It doesn’t deserve a two digit number. As a bypass, it should have a three digit number. Keeping 515 would have been OK, although it should start with an even number. Or, better yet, give it a federal highway designation. Calling it Interstate 11 is also wrong since it is east of I-15. Sounds like it was all just a scam to fleece the taxpayers.
When complete, I-11 will begin at Tucson, bypass Phoenix to the south and west, take over US-93 to where the current I-11 picks up, take over US-95 to Reno, then take over US-395 all the way to the Canadian border. It’s intended to be primarily a truck route.
Actually, this is only the first part of Interstate 11, which is eventually going to connect LV and Phoenix, and then maybe run all the way from Canada to Mexico.
But if it is slated for Reno, it will end up far west of i-15.
In the east, the i-99 corridor between Williamsburg, PA and Corning, NY is between i-79 and i-81.
