The completed $300 million reconstruction of Wacker between Randolph Street and Congress serves about 60,000 vehicles, half on Upper Wacker and half on Lower Wacker. The average daily traffic count on Congress is 75,700 vehicles. The improvements also feature wider sidewalks and crosswalks, used by 150,000 pedestrians on an average weekday, CDOT said. "Re-creating a double-deck highway boulevard through the downtown was no small task,'' Chicago Transportation Commissioner Gabe Klein said. "Now it's a modern, much more safe and efficient roadway whether you are in a car, using transit, biking or walking.''
