CDOT begins US 34 north of Granby resurfacing project

Travel Advisory

June 23, 2020 - Northwestern Colorado - Speed limits to be strictly enforced

GRAND COUNTY- The Colorado Department of Transportation and contract partner Elam Construction begins preparations this week for the US 34 north of Granby resurfacing project. 

Preparation work will take place along two roadways, US Highway 34 and US Highway 40 near Granby.

Construction crews will begin the surface treatment project the week of July 7. Work will begin on US 34 at Mile Point 0 and will continue for 15 miles to MP 15. On US 40, the work will take place from MP 210.9 to MP 211.25 which is near the intersection of US 34 and US 40. 

As part of CDOT’s Whole System — Whole Safety initiative, this project will focus on a 2.5” hot mix asphalt overlay and installing guardrail that will meet the new safety standard requirements.  The HMA will add approximately 10 years of life to the highway, a smoother road surface and will eliminate ruts and road damage.  The new guardrail will be 31” high instead of 27” high to help vehicles remain on the road more effectively, making the highway safer for the traveling public.  

Additional work will consist of shoulder work, milling and striping.  


Motorists can expect one-lane alternating traffic, 20 minute delays, reduced speeds and a 10 ft. width restriction during hours of operation.  The project will be in operation Monday through Thursday from 7 a.m. to 7 p.m. and Friday from 7 a.m. to 12 p.m. The project is expected to last until mid-November.

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:


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.
  • 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.
  • 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.
  • Be patient!


Safe transportation infrastructure is essential for emergency first responders and freight drivers as Colorado navigates the COVID-19 pandemic. With that in mind, road maintenance and 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 Environment announced guidelines for construction activities. The public is urged to join the campaign for #DoingMyPartCO by practicing social distancing, wearing face masks, staying home when possible, and avoiding nonessential travel. With fewer vehicles on the roads, CDOT crews will be able to work more efficiently and safely.


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.
