The Route: Arizona to Colorado

This route guide outlines a common and efficient trucking route from Arizona to Colorado. The specific origin and destination points within each state will influence the precise mileage and timing, but this provides a general overview.

The primary Interstate Highway used is I-17 North to I-40 East within Arizona, then I-25 North to reach Colorado.

• Starting in Arizona: Begin traveling North on I-17. Consider your point of origin in Arizona to optimize fuel and mileage. If starting in Southern Arizona (e.g., Tucson), I-10 East to I-25 North through New Mexico and then North is also a viable, though less direct, option. This guide assumes the I-17/I-40/I-25 route.
• Transition to I-40: Continue on I-17 until it merges with I-40 East.
• Crossing into New Mexico: From I-40E, you'll cross into New Mexico.
• Transition to I-25: Continue on I-40 East until you reach I-25 North.
• Entering Colorado: I-25 North will take you directly into Colorado, connecting you to major cities like Pueblo, Colorado Springs, and Denver. The northern regions of Colorado can be accessed via connecting highways from I-25.

Compliance & Permits

Drivers must ensure they are compliant with all Federal Motor Carrier Safety Regulations (FMCSRs) and the individual state regulations for Arizona, New Mexico, and Colorado.

• Weigh Stations and Ports of Entry: Be prepared for weigh stations in all three states. Specific locations to anticipate include:

  • Arizona: Keep an eye for inspection sites when transitioning between I-17 and I-40. Arizona has a Commercial Vehicle Enforcement Unit that conducts roadside inspections throughout the state.
  • New Mexico: Port of Entry weigh stations exist along I-40 East and along the I-25 corridor. Be aware of signs indicating mandatory stops.
  • Colorado: Multiple weigh stations are located along I-25. Be prepared to stop when indicated.

• Permits:

  • New Mexico Weight Distance Tax (WDT): If your vehicle exceeds 26,000 pounds GVW, you are required to have a New Mexico WDT permit. It is based on the weight of the vehicle and the distance traveled in New Mexico. Failure to have one can result in fines.
  • Always check for the need of any temporary oversize/overweight permits based on your load characteristics. Contact each state's DOT for the most up-to-date requirements.

Risks & Hazards

• Arizona: Extreme heat is a significant risk, especially during the summer months (June-August). Ensure your vehicle's cooling system is functioning correctly and that you stay hydrated. Dust storms ("haboobs") can also reduce visibility on I-40.
• New Mexico: Similar to Arizona, heat is a hazard in the summer. Strong winds can affect vehicle handling, especially for high-profile vehicles.
• Colorado: The Rocky Mountains present unique challenges.

  • Winter Weather: Snow, ice, and blizzard conditions are common from late fall through early spring. Chain requirements are frequently enforced on mountain passes along I-25. Check road conditions and weather forecasts before you go, and be prepared to chain up if necessary.
  • Mountain Driving: Steep grades, sharp curves, and altitude can affect vehicle performance and driver fatigue. Use lower gears when descending, and take breaks to avoid altitude sickness.
  • Flash Flooding: During the monsoon season (July-September), flash flooding is possible in canyon areas, particularly in Southern Colorado.
  • Wildfires: During dry months, wildfires can break out and affect visibility and traffic. Be aware of fire restrictions and closures.
