Then Quinn and Emanuel reached their accord in the waning days of the spring legislative session. The billboard measure that got the ball rolling on the site approvals was passed by the Illinois Senate the same day a House committee advanced a broad bill containing pet projects sought by the mayor and the governor. It included the mayor's plan to expand McCormick Place and build a new hotel and basketball stadium for DePaul University and also a measure to construct an airport near Peotone, an idea Quinn has supported.
