unnamed freeway near Chicago beginning at Lake-Cook Road

I'm not sure what you mean by "random", but part of the Everett Turnpike in New Hampshire is unnumbered, as is the Lowell Connector in Massachusetts.
I think the Dayton (OH) Airport Access Road would qualify. It connects I-70 with the airport and has an exit for US40.
Does the freeway that connects to the airport in Denver have a number?
Seattle has two unnumbered freeways that are also not maintained by WSDOT:
The Airport Expressway connecting SR 518 to the Sea-Tac Airport is owned and operated by the Port of Seattle.
The West Seattle Freeway (which is officially signed as an extension of the West Seattle Bridge, per a city ordinance passed in 1997 (http://clerk.seattle.gov/~scripts/nph-brs.exe?s1=&s3=29541&s2=&s4=&Sect4=AND&l=20&Sect2=THESON&Sect3=PLURON&Sect5=RESNY&Sect6=HITOFF&d=RESF&p=1&u=%2F~public%2Fresny.htm&r=1&f=G)) is owned and operated by the Seattle Department of Transportation.
The Sam Jones Expressway in Indianapolis comes to mind. It used to be the route to the airport, but no longer serves that purpose.

Before your time the Spaulding Turnpike in NH was unnumbered as well, with 16 parallel to the east of it before being routed onto it about 25 years ago. I, however, struggle with whether it's a "random" roadway as well.
Are we talking about no number at all, or freeways that aren't
signed with a number?
Because if it's the latter, the Turnpike, Parkway, Atlantic City Expressway, would all count. Also, wouldn't all of the Kentucky Parkways count because they are signed by name and not number?
EDIT: I realize these are definitely not random, but considering the criteria specified by the OP... I would say they all count.

All of the parkways in New York are unnumbered. (The sort of exception is that the Henry Hudson Parkway has NY 9A routed along it for most of its length, but even it has an unnumbered part.) Also coming to mind are the JFK Expressway, the Central Scranton Expressway, and the Milford Parkway.

That would be a stretch of freeway between Dundee Road (IL-68) and Lake-Cook Road as IL-53 leaves the freeway at Dundee Road.
There's also a stretch of Lake Shore Drive between Hollywood and Foster. US-41 joins at Foster.
Then there's the small bit of Stony Island Avenue between 95th Street and I-94.
And, if you ask CDOT, the entire Chicago Skyway. IDOT and FHWA respectfully disagree.

How is this a freeway?

Many of the Parkways in the NYC area have reference numbers and are unsigned. Also CT 695, the Milford Connector (SR 798) and the stub of the Bradley Airport connector (SR 401). The Puncheon Run connector in Delaware is also unnumbered.

Add to NE2's list (which already includes an unnumbered freeway in Anchorage AK) part of the Johansen Expressway in Fairbanks. Last I was there in 2012, it was the only freeway in Alaska with exit numbers.
The Clinched Highway Mapping site shows many freeways, including in Canada, without route numbers. You can decide whether they are "random" or not, but it is clear from this discussion that they are thoroughly unexceptional.

No, Pena Blvd is not a state highway so it doesn't have a number. It's owned by the City of Denver and plowed by airport crews.

An older list now. The Elgin-O'Hare Expressway is now IL-390.
The only thing I can think of here is what I call the Willow Brook Connector in Berlin, CT. It's a bit over a mile long and runs immediately south of the New Britain city line. Technically it's unsigned CT Route 571. It opened in the early 1960s as an original alignment of the old CT Route 72. It has one exit (for CT Route 71). It mostly connects to CT Routes 71A and 372 on its west end and feeds into CT Route 9 on its east end. (It's left Exit 24 from CT Route 9 north.)

