Abstract:
The new eight-lane Zilwaukee Bridge in Michigan replaces an aging four-lane drawbridge that was a hazard to both navigation and freeway traffic. The new post-tensioned, segmental, precast concrete box-girder structure actually two bridges, each measuring 1.5 miles (2.4 km) long and 125 ft (38 m) high] was constructed using the balanced cantilever method.
