I-25 Rockrimmon Bridge Maintenance & Preventative Work

Project Facts

  • Timeline: March 2018 - March 2019
  • Cost: $12 million
    ($5 million funded by the CDOT Bridge Preventative Maintenance (BPM) Program)
  • Contractor(s): Ralph L. Wadsworth Construction Company, LLC.
  • Location: between the Garden of the Gods Road exit and Woodmen Road on I-25 (The main area of work consists of the Rockrimmon-Nevada interchange complex, constructed in 2007.)

In March 2019, CDOT completed this project, for which crews extended the life of a bridge and its driving surface near the I-25/Rockrimmon-Nevada interchange. The work was part of the ongoing CDOT Asset Management/Bridge Preventative Maintenance Program, which aims to extend the lives of the state’s bridges to 75 years.

Crews also widened I-25 to the median, in line with future improvements, and to provide a safe area for stranded vehicles.
