Commercial shipping came to a standstill on the Mississippi River  on Tuesday after a barge struck an auxiliary lock’s gate near Granite City, Ill. The barge jam, at one of the river’s busiest points, could last into the week, the Army Corps of Engineers said.

Corps crews were determining how the damaged auxiliary lock would be fixed, and a spokesman said it would likely be closed to traffic for a day or two. The auxiliary lock had been pressed into greater duty since last month when repairs began on the adjacent main lock.

No injuries were sustained in the accident, but the closure forced 11 southbound and five northbound tows, with a combined 87 barges, to park and wait.
