3di's that are longer than their state's portion of the associated 2di

[CNGL-Leudimin]

In fact all branches of US 95 are longer than US 95 itself in Washington (the latter now doesn't enter at all ). This also applies to former US 295.

Non-zero example: I-155 in Tennessee

I-55 runs in TN.  It runs from AR to MS.  It runs 12.6 miles.  It is shorter then the 15.9 miles of I-155 in TN though.  So it still works but is not a 0 example.

That's what non-zero means.
