Notes:
Parallels I-20 during its route through Mississippi. Also has two duplexes with
I-20, including a fairly significant stretch through Warren and western Hinds Counties.
Much of the old roadway has become the frontage road between Edwards and Clinton.
A 4-lane section bypassing the main part of Meridian to the south was in-place as early as
1957. This included a folded diamond interchange (with VERY tight ramps) at US 11 South/MS
19 North and a cloverleaf at old US 45 South/22nd Ave (present day MS 145 South).
Most of this bypass was later upgraded into today's I-20/59 through Meridian.
