Culvert improvement work to begin on CO 184 between Mancos and Dolores

Travel Advisory

October 8, 2020 - Southwestern Colorado

MONTEZUMA COUNTY ― The Colorado Department of Transportation will begin a culvert rehabilitation project at four locations on CO Highway 184 between Mancos and Dolores, in southwestern Colorado as part of its statewide effort to rehabilitate culverts in need of repair. The work is scheduled to take place over one and a half  months, starting October 15, through the end of November. Contractor, America West Construction, LLC., has been hired to perform the work.

Sites 1-5 on CO 145 in Montezuma County

The five project locations include:

  • Site 1 – Highway 184 MP 11.73
  • Site 2 – Highway 184 MP 12.29
  • Site 3 – Highway 184 MP 12.57
  • Site 4 – Highway 184 MP 12.83
  • Site 5 – Highway 184 MP 14.01

All Sites will be repaired by use of spin casting (CCCP), which uses centrifugal force to uniformly line the inside of each pipe with a high strength mortar.  This method of rehabilitation eliminates the need to dig up the roadway to replace the culvert, thus reducing the project cost and impact to the traveling public.

The goal of the project is to increase the longevity of each irrigation conveyance pipe to prevent failures and erosion of the embankment(s), while ensuring the safety of the travelling public.

Travel Impacts

Most of the work will occur off the roadways. However, within the construction zone there will be reduced speeds, daily shoulder closures, and traffic devices denoting the area. Occasional delays of up to 10 minutes may be encountered. Work will be performed only during daytime hours, approximately 7 a.m. to 5 p.m., and may include some Saturday work. Motorists should also be aware of flaggers, construction workers and heavy equipment on and along the roadway.

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:

Remember: Slow for the Cone Zone

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!

COVID-19  

Safe transportation infrastructure is essential for all of us, particularly for emergency first responders and freight drivers as Colorado navigates the COVID-19 pandemic. With that in mind, CDOT maintenance and construction crews follow social distancing and other health safety measures to reduce COVID-19 exposure on the worksite. The Colorado Department of Public Health and Environment announced guidelines for construction activities. The public is urged to join the campaign for #DoingMyPartCO by practicing social distancing and wearing face masks. As traffic returns to normal levels, motorists must drive cautiously and heed the speed limit so all of us can return home safely. 

Whole System. Whole Safety.

In early 2019, CDOT announced its Whole System—Whole Safety initiative to heighten safety awareness. 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.
