Your first clinch?

[LM117]

As a passenger

Interstate: I-280 in Toledo, OH

US Route: If business routes count, Business US-70 and Business US-117, both in Goldsboro, NC

State Route: Jackshit

As a driver

Interstate: I-795 in NC (the freeway was initially signed as US-117 when I drove it for the first time in 2006. Drove it many times since it became I-795. I was living in Fremont at the time, so clinching it was easy peasy  )

US Route: Business US-117 and Business US-70, both in Goldsboro, NC (I can't remember which one I clinched first, but they're near each other.)

State Route: Former NC-44 (now signed US-70 Bypass) in Goldsboro, NC (clinched in 2013 while it was only open from I-795 to Wayne Memorial Drive sooo....success!  )

Just counting as a driver, since who the hell knows what I did as a passenger

State: Washington 163
2dus.: U.S. 730
3dus: U.S. 16
2di: I-82
3di: I-184

[hbelkins]

Either KY 498 (Lee County) or KY 1571 (Estill County), one of them most likely as a newborn on my way back home from being born in a Lexington hospital. Depends on what route my dad used driving back home from Lexington.

In New South Wales:
A28 was the first route I clinched.

[roadman]

As a passenger with my dad in 1971, my first clinched state route was MA Route 128.  Shortly thereafter, my first clinched Interstate route was I-93 in Massachusetts - this was before it was extended through Boston down to Canton.

As a driver, my first clinched state route (in 1979 just after I got my license) was MA Route 107 , and my first clinched Interstate route (in 1983) was I-90/MassPike from Boston to West Stockbridge - was on a trip with my parents, and I had driving duty for the first leg to Albany.

Since that time, largely due to my work, I have managed to clinch every Interstate and freeway in Massachusetts - including every exit and entrance ramp.

Did your age just jump from 15 to 16?  If that's the case grab the car and go clinch a route to celebrate...assuming you have your license.

I will be getting my permit on August 6...so I'm excited! 

[Takumi]

Can't remember offhand anything as a passenger. I know for sure I have no US or 2-digit interstate clinches. As a driver:
Interstate: I-295 (VA)
State: VA/NC 168

[1995hoo]

If we're limiting it to two-digit Interstates, then I think as a passenger it would be I-66 and as a driver, surprisingly to me, I think it'd be I-85.

[cl94]

If we're limiting it to two-digit Interstates, then I think as a passenger it would be I-66 and as a driver, surprisingly to me, I think it'd be I-85.

For 2DIs, probably I-88 in New York, both as a passenger and a driver (over a decade later). Very easy 2DI clinch because there is nothing between the endpoints.

It's also the only 2di that I've clinched.

I-93 (MA, NH, VT) / I-495 (MA)
US 4 (NY, MA, NH)
MA/VT 142

[Roadsguy]

So far with my learner's permit, I've fully clinched two routes, though I'm not sure which is my first: PA 581 and PA 343. Arguably I didn't truly clinch 581 because I got off and back on at US 11 in Mechanicsburg. The 343 clinch was also in two parts: most of it from Maple St. north, and the last little piece on Maple St.

[TheHighwayMan3561]

Solely as driver:

2di: Eastern I-88
3di: I-277 (OH)
US: 61
State: MN 101 (Rogers-Elk River)

[Rothman]

First 2di's a tough one.  I really doubt it was I-84; I don't think I ever was on the section east of I-91 when I-86 was still around in CT.  Even when I-86 became I-84, it wasn't until much later that I drove the old I-86 section, since I never had a reason to given where I lived.

Best guess is I-91.

[dgolub]

My first clinch was almost undoubtedly NY 101, probably dating back to before I could even talk.  It's only a few miles long and leads into the town where I grew up.  My first county route clinch was Nassau CR 15, which is also in the town where I grew up, although I didn't know its designation until senior year of high school because Nassau County doesn't sign county route numbers and doesn't like to even admit that they exist.  My first interstate clinch was probably the Throgs Neck Expressway (I-695), which you clinch if you're approaching the Throgs Neck Bridge (I-295) from the north.  My first and only two-digit interstate clinch so far is I-84.  No US routes yet, unless I'm missing something.

[slorydn1]

If limited to 2di then first clinch would be eastern I-76 (as a baby).

[Walleye2013]

My first clinch while driving was Interstate 480N, which was during my first driving on a freeway. If we count signed routes, it would be Interstate 271. The first I clinched in one go was Interstate 290 in Massachusetts.

[mefailenglish]

As a driver:
2DI:  I-97
3DI:  I-695 (Baltimore)
US:  340
State Route:  MD 404, three weeks after I got my license

[cpzilliacus]

Riding (pre-licensed age), probably I-70S (now I-270) in Maryland.

Driving, probably I-495 in Maryland, Virginia and a tiny slice of the District of Columbia.

[PHLBOS]

MA 22 (by bike)

MA 25 (as a passenger), prior to it being extended east to the Bourne Bridge and taken over by I-495 (between MA 24 & I-195).

MA 128 (as a driver, including I-93 & 95 sections)

[paulthemapguy]

First accidental clinch might have been I-190 (Illinois), which is a glorified driveway.  Or Illinois 126.
First intentional clinch was Illinois 21, just two months ago 
The first 2di I've ridden the entirety of was probably I-76 (Colorado) when I was 12.  The first 2di I clinched with myself behind the wheel was either I-88 (Illinois) or I-57.  I don't think I've clinched any US routes yet, but I plan on clinching my first when I drive down to the Gulf Coast within the next 2 months (US43).
