A Tappan Zee Bridge construction milestone was completed earlier this month. However, it’s not something that the thousands of motorists that cross the existing bridge each day will ever see. It’s located almost the length of a football field below the Hudson River.
The pilings for the piers that will support the two main towers of the new bridge are now in place. When the project is completed in 2018, more than 1,000 piles will be sunk in the riverbed to support the 43 piers on which the roadway will be built.
