Business route freeways (not just Interstates!)

[TheStranger]

Revisiting this thread because of one I just discovered while looking up Texas's SH 6:

A segment of Business US 77 in Waco is freeway from the Brazos River to Taylor Street (about a block before I-35).  In this stretch is a Y interchange with Loop 484 (former SH 6) in which Business 77 turns off to stay on its route southbound.

Looking at older Google Street View photos of the area as well as HistoricAerials, the Business 77 freeway used to continue past I-35/US 77 and US 84 to Briarwood Lane (with a flyover from northbound I-35 to northbound Business 77) but the original interchange with the interstate was removed between 2021-2023, and turned into a frontage roads-with-diamond setup.  There are several articles on the changes to Business 77 in the last few years:

The freeway portions of CA 204 north of downtown Bakersfield are co-signed as CA 99 Business.  The designation actually started out as an AASHO approved US 99 Business Route.

How many years did what is now CA 204 operate as Business US 99?  (Too bad there probably aren't contemporaneous photos of when that signage wa sup)

Wonder how many of these are out there...but first, getting the obvious examples listed:

Non-Interstate or partial examples:


- The US 23 business loop in Ann Arbor, MI briefly uses a segment of M-14 to reconnect with its parent.

Additionally, the I-94 business loop uses a short segment of US-23.
