AATA Route 12 served a large loop involving the Blake Transit Center, Liberty Street, Stadium Boulevard, Maple Road, and Miller Avenue. It was redesigned and broken up into multiple routes in the AAATA Great Renaming of 2016.
The AATA actually ran two counter-circulating routes (i.e.: one clockwise, one counter-clockwise), labeled 12A and 12B.
- AATA Route 12A (counter-clockwise)
- AATA Route 12B (clockwise)
