I-25/Rockrimmon Bridge Preventative Maintenance Project Complete

Colorado Springs - The Colorado Department of Transportation (CDOT) has completed work on a bridge and driving surface preventative maintenance project near the Interstate-25/Rockrimmon-Nevada interchange. The $12 million project was part of the ongoing CDOT Asset Management/Bridge Preventative Maintenance Program that began approximately ten years ago to extend the life of the state’s bridge structures to 75 years. This program focuses on asset preservation and replacement and does not fund projects that increase the capacity of Colorado’s transportation system. To qualify for asset-management funding, projects must be able to demonstrate, with a quantified performance measure, the benefit of additional investment.

"CDOT's focus on Asset Management (maintaining our system) was demonstrated as a job well done for this critical and heavily traveled I-25 corridor through the heart of Colorado Springs,” explained Karen Rowe, Region 2 Transportation Director. “I-25/Nevada-Rockrimmon now provides a smooth ride and safe travel for recreational travelers, commuters, and the freight traffic that use this statewide critical corridor."    

Bridge preventative maintenance, including waterproofing and an asphalt overlay, was the primary purpose for the project. The work extends the life of the bridge structures and the overall pavement along I-25. The Interstate was widened to the median for construction phasing. The widening is also in line with future improvements and provides a safe area for stranded vehicles. 

Project activities completed:

• Maintenance of ten bridges including expansion joint replacement, waterproofing membrane, and installation of asphalt overlays to protect and extend the life of the bridge decks.

• Concrete panel replacement was performed where needed to extend the serviceable life of the overall pavement along I-25.

• Asphalt paving over existing roadway pavement and concrete bridges providing a maintainable surface and improved the ride quality.

• Safety improvements also included upgraded guardrail, restriping and wider shoulders

• A right turn lane at northbound I-25 off-ramp to Woodmen Road (Exit 139) was added for safety considerations. Motorists now have three right turn lanes from the ramp to continuous lanes on eastbound Woodmen Road. New traffic turn lights were installed.

• Permanent repairs completed at the crescent-shaped crack located in the auxiliary lane of northbound I-25, south of the Rockrimmon Boulevard exit. This area was planned to have a temporary safety overlay of asphalt, but ongoing monitoring identified that concrete panel replacement provided a stable and a permanent solution.

The majority of work took place Monday through Friday, with some weekend work. The project delivered on budget.
