Yep.
The current supercharger location is right about 2.0 miles from I-80 (east or west). The new location is right about 1.9 miles from I-80 (to/from the east), worse to/from the west (as noted above).
So, the new site is really no improvement in off-the-freeway distance, but V3 charging speeds is always a bonus, and especially not worrying about power splitting. However, the old site is at a decent Hy-Vee, with good food choices like pizza and Asia. So, if you have a little extra time, the old site really isn’t bad (unless you are a huge Runza fan), and is only 3-4 minutes off the freeway.
