Governor Andrew M. Cuomo announced the beginning of formal construction of the New NY Bridge to replace the Tappan Zee with installation of the first permanent piles that will comprise the foundation of the new bridge.
The bridge is scheduled to be completed in just under five years from the start of formal construction making it one of the nation’s largest construction projects to be completed in such a short time.
“This week, we are putting shovels in the ground and starting formal construction on a new bridge to replace the Tappan Zee, the largest infrastructure project New York State has undertaken in decades,” Governor Cuomo said. “After more than a decade of delay, New York State has moved this project forward at a dramatic pace while working with the community, involving the public and protecting the local environment. Once completed, drivers in Rockland, Westchester and surrounding areas will finally have a safer, less congested bridge that will include a walkway for pedestrians and bikers and accommodates future mass transit.”
