December 1, 2020 - Northeastern Colorado

GREELEY -- The Colorado Department of Transportation is hosting a virtual public meeting and wants to hear your thoughts on the designs for improvements to the US 34 intersection at 35th and 47th Avenues in Greeley. 

Travel demand is increasing as local development grows. Alternative designs for both intersections aim to meet increasing travel demand, improve safety, reduce congestion and improve mobility. 

The virtual public meeting will be Dec. 9 from 6-7 p.m. and will include representatives from CDOT, the City of Greeley and the project team. Register for this public meeting through the project website at The presentation will provide background information about the project and the preferred alternatives. It will be a great opportunity for you to share your thoughts and priorities with the project team. You can still participate if you are unable to attend the meeting. A recording of the meeting will be posted to the project website and an FAQ document will be posted following the meeting. Please let us know your thoughts by commenting on the presentation or contacting us via email at [email protected] or by phone at 970-616-4008. 

Three interchange design alternatives have been reviewed for each intersection. The three alternatives for each intersection were presented in detail at the first public meeting in August. More information and recordings of the first presentation can be found on the project website. One alternative for each intersection has been selected out of the three. In this public meeting the preferred design for each intersection will be presented. 

35th Avenue Intersection

The preferred design alternative for US 34 at 35th is the partial-diamond loop. A bridge will carry US 34 traffic over 35th Avenue and drivers will use ramps to access the freeway. The 28th Street intersection will have a ¾ movement that eliminates westbound left turns with partial signalization for northbound and southbound traffic. It was rated highly for safety and multimodal accommodations.

47th Avenue Intersection

The preferred design alternative for US 34 at 47th is the diverging diamond interchange (DDI). This alternative uses an innovative interchange design that reduces crashes and congestion. A bridge will carry US 34 traffic over 47th Avenue. Drivers can access the freeway from 47th using ramps. Drivers will not need to turn left across traffic. Free flowing left turns onto US 34 access ramps can nearly double the number of vehicles that will be able to move through the interchange and onto US 34.

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.

  • Anticipate lane shifts and merge when directed to do so

  • Expect delays, especially during peak travel times.

  • Allow ample space between you and the car in front of you.

  • 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, construction continues on CDOT projects with 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 and practice social distancing, wear face masks, stay at home when possible, and avoid 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.
