After browsing through the Alabama milepost maps, it appears that ALDOT has designated at least four new state routes:
* SR 300 is short (less than 0.8 mile) connector between US-11/43 and I-20/59 at Exit 62 in Tuscaloosa County
* SR 301 is an even shorter (0.428 mile) connector between US-78 and I-20 in Calhoun County, designated along the former route of U.S. 431. ICYMI, U.S. 431 is now co-routed with I-20 between Exits 188 and 191.
* SR 378 is the designation of Finley Boulevard in the northwest and north sections of Birmingham, between US-78 (Arkadelphia Road) and US-31 (Carraway Boulevard/26th Street North), a distance of just over 2.3 miles.
* SR 382 is the designation of the former route of US-82 though Centreville.
I don't think any of these routes are signed. Why did they even bother with the designations?
QuoteI don't think any of these routes are signed. Why did they even bother with the designations?
Probably because the routes are still considered part of the state highway system.
SR-378 looks like a newly taken over route, and SR-300 may be too.
Yes, 378 is "newly taken over". But because it's part of the state highway system, ALDOT gave it a number. That was my point.

I found 300 on a ALDOT node map (http://www.dot.state.al.us/dsweb/_pdf/regwc/63-TuscaloosaCounty.pdf) (section 4C), but 378 is not shown (http://www.dot.state.al.us/dsweb/_pdf/regec/37-Birmingham-s14.pdf) on Finley Avenue. I can't find AL 301 on the maps (http://www.dot.state.al.us/dsweb/_pdf/regec/8-Calhoun-s12.pdf), but I think that was even more recent.
(Seems like a neat coincidence between former hidden SR 1 and the state numbering system hitting the 300s at just the right time.)
I keep looking for AL 378 signs when I drive to Birmingham, only to not find any.
I drove down to Tuscaloosa Friday. There are no signs for SR-300 at Exit 62 off I-20/59, on US-11/43 or on the route itself.
