Northbound I-25 traffic at Exit 59 will switch to detour pavement on October 17.

October 17, 2019

Huerfano, COStarting late Thursday, October 17, northbound I-25 traffic at Exit 59 in Huerfano County will be routed onto new detour pavement and then onto the left southbound lane from MP 58.08 to MP 59.01. Southbound I-25 will be reduced to a single (right) lane through the work zone. The new lane configurations are necessary while crews remove and replace the northbound bridge. The southbound bridge has just been completed and is fully operational.


CDOT and contractor, TLM Constructors are replacing the bridges at I-25, Exit 59 in Huerfano County to meet current FHWA (Federal Highway Administration) bridge structure, load and safety guidelines. Built in 1958 of prestressed concrete, the bridges are being reconstructed with reinforced concrete and steel to maximize longevity and structural integrity to support increased traffic demands along the I-25 corridor. 

The two-phase project supports CDOT’s 40-year statewide multimodal plan to enhance the safety, mobility, and economic vitality of the state and the new Whole System - Whole Safety initiative.


The project is located on I-25 at Exit 59, Butte Creek from MP 58.8 to MP 59.01 in Huerfano County.


CDOT anticipates medium travel impact to motorized traffic on north and southbound I-25 at Exit 59, Butte Creek. These impacts include: 

  • Northbound detour is in place from MP 58.8 to MP 59.01 (see schematic).
  • Northbound traffic will be detoured onto pavement and then onto the left southbound lane through the construction zone until the northbound bridge is complete.
  • Southbound traffic is reduced to a single right lane through the work zone.
  • >The I-25 northbound ramp to Exit 59 has been reconfigured. Lanes are narrowed and caution is advised.
  • Speeds are reduced in the work zone and fines are doubled.
  • Width restrictions of 12 feet have been imposed until further notice. 
  • CR 103 will be maintained as a one-lane, signal controlled road during the entire duration of the project.
  • Ongoing maintenance requires restriping with the use of attenuator trucks to pace traffic. Some delays should be expected.
  • Detours, access to CR 103, lane closures, and other traffic notices are posted weekly on


The project kicked off on November 1, 2018 and is expected to last until spring 2020. Working hours are Mon. to Fri. 7 a.m. to 6 p.m. No holiday or weekend work is expected.

The following tips are to help you stay safe while traveling through maintenance and construction work zones.

  • Do not speed in work zones. Obey the posted speed limits.
  • Stay Alert! Expect the unexpected.
  • Watch for workers. Drive with caution.
  • Don't change lanes unnecessarily.
  • Avoid using mobile devices such as phones while driving in work zones.
  • Turn on headlights so that workers and other drivers can see you.
  • Be especially alert at night while driving in work zones.
  • Expect delays, especially during peak travel times.
  • Allow ample space between you and the car in front of you.
  • Anticipate lane shifts and merge when directed to do so.
  • Be patient!


Travelers are urged to “know before you go.” Gather information about weather forecasts and anticipated travel impacts and current road conditions prior to hitting the road. CDOT resources include:


To heighten safety awareness, CDOT recently announced its Whole System — Whole Safety initiative. This initiative takes a systematic, statewide approach to safety combining the benefits of CDOT’s programs that address driving behaviors, our built environment and the organization's operations. The goal is to improve the safety of Colorado’s transportation network by reducing the rate and severity of crashes and improving the safety of all transportation modes. The program has one simple mission—to get everyone home safely.


CDOT has approximately 3,000 employees located throughout Colorado, and manages more than 23,000 lane miles of highway and 3,429 bridges. CDOT also manages grant partnerships with a range of other agencies, including metropolitan planning organizations, local governments and airports. It also administers Bustang, the state-owned and operated inter-regional express service. Governor Jared Polis has charged CDOT to further build on the state’s inter-modal mobility options.
