For my submission...Here is this road in Mexico.

GSV along it and you'll see some vehicles that really struggle to fit in.
The Aurora Bridge in Seattle crams 6 lanes into 57 feet of deck space, making for some very narrow lanes. Buses and trucks have to straddle the outer two, and there's no room for a proper barrier (leading to several cross-over crashes).

Any Mass Pike exit ramp.
Since the OP started off with a Mexican road, here is one (https://www.google.es/maps/@42.1405097,-0.4540165,3a,75y,317.93h,91.89t/data=!3m6!1e1!3m4!1sIjdhYlX7RsLrzmBTKVXdQg!2e0!7i13312!8i6656) I regularly drive.

No. If anything, the ramp from I-90 EB to I-91/US 5 is overly wide, just as one example.
Nothing narrow about the ramps at Exit 2...at MA 32...
Maybe within I-95, but definitely not enough to say they're all narrow.

A true nail-biter for first time drivers!
The narrowest significant road that comes to mind off the top of my head is the old, now-demolished, Goethals Bridge, as well as the Outerbridge Crossing (https://goo.gl/maps/9XrfeScyBTHLjFyE8). Off the top of my head, I'm not sure whether I've ever driven over the Outerbridge myself (as opposed to riding over it as a passenger, which I have done umpteen times), but I certainly drove over the old Goethals Bridge. The 10-foot-wide lanes made for a very unpleasant drive if there were large trucks around.

Alewife Brook Parkway -- MA 16's another good one.
MA 6A/28 in Orleans. US-6 in Eastham used to be just as narrow until a 1982 widening project.
The Nacimiento Ferguson Road near CA 1 has a really narrow two lane for some reason. I think it is meant to be a passing zone on the first climb/final descent from/to the coast:

Back before AL 35 was 4 laned southeast of Scottsboro, AL, it was a 2 lane and that old bridge was a true nail biter before the road was twinned.
If we're counting bridges, The Hood River Bridge across the Columbia between OR and WA comes to mind. Lanes are 9 ft 4.75 in according to their website. I drive it a few times a year, certainly not a walk in the park, though I've never had an issue with it.

The Grace Bridge (old US 17) over the Cooper River in Charleston. Used to be one lane each way until the 1966 Pearman Bridge opening. With like 9-10' lanes. And big trucks crossing all the time.

True, but look at the right lane in my example. I know it's probably just the bridge/guardrail, but that does not look 10' to me.

So, every single time a chunk of concrete crumbles off the Jersey barrier, does it cause vehicle damage? I don't see much opportunity to swerve around it.
Here's one in Philly. There aren't trucks, which is good. But this is darn narrow going northbound (right side of street view) since the last repaving and restriping.

Also the access road form US-60 to Mud River Baptist Church in Barboursville, WV, which has 9' lanes.
9-foot lanes are relatively common across WV's route network, even on some primary roads.
The Burlington—Bristol Bridge (https://goo.gl/maps/BJhdpVbXd174nHVS7) (which carries PA/NJ 413 over the Delaware River) is pretty narrow. Until a repave about 5-6 years ago, it was only striped with a single yellow line.

Absolutely not... I frequently go down Front Street and get pretty uncomfortable if I'm in the center lane. The curve at Liberty Street and the dip in front of UPMC is straight up dangerous if traffic is heavy. It gets even worse on the north end of the city when it becomes two lanes each way undivided.
I'd rather break down in Allison Hill than take Front Street during rush hour!

Both of those bridges have 20-foot decks, FYI.
Lumpkin Street in Athens, GA used to have four 7' lanes with no median or center turning lane from downtown to Five Points. Buses couldn't even fit into a single lane. Athens-Clarke County has reconstructed it since then, and now it has two 10' lanes with two bike lanes and a center turning lane -- and they had to widen it to do so.

A true nail-biter for first time drivers!
You didn't even mention the scariest part: they used to be reversible lanes! Engine driving on one of those bridges with oncoming traffic!
Also, I'm pretty sure most older tunnels could qualify for this thread.

Lumpkin Street in Athens, GA used to have four 7' lanes with no median or center turning lane from downtown to Five Points. Buses couldn't even fit into a single lane. Athens-Clarke County has reconstructed it since then, and now it has two 10' lanes with two bike lanes and a center turning lane -- and they had to widen it to do so.
Any idea if there are pictures of this old setup? Looks like the conversion took place in the mid-2000s, and isn't on Street View.
7' lanes seem wicked narrow for an urban setup. Farm road? Sure, but even urban roads typically bottom out around 8' or so. 7' is nuts.
