Interstate Business Route 57
Interstate 57 has a single business loop in southeastern Missouri. One could easily be considered along the 364 mile corridor through Illinois along old U.S. 54 or parallel IL 37 through southern reaches of the state.
The lone entry for Business Loop I-57 comprises a 2.92 mile route through the Mississippi County seat of Charleston. Cosigned with Missouri 105 along Main Street, the business route leads north from Exit 10 to U.S. 60 & 62 (Marshall Street) at the city center. U.S. 60 & 62 overlap with Business Loop I-57 east back to the freeway at Exit 12. The route is well marked.
