I drove through there earlier today. The semi-circular IN 750 North Vernon bypass has been extended east of IN 3 (where the HB now has it) to reconnect to US 50 east of North Vernon, as shown in OSM/Mapnik.
AIUI, there are plans to move US 50 to the bypass, and convert the old route through North Vernon to Business US 50. The signage I saw indicates that changeover hasn't happened yet.
