Do the split segments of I-74 in North Carolina count separately? If so, then the one from Lumberton to Laurinburg is mine, otherwise I have never completely clinched an entire 2di. I've come very close on I-4 (only missing from I-275 to I-75) and I-71 (only missing the last 2-3 miles in Cleveland).

I highly suspect that the OP intended that the entire route be clinched in a single trip.  My list meant to be tongue-in-cheek.  But yes, I was treating each independent section as a 2di clinch.  Then when the route got extended, it was unclinched.  And just in case you noticed another mistake, I actually did reclinch I-74 from North Asheboro to Winston-Salem.

For the record, I haven't clinched many 2DIs on a single trip.  Here's my list:

I-16 from Savannah to Macon (twice)
I-4 from Daytona to I-275 Tampa (didn't think I had clinched this, but went to drive the new Sunshine Skyway when it first opened in 1987.  First real proof that I was a die-hard roadgeek).
I-68 from Morgantown to Hancock (at least 100 times)
I-83 from Harrisburg to Baltimore (once, did this on purpose to clinch the north end)
I-97 from Baltimore to Annapolis (twice)
Sorry, but:  The other I-87 from Raleigh to East Knightdale (twice, wasn't trying to clinch, just needed to avoid traffic on I-40) (and twice as I-495, plus many times before that)

Almost, but not quite:  I-96 from Brighton to Muskegon (twice, both ways same trip)
Almost, but not quite:  I-78 from Harrisburg to Newark (numerous different exits, furthest east would have been I-95).

Which brings me back to parody land:  I-78 disconnected segment through the Holland Tunnel (four or five times)
