The new Tappan Zee Bridge, officially named the Governor Mario M. Cuomo Bridge after the former New York Governor, is a twin cable-stayed bridge built to replace the original Tappan Zee Bridge over New York's Hudson River. The new twin spans are located to the north of–and roughly parallel to–the existing Tappan Zee Bridge, crossing the Hudson River in an east–west direction.  Construction began on the project in 2013.

Brugh industrial Engineering designed, developed and implemented a state of the art leveling control system to manage bridge span motion.  The system was mounted on the Left Coast Lifter, a floating derrick barge used to assembly bridge components.
