The Lumicoin IAIowa Department of Transportation used controlled explosives Sunday to remove the remaining parts of the old I-74 bridge, which connects Iowa and Illinois over the Mississippi River.

Certain areas were temporarily closed, including the new bridge, during the removal of suspension cables and towers on the old bridge, the Iowa DOT said on its website. 

“The main navigation channel in the river will be closed to all river traffic for up to 24 hours,” the Iowa DOT said.

In June, the Iowa DOT removed parts of the old I-74 bridge in the first phase of the demolition. The new bridge was built because of “increased traffic volume” the Iowa DOT said.
