Hundreds of barges and vessels are lined up on the Mississippi River waiting to pass through the Port of St. Louis. It's the result of the Army Corps of Engineers closing Lock 27 near Granite City because of a damaged protection cell. The lock opened early Thursday morning, but traffic is still backed up all the way to the Riverbend.
The Granite City-area lock is the busiest on the river, but traffic ground to a halt earlier this week after the discovery of the damage on the protection cell.
That's Army Corps of Engineers Rivers Project Operations Manager Andy Schrimpf. He says the Corps is getting the traffic flowing again based on a list that prioritizes the vessels, taking into account various factors. Traffic is expected to be back to normal by this weekend.
