Highway NOT entering your home state on which you have clinched the most mileage

[davewiecking]

Longest I've clinched is I-70, but it enters Maryland. I've traveled over 1600 miles of I-90, but that's barely over halfway to clinching it. It seems my answer is my clinch of I-66 at 76 miles, just beating out Iowa's I-380 at 73 miles.

Since I currently live in Nevada, the highway on which I have clinched the most mileage (non-current home-state category) would be I-70 (between its western terminus at I-15 and downtown St Louis--1352 miles) followed by I-5 between San Ysidro (San Diego) and I-90 in Seattle--1268 miles. Now, I actually used to live in the Denver area, hence I-70. I also lived in Portland for a couple of years and grew up in Orange County, CA (hence I-5).

In the never-home-state category, it's probably US 412 (including I-44) between the Hard Rock Hotel & Casino Tulsa & US 287 outside Boise City, OK (399 miles). Next might be US 191 from Helper to Bluff, UT (231 miles).

Mine is I-70, which I've poured 1317 miles into. By contrast, the highest US route (even counting those in Oklahoma) is US-40, which I've done 475 miles on. Kinda shows you what my travel priorities are...

I also have a nearly insurmountable gap between most traveled interstate (I-90, 1841 miles) and most traveled US route (US 52, 326 miles). Of course, I-90 does enter my home state, so my answer for this thread (I-94, 577 miles) is a lot closer, but still almost double the mileage.

That's a little more understandable in your case, though, since living in New York doesn't really lend itself well to long trips on US routes. I'm surrounded by lengthy US routes, like US-71, US-82, and US-160, I just...haven't used them much.

But how many of them are logical for long-distance trips? I imagine some are, like parts of US 69 and US 75, but others jump around enough that it seems more likely that mileage would accumulate in bits and pieces.
