Notes:
Section east of Waynesboro didn't exist until after construction of a bridge over Alabama
River in early '30s.
Although it's not mapped, there is no longer a duplex with MS 27 in Monticello, due to a
new MS 27 bypass of Monticello.
Will eventually be all 4-laned, under 1987 Highway Program. Next most likely section
to open up will finish up 4-laning west of I-55.
Future interchange with US 45 near Waynesboro will be a cloverleaf.
