Milestones

  • Nov. 1, 2018: Project kickoff
    Crews cleared and prepared the median to install detour pavement before removing the southbound bridge. They also striped and completed other roadway and drainage work.
  • Jan. 3, 2019: Detour pavement and safety barriers, guardrails, and end caps completed.
    Crews also built a wider, safer southbound off-ramp at Exit 59 for vehicle pull-off and emergency response.
  • Jan. 10, 2019: Southbound bridge demolition
    Crews used the latest bridge-removal technology. Ongoing bridge-removal work will incorporate leading-edge construction methods and materials.
  • Jan. 30, 2019: Piling and caisson installation
    This work is part of the initial construction of the new southbound bridge's foundation and substructure.
  • Feb. 1, 2019: Maintenance program implementation.
  • Feb. 4, 2019: Column, abutment, falsework and pier caps formation.
  • Feb. 20, 2019: Widened southbound Exit 59 off-ramp and added traffic signal.
  • March 11, 2019: Monthly maintenance program began.
  • April 1, 2019: Girder erection began.
  • April 15, 2019: Deck and asphalt construction began.
  • May 15, 2019: Deck closure pour began.
  • September 27, 2019:  Switch to full lane alignment north and southbound I-25.
  • October 15, 2019:  Completion of Phase I.
  • October 16, 2019:  Begin Phase II.
  • October 17, 2019:  Completion of northbound detour .pavement and traffic switch to detour.

  • January 2-9, 2020: Deck pan welding completed.
  • January 14-24, 2020: Completion of deck rebar placement.
  • February 22, 2020:  Stage 1 completed - northbound bridge concrete deck pour.
  • June 25, 2020 - CR 103 restored to full two-lane alignment.
  • PENDING - Final stage of northbound bridge deck pour.

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.


Phases

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.


Progress

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

Benefits

  • 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.
