Construction Begins on Colorado Highway 101 Bridge Replacement Project

Travel Advisory

November 3, 2020 - Southwestern Colorado

BENT COUNTY — Colorado Department of Transportation and contractor, Lobato Construction, Inc., will begin construction on Colorado Highway 101 starting November 2020. The project will replace two timber bridges with concrete box culverts on CO 101 approximately 20 miles south of Las Animas at mile points 19.35 and 19.98. Project completion is anticipated by summer 2021, but is weather dependent.


During the duration of the project, motorists can expect shoulder and single lane closures. Initially, flaggers will guide motorists while the detours are being built. A single lane detour will be constructed adjacent to each bridge site and will remain in place during the removal and replacement of the bridges from December 2020 through spring 2021. Temporary traffic signals will be used to control the flow of the single lane traffic.

Safe transportation infrastructure is essential for emergency first responders and freight drivers as Colorado navigates the COVID-19 pandemic. With that in mind, construction continues on CDOT projects with social distancing and other measures to reduce COVID-19 exposure on the worksite. The Colorado Department of Public Health and the Environment has promulgated guidelines for construction activities. Gov. Polis announced an emergency, temporary stay-at-home order for all of Colorado, which went into effect Thursday, March 26. With this order, the public is urged to #DoYourPartCO and avoid all nonessential travel. With fewer vehicles on the roads, CDOT crews will be able to work more efficiently and safely.


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!


The CDOT Whole System — Whole Safety initiative is designed to heighten safety awareness by taking a systematic statewide approach to safety by combining the benefits of CDOT’s operations, programs addressing driving behaviors, and our built environment. 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 interregional express service. Governor Polis has charged CDOT to further build on the state’s intermodal mobility options.
