Hello, and thank you for your report. The INDOT project at SR 46 and Smith posed a difficult challenge for temporary traffic control as the detour options were limited during construction. The marked detours were chosen and approved because they were the closest route that were accessible to all modes of transportation. The work will be concluding in the coming weeks but if there is a specific area of concern please feel free to contact the engineering department via the contact information included at https://bloomington.in.gov/engineering

No location info, but it seems this is a potential MOT question for engineering. Not sure if you will be able to follow up on this on without further information!
