At one point, Business Interstates were very common in major cities, however, most of them over the years have been decommissioned, leaving them mostly in smaller cities.
I would like to know, does anyone know examples of major cities that still have a Business Interstate? One example I know is Winston-Salem, North Carolina (a city with a population over 200,000), which I-40 Business was once mainline I-40.
Isn't Colfax Ave in Denver still technically considered I-70 Business?
Does Sacramento count?

It is definitely a contender, for sure.
Unless BL-70 in Denver was decommissioned it's Denver (650K)
Unsigned 375 BR in Detroit?

Colfax is still BL-70, but it always stays on surface streets. BL-70 is never on a freeway. (That is how I interpreted the OP's thread on the first read).
If we are going with Business Loops or Spurs which follow an actual limited-access highway or freeway, off the top of my head there is:
- BL-40 in Winston-Salem, NC
- BL-376 in Pittsburgh
- BL-80 in Sacramento
Going back to ANY road with a Business Loop designation, isn't there one or two short stretches of BL-8 in the San Diego Area?

I was referring to Business Interstates in general, not specifically those that are freeways. I guess Denver is the winner except if BL-8 still exists in San Diego.

I don't how technical this discussion is, but BL-376 isn't in Pittsburgh; it's in Moon Township.

Yeah BL-376 definitely doesn't count and it's not even getting all that technical...it simply doesn't actually serve any part of Pittsburgh.

Yeah... it is getting pretty far out into the burbs; though one could say that the Pittsburgh Metro area has a business interstate.

Well, if going by MSAs, then the Phoenix metro area has I-8 Business in Gila Bend, but very few people would actually consider Gila Bend as part of the Phoenix metro area.

Business-85 in southwestern Greensboro, NC (the section between I-73/I-85 and I-40). It used to be I-85 until the loop was built.
It is also duplexed with I-40 until I-40 duplexes with I-85 on the eastern side of Greensboro. But this very short section of road between the I-73/I-85 and I-40 isn't duplexed with another interstate.
There is another section of Business-85 south of Greensboro (just south of the loop). It is not in Greensboro city limits, but does pass through High Point (and Thomasville and Lexington). The entire road is not a freeway (some at grade intersections and traffic lights), but the part within High Point, IIRC, is freeway.
It's either I-375 in Detroit(unsigned) or I-70 in Denver
El Cajon Blvd in both San Diego/La Mesa and El Cajon are both BL 8, but neither portion is up to freeway standards.

Business Interstates don't have to be up to freeway standards. That's part of the reason why they have green and white markers instead of the red/white/blue ones.
Then the answer is Denver, followed by Sacramento.

The only BL I know of that's up to freeway standards is BL-80 in Sacramento.

For signed ones. BS-375 in Detroit is unsigned. I think that may take the tamale for biggest city with an interstate business spur (BS) or loop (BL).
In about 3 or 4 years, Denver's city population will likely be larger than Detroit's. There's about a 30,000 difference right now....
As business loop 8 remains signed on portions of El Cajon Blvd (although somewhat poorly), San Diego would be the winner of this contest, at least until the remaining signs are removed. San Diego is the 8th largest city in the U.S. Historically, Los Angeles (2nd largest city in US as of 2010 census) would have won had it kept it's BL 5 along San Fernando Road (old US 6-99), which I think was unsigned by the late 1980s but remained showing on the Rand McNally map of greater Los Angeles for years through the 1990s. Phoenix (sixth largest) would have also been a contender had it kept it's BL 10 in downtown, but that route went away I think in the early 1990s once I-10 was completed through central Phoenix. The next largest city with active business route after San Diego is Denver (#22) with Colfax Ave/BL-70.
How about BL 229 in Sioux Falls, SD? It is South Dakota's largest city at 164, 676 and it is a business interstate.
They actually just signed I-90 Business in Spokane, WA and Spokane Valley, WA on the old route for US 10. One of only two signed Interstate Business Routes I know of in the State.
Washington has BL-5 in Castle Rock and BL-90 in Spokane. I don't think there's anything else.
Does Oregon have a BL? I-84 just uses US-30. I-5 has OR-99 and OR-99E/OR-99W.