The freeway within DFW Airport is tolled.
Not sure if these would fit the definition of 'random', but both (part of) World Drive and Epcot Center Drive in Walt Disney World/Reedy Creek Improvement District are both freeways with no route number known to me.
Florida's Turnpike (SR 91) and the Homestead Extension (SR 821) are neither random nor unnumbered, but their numbers are not signed except sometimes on construction signs.
At first glance, the Veterans Parkway (the stub connecting I-516 to GA 204) and Harry Truman Parkway in Savannah, Georgia are freeways with no known route number.
Lake Pontchartrain Causeway and Causeway Blvd. in Mandeville before it becomes US 190?
The Dulles Airport Access Road (parallel to, but separate from Va. 267, the Dulles Toll Road) is "secret" Va. 90004.
The part of the Baltimore-Washington Parkway (BWP) that is owned and maintained by the National Park Service has no signed number, though Maryland has assigned it "secret" Md. 295.
Most of the George Washington Memorial Parkway (GWMP) is in Virginia, and is assigned "secret" Va. 90005.
The BWP has full access control, and even though it is a "true" parkway, the interchanges are not freeway-standard in terms of ramp widths and geometries.
Most of the GWMP north of National Airport has full access control, but there at least one place where a left turn across the median (and oncoming traffic) is legal, and there is at least one legal and marked bike and pedestrian crossing.

In Vancouver BC, Golden Ears Way (between 192 Street and Lougheed Highway) is a freeway. No route number (it's maintained by Translink, not the MOT). It has signals at either end of the main bridge, but there are plenty of ramps and divided junctions in between.

There's a freeway portion of the Tisdale Parkway in Tulsa.
Can the segment connecting I-290 to MA 85 be considered a freeway segment (as it definitely would be if it was part of I-290)?
Note: Google Maps is wrong; this segment actually is unnumbered.
I can think of several. None of these have any at-grade intersections, but most do not have exit numbers. I don't know where 'Parkway' fits; meaning is it closer to 'expressway' or 'freeway'?
Lincoln M. Alexander Pkwy, Red Hill Valley Pkwy, Don Valley Pkwy
Gardiner Exwy (no at-grades on this one either; entire length is above grade).
None of these have numbers I think because they are maintained by their respective cities, and not the MTO.
How about the Baltimore-Washington Parkway. I have been on it a few times and never noticed a route number.
The portion of that not maintained by the National Parks Service is MD Route 295.
Airport Connector in Harrisburg. It's a 4 digit SR, but PennDOT signs it on incredibly puny white signs.

Wade Avenue has an unposted secondary route designation too. As I posted in the "giving unnumbered freeways numbers" thread, I would prefer NC 54 follow I-40 to it and then follow it past I-440 and be extended east to US 70/NC 50 at Glenwood Ave.

You beat me to it. I'll add to that, Delta Highway is maintained by Lane County (or maybe the city of Eugene, but I think it's the county; Not ODOT). Beltine was originally also county maintained, although according to Wikipedia became a state highway in 1978. OR-569 was not signed until quite recently. I lived in Eugene from around 2003-2006, and it never was signed with a route number then. It is now signed as 569, although I assume locals still call it "The Beltline" or similar.

I still say that CDOT and the City of Denver should make it an extension of I-225 since to reach I-225 from Pena or vice-versa, you barely have a chance to take a breath on I-70 before you are exiting off for the other highway.

Almost every state maintained road in North Carolina has a "secondary route designation" though. If we started counting NC SRs as "numbered highways" then the only non-numbered highways would be roads maintained by private landowners.
Westside Parkway, Bakersfield, CA. When the Centennial Corridor project is comeplete, it will become a realigned CA-58 (or possibly I-40?) but for now, it's a 6-mile long local freeway maintained and patrolled by the City of Bakersfield.

Well, the Port Authority is a bi-state authority, but I'm not sure I take your point? NYSDOT numbers various roads maintained by counties and municipalities, and most of the Port Authority's other roadways do have numbers. I'm not seeing the connection between the jurisdictional level of an agency and whether or not its roadways have numbers.

Regarding Storrow Drive, you're right. But don't believe Google Maps or the locals about it. East of the "Copley Square" exit, the road carries Mass. Route 28 and turns northeast, but is actually (almost secretly) named Embankment Road. Depending on who you ask, once you pass the Longfellow Bridge it's actually Charles Street, which carries not only 28 but Mass. 3 as well.
Edit: After that convoluted explanation, I forgot to include the important point that the proverbial "everyone" calls all of it "Storrow Drive" even though, strictly speaking, those numbered portions are not.

Comes down to a matter of opinion. If you drive along the whole length of a freeway, with only a name to reference to the road, it's basically unsigned; it has no obvious route number. This "list" should consist of freeways that either have no route number, or are unsigned.
