CHICAGO (CBS) — The Columbus Drive bridge over the Chicago River will briefly close Thursday to make way for ducklings.

The bridge will close for an hour starting at noon for the Windy City Rubber Ducky Derby, an annual fundraiser for Special Olympics of Illinois, according to the Chicago Department of Transportation.

Those looking for cross should use the Michigan Avenue bridge to travel north or south over the river, CDOT said.
