The rebuild of Chicago’s historic Wacker Drive—this time, the double-decker road’s nearly 60-year-old north-south section—is in full swing. On May 10, Chicago-based contractor James McHugh Construction Co. reached a major milestone on the $300-million project when it poured 1,500 cu yd of concrete over a 10-hour period to complete a section of mainline deck. Composed of 13 in. of reinforced post-tensioned, high-performance concrete with a 2-in. latex overlay, the deck sits on a rebuilt concrete structure that is designed to last 100 years. Local concrete ready-mix supplier Ozinga Bros Inc. set aside 24 trucks for the continuous pour, which required about 170 loads.
