I-25 Bridge Replacement at Butte Creek

Project Facts

  • Cost: $7.3 million
  • Contractor: TLM Constructors
  • Timeline: November 2018 - Spring 2020
  • Location: On I-25 over Butte Creek in Huerfano County, from mile points 58.08 to 59.01Wide shot of concrete deck pour

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 – Estimated completion of northbound detour pavement.
  • October 31, 2019 – Estimated completion of Phase One.

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 (expected completion: spring 2020).

Community and media outreach has resulted in minimal traffic impacts.


Progress

  • The new southbound bridge's deck has been poured.  Superstructure components are being constructed and erected. Detour pavement is being installed in advance of the traffic switch for demolition and replacement of the northbound bridge.

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.
