River traffic up and down the Mississippi is expected to begin moving again Thursday morning after a barge accident last weekend.
Crews have been working to reopen Lock and Dam 27 near Granite City after a barge crashed into a barricade. When that happened, large rocks and debris spilled into the water around the lock and dam.
As of Thursday, nearly 63 boats and 455 barges were on hold up and down the river waiting to pass.
That's enough cargo to fill 24 thousand semi trucks.
According to the St. Louis Post-Dispatch, the Coast Guard was working to organize vessels and cargo to get through the lock in the best order based on various factors.
It could take up to 3 days to get traffic back to normal.
