The 2-lane stretch of I-93 through Franconia Notch, NH is about 5 miles long - it is divided by a double-faced guardrail in the median.

CA-37 between Vallejo and Sears Point, CA has a 9 mile stretch with 2 lanes separated by a concrete barrier.

The Mid-Cape Highway (US 6) east of Exit 9B in Dennis, MA is a super-2.  It was un-divided until some bad accidents in the 80s forced MassHighway's hand into installing a small median with reflective steaks.

The E4 north of Gävle in Sweden is divided for about 150 km, alternating between one and two lanes in each direction (2+1 road).

A contender is US 1 from the south end of Homestead at Card Sound Rd to Key Largo...

About 20 miles with a blue jersey wall and 2 lanes or 3 lanes total throughout except there is a 3/4 mile section about 5 miles south of Card Sound Rd where both sides have a passing lane.  There are a few intersections  where there are 4 lanes but one in at least one direction is a dedicated turn lane.

I'm pretty sure Europe (err, more specifically, Sweden) has us beat.

I thought of that one too. How long is it?

That stretch is 12.4 miles.

It may be one of only a handful of US Numbered Highways to go through every different roadway configuration.

I guess that is a divided highway in the technical sense.  Are U-turns regulated on that stretch?

No U-turns.  Passing was allowed prior to the median installation.

MD 90 is a divided super-2 from US 113 to the bridge to Ocean City (where it stops being a freeway).

Yeah, I was assuming Sweden would hold the record. I'm glad someone had actual numbers.

I remember that stretch going from Miami to my grandparents' house in The Keys, especially for the consecutive signs that said:  "Patience" "Pays" "Only" "3 Minutes" "To" "Passing" "Zone" (I see on GSV they've been replaced)

I remember there were signs that said that FHP monitors CB channel 9 as well along US 1.

What about MA-2's Super 2 length?  Probably shorter than US 6 on the Cape, though.

MassDOT did not retrofit a median on MA 2 west of the Athol Rd underpass, so for the purposes of this thread it's only about 6 miles.

Passing is still allowed on some of the Super-2 segments near Orange.

I remember those, so it couldn't have been that long ago, because it was maybe 2013 when I was down there.
On the way back, I got pulled over for passing. The guy in front of me was going like 10 under, but the cop said I just barely hit the double yellow on the way back in. No ticket though. And good for them: this is a really dangerous road. Coming back from Key West, there's a good chance that a few of the other drivers are drunk (I made sure to sober up before leaving).

I wouldn't call that stretch a controlled access highway as I seem to recall a couple of access points and one business.  Although I could be thinking of Card Sound Rd.
