t's been deemed the worst bridge in the Quad Cities and now, officials have announced their plans on when it will be fixed. The Illinois Department of Transportation says the Centennial Bridge that spans from Rock Island, Ill. to Davenport , Iowa will be shut down for an entire month in the summer of 2014. A specific date hasn't been picked, but the hope is to start the work after Bix weekend (the week of July 27, 2014) with completion before the Labor Day holiday weekend (Friday, September 5, 2014). There may also be some lane closures and construction prior to the shutdown. The latest inspection from the summer of 2013 shows the structure of the Centennial is in serious condition and a high priority for repairs.
