What do you consider "clinched"?

[intelati49]

I feel the same way, minus the age 7 part. As long as I can remember being on all of it (even in parts), it counts for me. It does not have to be both ways (even though there are a couple roads that count as clinched for me in that sense), though it does need to be consistent in direction. (E.G. I would not consider taking I-70 westbound from Baltimore to Topeka and eastbound from I-15 to Topeka as being clinched.)

We differ on the last part. I consider routes clinched by taking the full route with no distinction made as to what direction it has been done in. My I-71 example comes to mind. I've done both sides of 71 from Louisville to as far as Mansfield...but only southbound north of that point. I still consider it clinched because I have been ON 71 from Cleveland to Louisville.

US71 ["I-49 MO clinched"] for me is kind of like that... I have never taken it from Bella Vista to KC, but I have driven every mile of pavement NB/SB in several trips. NB to Joplin (MO249), SB to Bella Vista (US71), SB to Neosho (MO59) NB to KC (MO59), then EB/WB to and from Springfield/Carthage
