State highway officials say a portion of State Road 246 in Vigo County will be closed for one week starting today for the repair of a railroad crossing. The highway will be closed from just east of US 41 at the tracks. State Road 246 is scheduled to reopen next Thursday, weather permitting. The detour follows US 41 south to State Road 48 east to State Road 159 north and back to S.R. 246.
