Road Construction and Accidents

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

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.
