Froggie's Notes:

- MS 15 is billed as being the longest state highway route in Mississippi, well over 300 miles in length.
- The route is also known for having a considerable gap in it, even though the gap did not exist in the early days of MS 15.  I'm not sure when this segment was decommissioned, but from MS 26 north to US 98 used to be part of a continuous MS 15, and even had a duplex with MS 29.
- All of MS 15 was added to the former 1987 Highway Program as part of Phase 4, with the goal of having a fully 4-laned MS 15 corridor throughout the state.  This carried over into the Vision 21 program, with the route having a legislatively-mandated "High Priority" status.
- Although the highway is part of Vision 21, there has been previous work done on the route over the last 3 decades.  This includes full or partial bypasses of Newton, Union, Philadelphia, Louisville (with MS 25), and Houston, as well as straightening out of several segments that were previously very curvy.

Froggie Suggests:

- Drop the Vision 21 segment from I-10/110 north to US 98 and instead focus on improvements along existing highways and roads as needed.  Traffic volumes simply don't justify building a 4-lane corridor through here.
- After performing basic road improvements, recommission the missing segment between MS 26 and US 98, using a routing along Melton Hatten Rd, French Gas Rd, MS 29, and Beaumont-Brooklyn Rd, then city streets within Beaumont.
- Widen to 4 lanes from I-59 south for about 3 miles.
- Incorporate access management from I-59 to the north side of Laurel.
- Widen to 4 lanes from the north side of Laurel to the north side of Bay Springs.
- Widen to 4 lanes from I-20 to MS 25, with the priority segment being from I-20 to Decatur.
- Consider upgrading part of the Philadelphia bypass, from MS 21 up to MS 19 North, to a freeway with interchanges at MS 16 West, MS 16 East, and MS 19 North.
- Widen to 4 lanes from Pontotoc CR 124 south of Pontotoc, north to the MS/TN State Line.
