A Bridge for Progress: Building Hudson Bridge foundation while maintaining ecosystem. In late 2013, Tappan Zee Constructors (TZC) began replacing the existing 3.1 mile bridge across the Hudson River in New York. The existing bridge (est. 1955) served more than 138,000 vehicles a day, but had corroded. Read how Industrial Flow Solutions™ customizable Stancor® P/S Series high head dewatering pumps remedied two big concerns for this project. First, the bridge’s concrete foundation had to cure properly, which required cooling water to run 150ft into the air at a flow rate that would maintain the integrity of the structure. Second, ensuring the Hudson River water temperature would remain at viable levels for the underwater ecosystem.
