Kennewick, WA → Vancouver, BC

Your journey from Kennewick to Vancouver, BC will take you on a fascinating northbound route of approximately 279 miles that typically requires five and a half hours of driving time. You'll begin by heading north on I-182 before merging onto I-90, which carries you through the heart of Washington state's interior landscape. The route eventually transitions to US-395 North as you leave the Columbia Basin behind, then continues through Washington's transition zone before crossing into British Columbia where you'll connect to BC Highway 97 and ultimately Highway 1, which delivers you straight into the Vancouver metropolitan area. This drive effectively takes you from the semi-arid plateau country of central Washington through increasingly forested terrain into the lush Pacific Northwest landscape of southwestern British Columbia.

The terrain and geography shift noticeably as you progress northward. You'll start in the relatively flat to gently rolling terrain of the Tri-Cities area, then experience gradually increasing elevation and vegetation changes as you approach the North Cascades region. The landscape transforms from sagebrush and grasslands into dense coniferous forests, with the Okanogan National Forest becoming increasingly visible. Notable towns along your route include the charming community of Omak, Washington, and the smaller Canadian communities like Princeton and Merritt before you descend into the populated lower mainland approaching Vancouver.

Practically speaking, you'll encounter varying road conditions and driving environments. The initial interstate stretches are well-maintained divided highways ideal for efficient driving, while the central sections around US-395 pass through more rural terrain with occasional small-town traffic. As you enter British Columbia, expect the landscape to become more mountainous with moderate elevation changes, particularly as you approach Highway 1 near Kamloops. Urban congestion becomes a factor in the final hour as you navigate into Vancouver's sprawling metropolitan area.

For the most pleasant driving experience, plan this route during late spring through early fall when roads are clear and visibility is excellent. Winter conditions can be challenging, particularly in the mountainous sections of British Columbia, where snow and reduced visibility may significantly impact travel times and require additional caution.

Seasonal Driving Considerations
