Freeways without route numbers?

[sprjus4]

^

Kentucky's parkways have internal route numbers, but they aren't signed.

[sbeaver44]

Also isn't the Chicago Skyway *technically* not part of I 90?

Wikipedia does a decent job explaining that conundrum.  I consider it I-90.

"However, around 1999, the City of Chicago realized they had never received official approval to designate the Skyway as I-90. The city subsequently replaced most of the "I-90" signage with "TO I-90/I-94" signage. However, the Illinois Department of Transportation (IDOT) has always and continues to report the Skyway as part of the Interstate Highway System, and the Federal Highway Administration also considers the Chicago Skyway an official part of I-90.[16]"

That's helpful! Thank you!

Storrow Drive in Boston is a parkway without a route number. Its because Storrow Drive is managed by the Massachusetts Department of Conservation and recreation.

Parts of it are MA-3 and MA-28.  Before 1989, parts were also US-1

I don't think anyone mentioned the Northwest Parkway in the Denver Metro.

In Toronto we have the Gardiner Expressway, Don Valley Parkway, and Allen Road, which are all controlled-access freeways and have no number associated.

It's also not a freeway.* I don't think this thread was intended to list 'almost-freeways' like some of the DCR parkways.

*You could make the case that the entirety of what is technically Storrow Drive (the roughly 2 mile portion from the BU Bridge to the Hatch Shell) is a freeway, as the only at-grade intersections on that stretch are 'official use only' driveways, but it'd be a real stretch. The same could be said for Soldiers Field Rd west as far as the Anderson Bridge.

Parts of it are MA-3 and MA-28.  Before 1989, parts were also US-1

Technically none of Storrow Drive is concurrent with MA 3 or MA 28. Heading north/eastbound, MA 28 joins the road at the Copley Sq interchange (by the Hatch Shell), and MA 3 joins at the Charles Circle interchange, both of which are on David G Mugar Way, Storrow Drive having ended at the Copley Sq interchange.

The Highway Capacity Manual (HCM) (7) defines a freeway as a divided highway with full control of access and two or more lanes for the exclusive use of traffic in each direction. Freeways provide uninterrupted flow (Note: "Uninterrupted"  is used to describe the type of facility, not the quality of the traffic flow at any given time. A freeway experiencing extreme congestion, for example, is still an uninterrupted-flow facility because the causes of congestion are internal.) Opposing directions of flow are continuously separated by a raised barrier, an at-grade median, or a continuous raised median (Figure 1-4). Operating conditions on a freeway primarily result from interactions among vehicles and drivers in the traffic stream and among vehicles, drivers, and the geometric characteristics of the freeway.

The AASHTO "Green Book" (13) defines freeways as "arterial highways with full control of access. They are intended to provide for high levels of safety and efficiency in the movement of large volumes of traffic at high speeds. With full control of access, preference is given to through traffic by providing access connections with selected public roads only and by prohibiting crossings at grade and private driveway connections".

No matter how substandard it is, it's still a freeway. Limited access, access only at ramps, cross roads grade separated, etc.

You think anyone will?

[hobsini2]

Has anyone mentioned Kentucky's parkways yet? Other than the section running I-69, aren't these unnumbered?

Also isn't the Chicago Skyway *technically* not part of I 90?

1. The Natcher Pkwy (Green River Pkwy) is now I-165 and is signed as of March 2019ish.  Interestingly though, the newer section that was built south of I-65 to US 231 is signed as KY 9007.
2. The Audobon Pkwy is unsigned KY 9005.
3. The Pennyrile Pkwy is unsigned KY 9004 as of July 2019 but is supposed to be I-169 eventually.
4. The Western Kentucky Pkwy east of the Pennyrile Pkwy is unsigned KY 9001.
5. There is still a section of the Purchase Pkwy (north of I-24/I-69 interchange) that is unsigned KY 9003.
6. The Louie B Nunn (Cumberland Pkwy) is unsigned KY 9008 but does have signs erected for Future I-66.
7. The Hal Rogers Pkwy (Daniel Boone Pkwy) is unsigned KY 9006 for most of it. Part is KY 80. But I would not consider this a "freeway". Way too many cross roads despite the numerous bridges over the parkway.
8. The Blue Grass Parkway is unsigned KY 9002.
9. The Bert Combs Mountain Pkwy is unsigned KY 9000.

