Frustrated by the U.S. 231 detour on Greencastle's south side? Just imagine your car going through this torn up section of Bloomington and Anderson streets. The closure of the highway began on Monday, with workers from Rieth-Riley Construction Co. Inc. excavating large portions of the street. The closure is scheduled for two months, as Anderson Street is completely reconstructed to make an official entrance to DePauw University. The official U.S. 231 detour follows U.S. 231 northbound to Veterans Memorial Highway westbound to South Jackson Street northbound and back to U.S. 231. Traffic traveling in the opposite direction will use the same detour in reverse.
