In Florida where I live I have gotten to ever cross state ending in zero except SR 20 west of US 331.
I’ve gotten all US routes except for two segments of US 331.
I’ve done all interstates but parts of I-95 in Palm Beach, Broward, and Miami-Dade counties.
In Texas I’ve gotten all of I-35, but missing parts of I-35E and I-35W.
All of both I-37 and 45 in the Lone Star State including I-610 and I-369. Oh yes, I forgot I’ve clinched I-30 in two separate trips..
For now I’ve gotten all what is signed of I-14 there.
In Colorado I’ve clinched all of I-25, but need from Denver to Limon to complete I-70 there plus need both I-76 and 225.
In Kansas got all interstates done except I-435 on the west side of KC. Most of US 54 I’ve tackled but need east of US 169 and from Minneola to Mullinville to finish.
I’ve got more but those are for now.
