Froggie's Notes:

- MS 12 takes a role of semi-importance across central Mississippi, as it falls between I-20 and US 82.  The section between I-55 and Kosciusko was considered important enough to be included in Phase IV of the 1987 Highway Program, and now a High Priority under MDOT's Vision 21.
- MS 12 has a significant-length duplex with US 82 which, unlike others across the state, is actually signed.
- A recent project rerouted MS 12 on the east side of Columbus.  Where MS 12 previously left US 82 at the Military Rd interchange, MS 12 now continues with US 82 to the MS 50 interchange, has a brief duplex with MS 50, then heads north via a rebuilt Harris Rd and a new bridge across Luxapalila Creek back to old MS 12 northeast of Columbus.  This was done to bypass a substandard and low-height railroad bridge on old MS 12 northeast of US 82.

Froggie Suggests:

- Widen to 4 lanes from Sturgis to Starkville.
