Travel Impacts - Oct. 10 2025

As we move into the colder months, there will be limited maintenance activities happening on I-70 and the ramps that will impact travel.

Activities could include:

  • General roadway maintenance, refresh striping, pothole, guardrail and sign repair as needed
  • Graffiti removal

It is also important to be prepared for travel in snow and ice. Please make sure you consider the following items prior to traveling in inclement weather:

  • Ensure all windows on your vehicle are clear and you have good visibility
  • Ensure you have snow tires, chains or 4-wheel drive in your vehicle
  • Do not pass snowplows and give them space to do their work
  • If you don’t have to go out, avoid travel
