[Update] Six sites have opened, making 8 for the month and 207 total: Smelterville, ID (I-90 btwn. Enaville and Kellogg); Pueblo, CO (Jct. I-25/U.S. 50); Ft. Stockton, TX (I-10); Midland, TX (Jct. I-20/S.R. 158/349); Huber Heights, OH (I-70, just E. of Jct. I-75, N. of Dayton); Cocoa, FL Jct. (I-95/S.R. 520).
Smelterville shortens the I-90 leg between Spokane Valley and Missoula from 184 miles to legs of 56 and 130 miles.
Pueblo provides access to/from U.S. 50, E. or W, and shortens the (126 mile) I-25 leg between Fountain and Trinidad to legs of 35 and 92 miles.
With Ft. Stockton, it's just possible using extreme care to connect to Junction (201 mi.), and thus, assuming you have dest. charging at both ends, it's now possible (but not yet practical) to drive I-10 from Phoenix to Jacksonville. The "Coming soon" site" in Ozona, TX will shorten the Ft. Stockton to Junction leg from 201 miles to two legs of 102 and 93 miles. Other "Coming soon" sites needed to make the route practical are Hammond LA., Tallahassee FL, Tucson or Casa Grande AZ, plus a site in Lordsburg NM, Wilcox AZ, or somewhere in between.
Midland extends I-20 west from DFW, and it's now possible but not practical to reach Van Horn (183 miles), and continue on to Phoenix as above.
Opening Huber Heights means there is now a no-toll route (once you leave NYC via toll bridge or tunnel) from NYC to Chicago, via I-80 to Youngstown, then I-76 and 71 to Columbus, I-70 to Indianapolis and I-65 etc. to Chicago, although it adds about 124 miles to the trip; there's now also a no-toll route from NYC to STL and beyond. Two sites on I-70 in Pennsylvania are needed to provide a direct I-70 route to WDC/Baltimore.
Cocoa, FL, shortens the (149 mile) I-95 leg between Ormond Beach and Port St. Lucie to legs of 67 and 82 miles.
