Freeways without route numbers?

[coldshoulder]

Physically, a very short section where I-76 and I-80 bump in Ohio, which is entirely unnamed. Also a short section of the Ohio Turnpike in that same place if it doesn't have a secret number. Even though per the log I-76 and I-80 change roadways where they cross, I consider a wrong-way concurrency to exist through the toll booths.

If you're referring to the double trumpet that serves as the entrance/exit connector (thru the toll booths) between the Turnpike and I-76 west and I-80 east, then you'd have to consider thousands of those same type structures across the country/world.     I don't think the OP had this in mind.

If you're referring to the southerly extension of that trumpet to Mahoning Avenue (CR-18) utilizing the original interchange with the Turnpike, that's not a freeway by any stretch of the imagination; it's nothing more than a glorified connecting exit/entrance ramp, with a posted speed limit of 35 mph--certainly not a freeway.

For somebody traveling in either direction on Mahoning Avenue/CR-18, the connection only allows access to the Turnpike (I-80 west, and I-76 east), and doesn't permit one to access I-80 east, or I-76 west.  Likewise, somebody traveling on I-80 west or I-76 east *prior to the Turnpike* cannot access this connector to get to Mahoning Ave.

So to summarize: it's a short section of road, with a reduced speed limit, one lane in each direction separated only by a foot-high or less concrete median, and provides only a connection to and from the Turnpike, and not the other major east-west freeway at that interchange = NOT a freeway.

The road leading up to the terminal of the Kansas City Airport (Cookingham Drive west of I-29) is a freeway. It has three interchanges, but has one at-grade intersection (I won't count it, because it is restricted access).

In Illinois, the Ohio-Ontario Feeder, the Congress Extension of the Eisenhower Expressway, the Stoney Island Feeder and the Chinatown Feeder in Chicago are all un-numbered.

In Madison, WI, Campus Dr is un-numbered.

I'm surprised no one has mentioned Sam Cooper Blvd in Memphis. It was meant to become part of I-40 and was partially built but locals blocked building it through the Memphis Zoo.

To my knowledge, it has no numerical designation.

[-- US 175 --]

James White Parkway in Knoxville south of when TN-158 leaves the route and Sam Cooper Boulevard in Memphis are Tennessee's only unsigned freeways.

Mentioned on the previous page.

I don't believe Minnesota has any today. Before 2008 there was a short unnamed/unnumbered freeway section connecting I-494 to US 212, before 212 was routed onto this section when the new 212 freeway was completed.

[Flint1979]

... has been M-8 for about 25 years.

M-8 was designated about 1993, but not posted until 1997 when the rebuild was complete.

Yeah I'm pretty sure it became MDOT maintained just to get the rebuild done. The pavement hadn't been replaced up to that point since it became a freeway in the early 1940's. Only becoming a freeway as a quick way to get across Highland Park, now it could actually be a street again and do just fine.

Adirondack Northway south of the Thruway.

And the portion of the Thruway mainline through the 24 interchange where 87 leaves and 90 joins north/westbound, and vice versa south/eastbound. And, the Berkshire Spur west of B1.  Yes, I know there are NYS Reference Route numbers, but they're not officially signed with numbers.

Alfred Harrell Highway in Bakersfield.  Minnesota Drive in Anchorage. Wayne Gretzky Drive in Edmonton.

There is one north of Alliance, Ohio that was intended to carry US-62 eastward towards Salem, Ohio, where it was supposed to multiplex with OH-14 for a stretch.

The portion near Alliance is shown on Google Maps as 62-T (Temporary) but is not signed, except for a few signs that read "To 225", an Ohio north/south route where the freeways ends.

The shorter portion north of Salem is shown on Google Maps as 14-T (Temporary) on its western stretch, and US-62 on a short eastern stretch.

The old section of the Elgin-O'hare Expressway in IL used to have no number when IDOT controlled it. When ISTHA took it over and actually extended it to O'hare and instituted tolling, it became the IL 390 Elgin-O'hare Tollway, so now it is numbered

If things like the Ohio Street and Chinatown Feeders in Downtown Chicago are listed, so would be the University Ave Feeder into Champaign from the I-72/I-74 Cloverleaf

[nexus73]

Delta Highway in Eugene is a freeway from I-105 to Beltline Road (SR 569) that has no number.

