Factors Affecting Drive Time

Several factors can influence how long it takes to drive between Seattle and Portland:

Check the Washington State Department of Transportation (WSDOT) and the Oregon Department of Transportation (ODOT) websites or apps for up-to-date information on road closures and construction zones. You can find more details about the I-5 on Wikipedia’s Interstate 5 page.

Rest Stops and Breaks

Plan for rest stops, especially on longer journeys. Taking breaks to stretch, use the restroom, or grab a snack will add time to your trip but is crucial for safety and preventing driver fatigue. There are several rest areas along I-5.

Weather Conditions

Adverse weather conditions such as rain, snow, or fog can significantly reduce visibility and increase the risk of accidents. It’s important to slow down and drive cautiously in poor weather, which will naturally increase travel time.
