The $33-million project started in April 2010. The project included rehabilitation of the bridge structure and replacement of the bridge mechanical system of motors and pumps.
There were also improvements so the area is safer for pedestrians and bicyclists. Improvements come just in time for the NATO summit.
"We did want to have the bridge done as quickly as possible. We're going to have a lot of visitors coming in. We know that we can show the city of Chicago, the state of Illinois, in a positive light to the whole world," Gov. Quinn said.
An estimated 150,000 vehicles use that section of Congress Parkway each day.
