This begins a series of blog posts outlining ideas I had to expand the Interstate Highway System, which will involve some renumbering of existing routes to get rid of the oddities that have emerged over time (like I-24 and I-26 being largely North/South routes), and to facilitate expansion of the system.

Here’s a new route to get us started:

 Intestate 28 - Decatur, Alabama (I-65) to Bolton, North Carolina (Future I-20)

 This route would begin by replacing Alabama’s I-565 in its entirety.  I-28 would then follow US 72 from Huntsville, Alabama to I-24 near New Hope, Tennessee.  From there I-28 would overtake I-24 through the Chattanooga area to South Cleveland, Tennessee.  I-28 would then follow or replace US 74 all the way to Rockingham, North Carolina.  Through Gastonia and part of Charlotte, I-28 would overlap with I-85.  East of Rockingham, I-28 would replace an already planned expansion of I-74 in North Carolina, which consists primarily of upgrades to US 74.  I-28 would end at Bolton, where a planned extension of I-20 would carry traffic headed to Wilmington.