A number of turnpikes in Oklahoma have no route numbers as far as I know: the Chickasaw, Kilpatrick, and Indian Nation, plus the Cimarron and HE Bailey Norman Spurs.

CA-275 West Sacramento has a freeway ramp stub for US-50 but that is unsigned and is known more as Tower Bridge Gateway and Capital Mall.

Hidden CA-244 Sacramento is not a numbered route.

There is, however, a freeway that doesn't even have a reference route number - the JFK Expressway.  Even the Central Westchester Parkway is unsigned Westchester CR 150 (the county portion of the Bronx River Parkway doesn't appear to have a number, but has a ton of at-grades).

CA-275 West Sacramento has a freeway ramp stub for US-50 but that is unsigned and is known more as Tower Bridge Gateway and Capital Mall.

Hidden CA-244 Sacramento is not a numbered route.

244 has some post mile paddles that reveal the route number.

A new-but-old unnumbered freeway segment:

Former Interstate 70 east of I-695 in Baltimore, MD

[ilpt4u]

I'm shocked no one has mentioned Ontario's Queen Elizabeth Way

A new-but-old unnumbered freeway segment:

Former Interstate 70 east of I-695 in Baltimore, MD

Isn't that part of US 40? Or is that a segment of a different cancelled Baltimore Freeway?

A new-but-old unnumbered freeway segment:

Former Interstate 70 east of I-695 in Baltimore, MD

Still part of I-70. It was authorized for removal from I-70 to make way for a new transit facility. However, that facility got canceled, so the removal got canceled too.

Delta Highway in Eugene is a freeway from I-105 to Beltline Road (SR 569) that has no number.

Not for long. Lane County is in the process of transferring jurisdiction to ODOT, and when that's complete the Delta Highway will be OR 132.

Illinois
The furthest-north section of the IL 53 freeway, from Dundee Rd to Lake Cook Rd, has no number.  IL 53 exits at Dundee Rd. and has as long as I can remember (mid 1970s).  Google Maps shows that leg to be IL 53, but other sources say it's still unsigned.

While it might technically not have a number, it's mostly signed at Lake Cook Road as IL 53.
Eastbound Lake Cook
WB Lake Cook
WB Lake Cook gore assembly

At IL 68 it's signed without the number

There's also the numberless freeway segment of Palatine Road not too far away.


In the St. Louis area there's the freeway segment of Forest Park Parkway through Clayton.

The Elgin-O'Hare was going to be signed as IL 19 before it opened, which would have removed that number from Irving Park Rd.  Signs had already been erected on the E-OH and were visible at the intersection of Rohlwing Rd. and Thorndale Ave. while the finishing touches were being put on the freeway. The cities and villages along Irving protested, and those signs were removed before the road opened. 

If things like the Ohio Street and Chinatown Feeders in Downtown Chicago are listed...

IIRC, the Ohio St. feeder was supposed to be part of the never-built Crosstown Expressway, which had been given I-494.

At IL 68 it's signed without the number

The off ramp from northbound 53 to Dundee Rd. shows Dundee westbound signed as IL 53 & 68, just as it has for at least 40 years.  Google maps labels the "last mile" (or, first mile if going south.  ) between Dundee and Lake Cook Rds as "IL 53 Spur."

The end of the line, at Lake Cook Rd.

There's also the numberless freeway segment of Palatine Road not too far away.

That's not a freeway.  It's a limited-access expressway, but has several at-grade intersections at major streets.  Again, the same as it was when I lived in Palatine in the early 1980s.  AFAIK, it has never been assigned a number.

[Thing 342]

A few that have absolutely no number, to my knowledge (this includes hidden / unsigned designations):

- Minnesota Dr. freeway in Anchorage, AK
- Veterans Pkwy in Savannah, GA
- Harry S Truman Pkwy in Savannah, GA
- Sugarloaf Pkwy (east of GA-20) in Lawrenceville, GA
- Puncheon Run Connector in Dover, DE
- La Jolla Pkwy in La Jolla, CA

A couple more dubious examples:

- The Intermodal Connector in Norfolk, VA (partial interchange at I-564, incomplete interchange at other end with VA-337)
- The A/C St. expressway in Anchorage, AK (includes a full T interchange with the entrance to the Port of Anchorage, but could be considered a bridge approach)
- Busch Gardens Blvd in Williamsburg, VA (short and more of an entranceway, but completely grade-separated and with full interchanges at US-60 and I-64)
