Feedback Needed On I-70/Exit 203 Frisco Interchange Improvements Study

The Colorado Department of Transportation (CDOT) invites Summit County communities to participate in public engagement for the I-70/Exit 203 Frisco Interchange improvements study. Community members, stakeholders, motorists, and others are invited to view study results (in PDF, video, and image form) and submit feedback. Please see further below for background information and goals for the study.

More Info and How to Provide Feedback

A recorded presentation and PDF of the study results are available for viewing, as well as an image of the proposed concept. Comments and questions may be submitted through July 8, 2020 via email.

Virtual Public Outreach

Note: The majority of the presentation reviews Exit 203 and possible improvements to the interchange.

Due to current limitations on public events during the novel coronavirus pandemic (COVID-19), CDOT is providing virtual opportunities for public engagement. Information about this study is shared and updated on the study website (click here to view). Virtual public engagement includes, but is not exclusive to, the following process:

  • public notification in local newspaper
  • press release announcement for local media
  • emails to project stakeholders
  • public notification on CDOT’s Facebook and Twitter pages

All methods will alert the public and stakeholders to the opportunity to review the study details and how to provide feedback. To send feedback on this study, please email CDOT will document, record and review comments. Comments will be considered in the final design. CDOT encourages public input on all projects.

Project Goals

The overall purpose of the project is to improve safety, mobility, and operations on I-70 and at the CO 9 / Frisco Interchange.  The project aims to decrease the number of accidents related to the downhill portion of eastbound I-70 between Frisco and Silverthorne and reduce the large speed differential on westbound I-70 caused by congestion from the exit ramp at the Frisco interchange (EXIT 203).  These operational problems, including those caused by truck chain up areas, will be addressed by the feasibility study. Preliminarily, this project is intended to address the following as part of the feasibility study improvements:

  • Minimize environmental impacts
  • Follow context sensitive guidelines and principles
  • Improve Safety, Mobility, and Operations on I-70 and at Exit 203 (Frisco)

The I-70 Mountain Corridor, a lifeline for Summit County and the Town of Frisco, bears heavy demand from both recreational and local travelers. The roundabout at Exit 203 lacks capacity now and demand is growing rapidly. Steep downhill conditions between Exits 203 and 205 create dangerous speed differentials between slow-moving commercial vehicles and the general public and the chain-up overlook area lacks efficiency and capacity. CDOT desires to improve safety, mobility, and operations on I-70’s eastbound lane, and on the Interchange and intersections at Exit 203 while coping with ever-present funding challenges.

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:



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.


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.
