What is smallest town with an Interstate-standard bypass?

[hobsini2]

What about Route 390? That's not a bypass realistically. Now when I-490 is built, that is a true bypass. I-355 is a bypass.

[I-57/Route 66 Fan]

Illinois 390

IL 390 doesn't strike me as being a beltway of anything nor does it go anywhere near Sugar Grove/Prestbury (the end of it is 20 miles away), though it does bypass Bloomingdale and Roselle.

Look at it's eastern terminus.

[dlsterner]

Because I'm convinced I'm the only one who actually looked at a map of Sugar Grove.

That's...not a beltway.

If it's not a beltway, than what is it?

I would think that to be a beltway, you should be able to drive around it ad infinitum(*).  There is no movement from eastbound I-88 to southbound IL 56, nor from northbound IL 56 to westbound I-88.

This is not a hill to die on.

OK partial beltway then, the town of Milan, IL has a slightly longer beltway, but it is not Interstate standard, and it goes around more of the town, that has 4,000 less people than Sugar Grove.

This is stupid.

To be fair, Illinois is so flat there's little experience to know which hills to die on..

Do you know what FIB stands for?

Oh yes, I lived in Chicago for a time.  Crash_It and dzlsabe fit the stereotype more closely.

Please note that I was born in Wisconsin despite living in Illinois for 46 years.

Not all - see Finland for example.

[Beltway]

In an effort to rescue this thread, Virginia has a lot of small towns with full freeway bypasses (i.e., no at-grade intersections, only interchanges).
Keysville (pop. 807) has US 15 Bypass
Appomattox (pop. 1919) has US 460 and VA 24
Courtland (pop. 1295) has US 58
Lawrenceville (pop. 1014) has US 58
Clarksville (pop. 1300) has US 15/US 58/VA 49
Gretna (pop. 1310) has US 29
Chatham (pop. 1219) has US 29
Coeburn (pop. 1598) has US 58 ALT

True, but the non-bypass segments of those highways are arterial highways with at grade intersections.

What he seems to be looking for is something like I-470 at Wheeling WV.

As a teenager, I did that a few times with the Capital Beltway I-495. We lived a mile from it in Alexandria.

Have never done that on the Baltimore Beltway or the Hampton Roads Beltway.

[kphoger]

To me, it just looks like two highways merging together on one side of town with the town in between.

Yep.  Nothing to see here, everyone, just a wye.

I haven't seen a new Virginia official highway map for awhile, so I wonder if they still have the freeway portions of their four-lane arterial routes marked in blue (signifying grade-separated interchanges) with the rest of the routes marked in red (signifying at-grade intersections).

AAMaps, and therefore presumably OSM in general, does this pretty well.

They still do, though specifically it's "limited-access roadways" marked in blue. There are some of them that have at-grade intersections, such as the VA 3 Bypass in Fredericksburg.

Don't look at New York though. LaSalle Expressway, Lake Ontario State Parkway...

Yikes.  They got NY 204 right, so how did they get those wrong?  Also noticed odd endpoints for the freeway on the Taconic (one looks like it might be at a median U turn!).

[Dirt Roads]

There are only a few towns in West Virginia that actually have a freeway bypass, none of which are up to Interstate standards:

US-60	1959	Belle	pop. 1,097 (2024)
US-21 (now US-19 Corridor L)	1961	Oak Hill	pop. 7,732 (2024)
US-250/WV-2	1975	Benwood	pop. 1,204 (2024)

For that matter, I guess West Virginia cities are small enough to be included in the list as well:

Clarksburg Expressway (now US-50 Corridor D)	1958, completed 1977	Clarksburg	pop. 15,262 (2024)
US-22	1977, completed 1993	Weirton	pop. 18,317 (2024)

Some (non-ursine) eejit decided to base classifications on functional classification and reverts anyone who changes them back.

O.o

Getting functional classes changed takes a LONG time. 

Functional class maps are good for determining federal-aid eligibility and not much else.

Whenever I'm searching through state DOT maps and find one of those, I think to myself, —Oh, yeah, sweet... oh, wait, never mind, that isn't actually what I was looking for.

Every single time.

Not to mention that these roads show as FC 12 (Urban Principal Arterial Expressway) in RIS (well, the eastern LOSP freeway section, and all of the LaSalle that isn't a stub ramp), so they should be marked as freeway on OSM if that's the criteria!

US-250/WV-2	1975	Benwood	pop. 1,204 (2024)

Are these really, though? Oak Hill has at-grade intersections at either end of its city limits, but the rest of US 19 is limited access. The shoulders don't look bad either.

US 250 and WV 2 beside Benwood are also controlled-access, but the shoulders would need widening in a few spots.
