Bridge Deck Rehabilitation to Follow in the Near Future

DENVER – In a recent bridge inspection that took place earlier this week, Colorado Department of Transportation (CDOT) bridge engineers determined that portions of the northbound I-25 bridge deck over Santa Fe Drive need to be rehabilitated due to deteriorating concrete.

The repairs include removing the existing asphalt, removing the deteriorated concrete, replacing the bridge deck with new concrete, paving, and striping. The majority of the repairs will take place in the right lane of northbound I-25 with additional work taking place in the other lanes of northbound I-25 over Santa Fe Drive.

Prior to the bridge deck rehabilitation, starting tonight, crews will begin making immediate repairs by shoring the I-25 bridge deck to prevent concrete from falling onto Santa Fe Drive from the bridge above. As a result, up to two lanes of southbound Santa Fe Drive will be closed tonight, April 15th, from 8 p.m. to 5:30 a.m. Additional lane closures may be required during the same hours tomorrow night if crews cannot complete the shoring tonight. I-25 should not be impacted by this work.

The bridge deck rehabilitation will begin once CDOT has secured a contractor to do this work. This work will likely impact traffic on northbound I-25 as well as both directions of Santa Fe Drive at some point in the near future. A plan for how this work will be completed, when and the cost of the rehabilitation is still under development.

The northbound and southbound I-25 bridges over Santa Fe Drive were both constructed in 1958 and are two of Colorado’s structurally deficient bridges in poor condition. The stretch of I-25 carries over 200,000 vehicles a day.

CDOT is in the process of designing a project that will ultimately replace both I-25 bridges over Santa Fe Drive. The project is estimated to cost between $65 and $75 million, however a schedule for replacing these bridges has not yet been determined.
