I-25 and Santa Fe Drive

This project began in June 2014 and is scheduled for completion in spring 2017. This is the third phase of improvements in this area. Phases 1.2 and 1.3 were combined as a bridge replacement project that replaced the structures on I-25 over Santa Fe Drive.

In phase 1.4, crews also will construct a bridge over the South Platte River to carry southbound I-25 off-ramp traffic onto southbound Santa Fe Drive.

In addition, this project will:

  • Widen Alameda Avenue at Santa Fe Drive/Kalamath.
  • Improve safety for the traveling public in this area.
  • Help to reduce congestion and improve mobility in this heavily traveled section of the metro area.
