On Nov. 1, 2018, crews began a more-than-year-long project to replace two bridges at Exit 59 on I-25 and Butte Creek, north of the Town of Walsenburg. The 61-year-old bridges—one northbound and one southbound on I-25 over Butte Creek and Huerfano County Road 103— will be reubilt to meet Federal Highway Administration (FHWA) guidelines and support increased traffic along the I-25 corridor.


In phase 1, crews:

  • installed detour pavement;
  • completed drainage work;
  • removed the southbound bridge; and
  • will replace the southbound bridge.

During phase 2, crews will:

  • demolish and replace the northbound bridge (Fall 2019 to Fall 2020)

Community and media outreach has resulted in minimal traffic impacts.


  • Construction of the northbound bridge is well underway. Stage 1 of the concrete deck pour is complete and Stage 2 and 3 are pending.


  • Improved Infrastructure—Both bridges will be reconstructed with reinforced steel and concrete for added strength, longevity, and structural integrity. Ramps will be extended, and additional roadway, drainage, and infrastructure improvements are being made in conjunction with the bridge replacements.
  • Safety—Safety barriers, guardrail and end caps are in place along the detour pavement, and crews have installed a wider, safer southbound off-ramp at Exit 59 for vehicle pull-off and emergency response.
  • Advanced Technology—Crews used the latest technology to demolish the southbound bridge, and they'll continue to use these methods and materials going forward.
