) as part of the National Environmental Policy Act (NEPA) of I-25 through Pueblo, Colorado. This project was designed with respect for the traditions and trends of the Pueblo community, and is consistent with the New Pueblo Freeway EIS and aesthetic guidelines established for the I-25 corridor through Pueblo.

CDOT started this project in July 2015. The first segment of construction consists of replacing bridges on I-25 between Ilex Street and City Center Drive. Work includes rehabilitation of bridges on:

  • northbound I-25 over Santa Fe Avenue (US 50C);
  • I-25 over Indiana Avenue;
  • Santa Fe Avenue (US 50C) over the Arkansas River; and
  • Northern Avenue and Mesa Avenue over I-25.

The project was designed with respect for the traditions and trends of the Pueblo community. One section of the recently installed D Street wall panels displays the image of a baseball player, paying homage to Pueblo's beloved pastime.

The I-25/Ilex Design-Build project team is taking care to comply with environmental requirements and develop processes so work activities are protective of human health and the environment.

This project receives 60 percent Funding Advancements for Surface Transportation and Economic Recovery (FASTER) funds and 40 percent Responsible Acceleration of Maintenance and Partnership (RAMP) funds.

  • FASTER funding legislation pays for safety projects and repairs for structurally deficient bridges as well as safety improvements to Colorado's key corridors.
  • RAMP program funds help move projects forward by funding multi-year projects based on year of expenditure, rather than saving for the full amount of a project before it starts.
