(Reuters) – The Ohio River was closed to shipping traffic at locks and dam 52 in Paducah, Kentucky, on Wednesday due to low water after a vessel ran aground in the area, the U.S. Army Corps of Engineers said on Thursday.
* At least the fourth river closure at that location since September.
* Shipping expected to remain halted through at least this weekend, an Army Corps spokeswoman said.
* A queue of 32 barge tows waiting to pass through the area as of midday on Thursday, Army Corps data showed.
