Which Interstate has the most number of realignment changes? An example of which is like I-40 through Winston-Salem being rerouted to the south. I-85 moving from what is now I-85 BL in both SC and NC in different segments.
AFAIK I-95 has had three realignments due to cancellations and wasn't continuous until 2018. In addition it was realigned out and back in Wilmington DE due to some reconstruction project.

Add the 95/295 switch in Maine.
Some for I-70:
- Before the Stan Musial Bridge was completed in St Louis in 2014, it used the PSB along with I-55/I-64/US 40.
- The mainline highway used to make a loop through downtown Pittsburgh via current I-79, I-376 and I-76, and the Washington-New Stanton section was I-70S. The mainline was moved to I-70S later on.
- East of Frederick, I-70 split into two suffixed routes: I-70N to Baltimore and I-70S to DC. I-70S was later changed to an extended I-270 (I-270 used to be just today's I-270 Spur) when the section south of I-495 got cancelled, and I-70N to simply I-70. Depending on how you interpret suffixed interstates, you can either interpret this as I-70 getting extended east a bit, or I-70 losing the DC branch.

Probably Evansville for a while until the new Ohio River crossing gets finished.

I hope they leave this as a Breezewood situation or Henderson will become a ghost town.

There is quite a bit of local traffic that will continue to use the "free bridge".
Also with I-69, it was extended in Michigan. I think that it either ended in Lansing or Flint at one time (I'm thinking Lansing) before going over to Port Huron.

I-69 first ended at I-94 in southern Michigan. AASHTO then approved the extension to end at I-475 in Flint in 1974 (though it was the early 90s before this stretch was 100% complete). The AASHTO approval to extend the freeway to Port Huron happened in 1983.
I-40 has some other ones too:
Oklahoma City- realignment SW of downtown. Is it OK City Blvd?
Memphis: if you count I-40 along Sam Cooper Blvd before the cancellation through Overton Park and putting 40 on the loop.
iPhone
In the not-so-distant future, I-74 will have two: Winston-Salem beltway and Mississippi River bridge (it's iffy, but if OKC Blvd can count, I don't see why this wouldn't).
It also has numerous extensions over the course of its history, but I don't think that counts.
Interstate 76 was designated on the PA Turnpike in 1964. Within a few years, the Laurel Hill bypass and the Rays Hill/Sideling Hill bypass were completed. Much later, a couple short realignments* were constructed just east of the Allegheny Mountain Tunnel and one just east of the Blue Mountain Tunnel.
In addition, in 1970, I-76 switched alignments onto the PA Turnpike and into Ohio, having originally ended in downtown Pittsburgh and joining the PA Turnpike in Monroeville ( the route downtown is now I-376). Also, I-76 and I-676 swapped in 1972.
A bypass of the Allegheny Mountain Tunnel has long been proposed but still remains in the planning stages.
*These realignments may be considered rather short for the purposes of this exercise, but with no exact criteria given (such as length of the new roadway, distance from the old alignment, etc.) they are listed here.

And alongside one of those former I-85 segments in North Carolina, you had I-40 moved off of Death Valley after the opening of the Greensboro Bypass only to be placed back on its original routing after some of the reconstruction (and the approval of I-73 on the northern end of US-220 corridor). Local media always said that the switchback was due to pressure from Greensboro City Council, but I suspect that NCDOT wanted to get full 2dI status on both of those freeways.
I can think of three (with a fourth possibly in the future) for I-85. And possibly a fifth (open to interpretation).
- Greensboro, NC - it used to go through downtown on what is now BL I-85
- Spartanburg, SC - ditto
- Atlanta, GA (northeast) - used to be routed on GA 13
Sometime (who knows when):
- Montgomery, AL - when (if?) the southern bypass is constructed, I-85 will follow that; the part through Montgomery will become I-685.
And a possible second one for Atlanta (southwest), but open to interpretation:
- Prior to 1980 or so when that segment of I-285 was massively reconfigured, I believe I-85 was concurrent with I-285 for a bit before branching off towards downtown Atlanta. Nowadays, I-85 runs between the carriageways of I-285, but technically isn't concurrent.
