Technically, Future I-587 is longer than North Carolina's I-87, but I-587 hasn't been signed yet, and I-87 hasn't been completed to the Hampton Roads area. Count it if you want to.

I-587 doesn't exist yet. I-87 exists for 13 miles.

This will change, however, once the portion of US-264 east of I-95 is designated.

I -269 than the segment in TN being it's not even signed. However I-269 is longer than I-69 where it connects near Hernando, MS.
