This project:

  • replaced the old I-25 bridge over Arapahoe Road;
  • improved the interchange complex to reduce congestion; and
  • improved traffic operations and safety.

CDOT contracted with the David Evans and Associates/Hartwig & Associates team to complete the project design, and selected Kraemer North America as the general contractor.


In early 2014, field work was completed to gather detailed data. This included traffic counts, survey, geotechnical borings and utility locates.  Preliminary design plans were completed in February 2015. Ninety percent of the design was completed in October 2015. Final design completed the end of 2015. Construction began in May 2016 and was substantially completed by spring 2018. Find more schedule information.
