Wiki – Largest gaps between Superchargers on US Interstates


On the Socorro, NM thread @PLUS EV asked if I had a list of gaps 140 miles or greater.

Of course I do!

I posted there, but I figured I’d create a separate thread for it.

Note that:
– I’ve included some gaps that are future Interstate-ish routes like I-69. Those Interstate routes may never be built, but since they’re identified it makes sense they have traffic and need Superchargers, right?
– I don’t tolerate much diversion, so for example I-35 from Ardmore to Perry, OK is listed because Oklahoma City, OK is over 10 miles diversion and I-55 is listed because of the relic of Tesla’s location desperation, Memphis, TN.
– I ignore urban Superchargers.
– Only a few of gaps listed have even identified splitter locations. Haubstadt, IN and Nevada, MO are under construction. Socorro, NM is identified.
– Watertown, SD to Fargo, ND is listed, and Watertown, SD fairly recently split a larger gap on I-29 from Sioux Falls, SD to Fargo, ND.
-Meridian, MS to Birmingham, AL is on an I-20/I-59 concurrency so listed twice

25* I-5 Grants Pass OR Springfield OR 138.4 Myrtle Creek OR 46.9 92.4

Aside: this is from a worksheet I have that goes down to 100 miles. That list has a total of 122 unsplit gaps. 9 gaps from my original list have been split (including some splits still greater than 100 miles), 8 are under construction and 3 have an identified (“permit”) location.

Updated: Asheville – Thetford St, NC is a pathetic splitter, so closes an entry but adds another one.

Updated: Striking through the open ones. Also added the important Myrtle Creek splitter which was just below the 140 in the original table.

Updated (3): Orangeburg, SC splits Asheville – Thetford St, NC and North Charleston. It’s only a partial splitter, and was a large gap, resulting in Asheville – Thetford St, NC to Orangeburg, SC (180.4 miles) being added to the list.

Updated: Tuscaloosa, AL open under construction and called Cottondale, to reflect the postal town.

Updated: Alice, TX splits (Future) I-69C from the start at Pharr, TX to the end at George West, TX

Updated: Sisseton, SD splits I-29 from Watertown, SD to Fargo, ND.
