Seasonal Notes
Summer travel usually means heavier construction, hotter rest stops, and busier weekend traffic around major cities.
Winter travel shortens daylight, so a route that looks manageable on paper can feel much longer after dark.
Holiday weekends tend to make both departure and arrival windows slower than the raw route time suggests.
Time zone
Same local time
Origin and destination are on the same clock, so arrival timing is easier to judge at a glance.
Temperature spread
14 degrees cooler at arrival
A meaningful temperature swing is a good cue to rethink layers, water, and how soon you want to arrive.

Grand Coulee is a city in the Columbia River Plateau of Washington State. It is on the shore of Lake Roosevelt just above the Grand Coulee Dam, the largest hydroelectric power producer in the United States.
This guide includes the neighboring communities of Electric City and Coulee Dam.
Bellevue is a city in the Puget Sound region of Washington state, just across Lake Washington from Seattle. Bellevue had a population of 150,000 in 2021, making it the largest city on the Eastside of King County.
Bellevue is perhaps the most ritzy part of the Seattle metro area, mainly due to the presence of Microsoft at nearby Redmond and other tech companies occupying the downtown office towers. The dense downtown has much of the region's upscale and luxury retail. It also has many neighborhoods comprised of large houses, and excellent vistas of the water for the lucky few. It is generally considered more pleasant and safe than Seattle, if blander, though the influx of international tech workers has led to a vibrant Chinese community.
