Not an X driver, but it should be easy one way as long as you have destination charging. Maps says 130 mi via I-90, but 112 mi via US2. The time is probably a wash unless weekend ski traffic to Stevens Pass. I prefer US2 route due to the much nicer scenery, plus if you need more charge, stop at the Monroe SC for coffee and restroom stop. EDIT: With the Chademo adapter, there are DCQCs on both passes so definitely no problems due to lots of back up plans (e.g., Sultan, Skykomish, Snoqualmie Pass, Cle Elum, Levenworth).
It's only 128 miles. You'll be fine as long as you leave with a full charge and have charging available in Leavenworth. Generally speaking I wouldn't worry about having enough range unless your trip is >150 miles. Caveat being that for trips in the 120-150 mile range, you should at least keep an eye on the battery as you make the trip, and of course be on the lookout for unusually terrible conditions (headwind over 20mph, snow or standing water on the roadway, sub-zero temps, big elevation gains, etc.).
Starting either end of your trip with a 90 or 100% charge should get you to Leavenworth from Bellevue (or the reverse) no matter what route you take unless very unusual driving conditions exist (you are towing with a significant constant headwind in deep snow.)
No there is nothing installed, it is just pavement that is cut out filled in with gravel in a shape that would have a line of Supercharger spots then the equipment at the end. I was extrapolating where "1A" might be.
These are Supercharger cabinets. Of course, they have been removed from the site, so who knows what is going on...
