The Route: Missouri to Washington

This guide outlines a common and efficient trucking route from Missouri to Washington state. Please note that specific routing may vary depending on the origin point in Missouri and the final destination in Washington. This route prioritizes Interstate highways for ease of navigation and access to amenities.

Our suggested route utilizes I-70 West initially from Missouri, transitioning to I-15 North in Utah, and then I-90 West to Washington. This offers a generally direct path while leveraging major Interstate infrastructure.

• Missouri: Begin on I-70 West. Depending on the starting location, alternative routes like I-64 West to I-70 may be necessary.
• Kansas: Continue on I-70 West through Kansas.
• Colorado: I-70 West continues through Colorado, traversing the Rocky Mountains. Be aware of potential steep grades and required lower gear usage.
• Utah: Remain on I-70 West to its terminus near Green River, UT. From there, take US-6 West to Spanish Fork, UT. Merge onto I-15 North.
• Idaho: I-15 North carries you through Idaho.
• Montana: Continue on I-15 North to Butte, MT. Merge onto I-90 West.
• Washington: I-90 West carries you through the state of Washington to your final destination. Seattle and Spokane are both located on I-90.

Compliance & Permits

Compliance with state and federal regulations is paramount. Ensure all vehicle inspections are up-to-date and that the driver is compliant with Hours of Service regulations.

Be prepared for weigh stations along the route. Some key weigh stations to anticipate include:

• Colorado: Expect weigh stations on I-70 entering and exiting the state.
• Utah: Multiple weigh stations are present on I-15.
• Idaho: Weigh stations are commonly positioned on I-15 near state borders.
• Montana: Weigh stations along I-90.
• Washington: Weigh stations along I-90 as you enter the state.

Specific permits: Given the route described, running from Missouri through to Washington, and assuming you are travelling I-70/I-15/I-90, there are no specific permits (like KYU, NM WDT, etc.) that are required for this type of interstate route. However, depending on the weight of your load, you may need to obtain Oversize/Overweight permits for certain states, particularly if exceeding standard legal limits. Check each state's DOT website for specific requirements based on your load configuration.

Risks & Hazards

This route presents several seasonal weather-related risks.

• Winter (November - March): The Rocky Mountains (Colorado, Utah, Montana, and potentially eastern Washington) are susceptible to heavy snowfall, icy conditions, and reduced visibility. Chain requirements are frequently enforced. Monitor weather forecasts and road conditions closely. Be prepared to adjust your schedule or route accordingly.
• Summer (June - August): Extreme heat can be an issue, particularly in Kansas, eastern Colorado, and the more arid regions of Utah and Idaho. Ensure proper vehicle maintenance, especially cooling systems and tire pressure. Driver fatigue is also a significant risk during these months; proper hydration and rest are crucial. Wildfires are also common in the summer months, particularly in the western portions of the route; check for road closures and smoke hazards.
