Crews work overnight Saturday to put up tub girders and diaphragms for the Zoo Interchange project in Milwaukee. According to WisDOT, the weekend closure was needed to install four new tub girders over the eastbound traffic lanes within the interchange. The work will one day support traffic on the system ramp from eastbound Interstate 94 to northbound I-41/U.S. 45.
