Both types of Interstate-style markers can be seen on this junction assembly for Interstate 57 and Business Loop 57 at US 60, US 62, and Missouri 77 just east of Charleston, Missouri.
At this point, the concurent routes branch off: US 62 and Missouri 77 go through Charleston along with Business Loop 57, while westbound US 60 follows "southbound" (at this point, really westbound) Interstate 57, bypassing the city.