Also, the Chicago Skyway is now officially part of I-90 again.

Hmm...I had thought it was considered by both names at that point.  Google Maps seems to think so.

Seriously...I'm from Massachusetts and I always thought Storrow ran from I-93 to the Pike exit.

Google Maps labels a lot of things incorrectly. It's unfortunately not really a good source.

Most people refer to the whole thing as Storrow, including east to I-93 and west to at least the Pike interchange, if not the Eliot Bridge, so don't feel bad for not knowing that it's not 'officially' named both.

Ontario has the following:

• EC Row Expwy, Windsor (only the municipal portion, provincial section has an internal 7000-series number)
• Highbury Ave, London (was provincial Hwy 126, no number upon transfer to CofL)
• Nikola Tesla Blvd, Lincoln Alexander Pkwy, and Red Hill Valley Pkwy, Hamilton
• Pearson Airport access road - 1.3 km of freeway, formerly Highway 409, Mississauga
• Gardiner Expwy, Don Valley Pkwy, Allen Rd - previously mentioned in thread, all in Toronto
• Queen Elizabeth Way - Provincial freeway, Fort Erie to Toronto (one small segment is co-designated with Hwy 403, but it in and of itself has no number designated or assigned to it)*

* - yes, while there is a popular misconception in the roadgeek community that it has an internal number but no, it does not have any assigned to it.

[Hwy 61 Revisited]

FDR Drive has no number.

I mentioned them early on.

Slight correction: That portion of the Mountain Parkway east of Exit 43 is unsigned KY 9009. The segments between Exits 43-46 and from just west of new Exit 70 to the route's end in Salyersville are four-lane freeway now.

I'm not sure if I mentioned this one up thread but part of Pacific Highway (Old US 101) in San Diego is a Freeway grade.  Interestingly part of Grand Loop Road near Old Faithful in Yellowstone National Park is a Freeway grade.  I want to say that was the only segment of fully limited access roadway ever built by the NPS. 

[sprjus4]

I want to say that was the only segment of fully limited access roadway ever built by the NPS.

Two roads constructed by the NPS in the 1950s and 1960s in the Washington-Baltimore metro are built to full freeway standards.

The northern 14 miles of the George Washington Memorial Parkway in Northern Virginia.

The southern 18 miles of the MD-295 Baltimore-Washington Parkway in Southern Maryland.

Today (well, pre-COVID-19), they serve daily commuter traffic, functioning as urban freeways. They do, however, restrict truck traffic. Maryland eventually wants to take the NPS portion of the MD-295 Baltimore-Washington Parkway over and widen it from 4 to 8 lanes north of I-495, upgrading it to interstate standards in the process. It's an important and congested route connecting Washington and Baltimore, along with the NSA Headquarters, BWI Airport, and suburbs in between, that supplements the 8 lane I-95 that parallels it to the north. I don't believe Virginia has any plans for the George Washington Memorial Parkway besides reconstructing the northern interchange with I-495 apart of the I-495 HO/T Lanes Northern Extension project.

Interestingly part of Grand Loop Road near Old Faithful in Yellowstone National Park is a Freeway grade.  I want to say that was the only segment of fully limited access roadway ever built by the NPS. 

Some, including me, may consider that short section of freeway in Yellowstone as having a number. And several of them: US 89, 191 and 287. And depending on who one asks, US 20 (not me).

[US 89]

How can it be 89/191/287 but not 20? No US highways are official within Yellowstone park boundaries.

in the GIS shape-files for the roads in Yellowstone, there is a labeled routing for each of the US highways that cross the park. US 89/191/287 is routed up the west side of the Loop, while US 20 is routed across on Norris-Canyon Road.

[sbeaver44]

Is Yellowstone the only National Park where roads aren't signed?  Are 191 & 287 signed in Grand Teton?

I'm trying to remember is US 441 is mentioned at Newfound Gap in Great Smoky Mtns NP.

I don't remember any reassurance markers, but US34 and US36 are acknowledged at their junction in Rocky Mountain NP.

None of the US Routes are signed in Yellowstone or Grand Teton.  They used to be signed in Teton but that got yanked as the Park expanded.
