Project Progress

Two years after the groundbreaking, the I-25/Ilex Street to City Center Drive project construction is progressing smoothly.

Project progress to this point includes:

  • Construction of the new D Street extension on the west side of Santa Fe Avenue.
  • Storm drainage improvements at Kelly Avenue.
  • Deck replacement on the northbound I-25 bridge over Indiana Avenue.
  • Median repaving on I-25 over City Center Drive bridge.
  • New bridge structure work on I-25 over Thomas Phelps Creek and UPRR.
  • Continuing deck removal, replacement and rehabilitation on the Northern Avenue bridge.
  • Steel repairs and rehabilitation work on the historic US 50C truss bridge.
  • Completion of pier and pier cap placement for the future Alan Hamel/UPRR bridge.
  • Setting of girders (beams) on the new box girder bridge on I-25 over Gruma Drive.

The project is expected to be completed in 2018.

Schedule and Traffic Impacts

Normal working hours are from 7 a.m. - 7 p.m., Monday through Friday. There will be some nighttime and weekend work as needed.

Please use caution and stay alert while traveling through the construction zone.


  • Please be advised that traffic is reduced to a single lane in each direction on Santa Fe Avenue (US 50C) under Interstate-25 as northbound lanes are closed and traffic is shifted onto southbound lanes. Twelve-foot width restrictions will be in place.
  • The new traffic configuration will be in place 24 hours-a-day, 7 days-a-week through Sunday, July 16. Flaggers will be present during normal working hours of 7 a.m. to 7 p.m. Slight traffic delays are expected, speeds will be reduced to 25 MPH, and motorists are urged to use extra caution while traveling in the new traffic pattern.

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.
