The "75 Interstate" for Minnesota is news to me, though in both the 75
and the "60 two lane" cases, MnDOT does not necessarily need
Legislative approval. Per Chapter 169, Section 14, Subdivision 4 of
the Minnesota Statutes, the MnDOT commissioner can designate pretty
much any speed limit he/she wants for a given road section so long as
it's justified "upon the basis of an engineering and traffic
investigation". Although there was some discussion earlier this year
about bumping up speed limits on some Twin Cities freeways and rural
2-lane routes, to date MnDOT has yet to increase any speed limits above
the previous statuatory maximums.

For Mississippi, 4-lane divided highways have a 65 maximum, with two
exceptions. Those two exceptions are full freeway and are posted 70
MPH except within urban areas where they are 60 MPH...just like the
Interstates are. The two exceptions are US 78 (which is full freeway
in Mississippi), and US 82 east of Starkville.

Minnesota also uses a 65 MPH max on rural non-Interstate 4-lane
highways...though they theoretically could increase this per the
authority mentioned above.
