History edit

When Route 79 was created in about 1930, it replaced the north–south section of Route 56, which had been created in 1922 between Troy and O'Fallon. The part of Route 56 west of Winfield became an extension of Route 47.

Route 79 had major closures as a result of the Mississippi River floods of 2019 and other recent floods. Its buckling pavement in summer 2019 was attributed to hotter and more erratic climate conditions.[1]
