Not quite sure what you're doing here but if it's what I think it is then PA 3 is a surface road its entire length.

I think it's "lowest number not used for a freeway anywhere in the U.S." So MA 3 takes care of 3, everywhere, without getting into other freeways also numbered 3 (like parts of US 3).
US 34, a few miles of which is freeway in Galesburg IL, takes care of that number. But there is no US 38, 102, 103, and 106, US 48 in WV has interchanges but enough at-grades to disqualify it as a "freeway", and IIRC US 98 has no freeway segments, so for those numbers we'd need to look at state routes.
SR 38 in Alabama (which overlaps with US 280) probably disqualifies 38 as lowest number if we are considering unsigned routes. Are we?

If that doesn't do it, IA 38 (concurrent with I-80 for a few miles) should do the trick.
Washington State Route 4 is single carriageway throughout its length between the 5 and 101.
US 23's freeway status around Upper Sandusky, Marion, that whole area is kind of shaky. But in the Toledo area and north into Michigan, it's undisputable.
If I understand the topic correctly, I'll nominate Florida State Road 2.
For those suggesting numbers below 10: Those numbers are used for freeways in other places. It's "lowest number not used for a freeway", NOT "lowest-numbered road that is not a freeway".
I think I got it: Somewhere in the United States, Route 1 thru Route 47 is a freeway at least somewhere. For example: DE 1, I-2, MA 3, I-4, I-5, US 6, etc., are all freeways. Thus, we are trying to list a route number that has not been mentioned yet that *IS* a freeway somewhere within the country. And then based on that list, we'll figure out what the lowest number is that never is a freeway.
So currently, based on the list above, Route 48 is not a freeway anywhere in the country as far as we know.

If we are looking for none cosigned routes, IL 38 Roosevelt Rd is officially a freeway between Route 83 and I-294.
If that doesn't do it, IA 38 (concurrent with I-80 for a few miles) should do the trick.

You might have nailed it. However, according to the ever-reliable Wikipedia, some sections of US 48 in WV will soon be, or are being, upgraded to freeway status. I can't confirm that on any mapping site, though.
US 98 has a freeway segment on the south side of Hattiesburg, MS. Barring that, the OP used Interstate concurrencies as justification, and US 98 has concurrencies with I-55 and I-59.

I'm surprised you missed Mass. Route 2, which is a freeway for dozens of miles.
He automatically skipped all numbers that are an interstate.
CA-103 is, for the time being, the Terminal Island Freeway.
The southernmost 65 miles of CA 14 are freeway. And a very busy one at that.

At least you said US only, because I would came up with A-48 expressway in Southern Spain :sombrero:.
Illinois 1 has some multilane sections but none are freeway. However it was proposed as a supplemental Freeway before Indiana made US 41 an expressway.
But to your point IL 2 and IL 5 have both been mostly or partly replaced by I-88,which was originally IL 5 . Even though some of the low number Illinois routes became freeways. they were the original rote numbers for the sate road bond issues. US 67 was SBI 3 for instance
CONN 9 is a freeway for much of it's length (aside from that short stretch in Middletown).....However, i dont think CONN 4 is a freeway at any point of it's run

Conn 4 may not be a freeway, but 4 is an Interstate, so that number is out.
Has AZ-48 been designated along Fain Rd in Prescott yet? (and if so, does that count as a freeway?)
Would the FL-102 connector to the Jacksonville Airport count as a freeway?
Does it have to be signed? Because if not, then AL 2 might count as it doesn't even touch a freeway (other then the very eastern end of I-565 and where it crosses over I-65).
You are mostly dumbfucks.

No. Neither does US 48 (despite WVDOT calling it one on signs). But the older US 48 was a freeway.

Doesn't matter though, because I-2 is a freeway, so the number 2 is already covered. The lowest number we need to even consider is 48, followed by 102, if I'm keeping track correctly.
I think it might be 48.
OK-102 overlaps with I-40 for a couple miles near Shawnee: http://goo.gl/maps/CInyN

TX-48 is fully grade separated between Vermillion Rd and Cantu Rd outside of Brownsville, a distance of 2.4 miles. Does that count?

Looks like just two closely-spaced interchanges, on a highway with lots of at-grade crossings west and east of those interchanges. My personal rule of thumb is that you need at least three interchanges, with no intervening at-grades, to be a "freeway".
IMO, borderline at best.

Though if this were the lowest number never used for a freeway, 48 would fail. IIRC (I have a bad habit of like half-remembering historical trivia), the current US 48 is the third one; the second one is now I-68. Presumably some or all of it was freeway before black and white signs were replaced with red and blue ones.

Correct. The "National Freeway" was constructed in segments as a full freeway and signed as US 48. It wasn't until completion (or thereabouts) that it became I-68.

you're right, it says "expressway" and "controlled-access" - which i misinterpreted as "freeway."

"Controlled-access" usually means "freeway" ("expressway", not necessarily). But while US 48 has interchanges here and there, it has no sections where there are multiple interchanges
and no at-grade intersections between them, so there is nothing consistently freeway-grade.
US 48 has a "Freeway Ends 1 Mile" sign (https://www.aaroads.com/forum/index.php?topic=1665.msg2023999#msg2023999) near its current western end. However, that sign immediately follows an at-grade intersection. True, that one-mile "freeway" section has an overpass, and an interchange at its west end, but IMO that doesn't make it a "freeway" by any reasonable definition. I don't think the next phase of construction, extending US 48 further west, will change that situation, since AIUI there will be no new interchanges added before the highway reconnects with WV 93 at an at-grade intersection west of the Mt. Storm power plant.
