Freeways without route numbers

[Katavia]

George W. Liles Parkway near Concord, NC. <-- Sort of
unnamed freeway near Chicago beginning at Lake-Cook Road
Any more?

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) 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.

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.

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.

Isn't that E-470?

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.

E-470 is different from Pena Boulevard.

unnamed freeway near Chicago beginning at Lake-Cook Road
Any more?

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.

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.

Sorry, those are very specific freeways, not random ones.  Choose much less carefully next time.

Puncheon Run Connector in Dover DE

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.)

Well, it does have a secret number, but Rochester's Inner Horseshoe (née Loop) has always been the archetype of random unnumbered freewayness.

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?

[cpzilliacus]

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.

Campus Dr in Madison, WI is a short un-numbered freeway.
