Three sites have opened, making 33 for the month and 232 total: Richfield, UT (I-70); Charlotte, NC (Jct. I-85/S.R. 24); New Castle, DE (S.R. 13, 3 Mi. S. of I-495).
Richfield is needed to allow travel along I-70 btwn. I-15 and Grand Junction, but at least one more site, probably in Green River or Crescent Junction, UT, is needed to make the trip possible let alone practical, as it's 225 miles between Richfield and Grand Jct. Richfield connects to Beaver, Scipio and Spanish Fork.
Charlotte provides connections to EA QCs all around it on I-40/74//77/81/85/95.
New Castle appears to be for bypassing downtown Wilmington on I-95.
220 or so highway sites are open out of the 300 Hwy sites which were required to be open or substantially underway by today. Out of the 232 total that are open, some, perhaps 6 -12, have been urban sites, which weren't part of the 300 highway sites required by today.
