That's just the most superficial issue about the bridge. Although they are similar there are huge differences between them. There are many similar bridges, they are cable stayed bridges, which is just a typology used in many bridges around the world, but each one must be different to another.
First is the size, Tappan is much bigger than this one, The main span is longer (making the towers taller) it is also wider, with four lanes in each direction vs 3 on Goethals. Finally, the total lenght of the Tappan Bridge is much longer, with a roadway extending 4 kilometers in the widest part of the Hudson.
There are many other differences, such as the soil where they stand. The towers of Tappan are just in the middle of the Hudson River, while in this case will be near the shore in a much smaller waterway.
There are many other details that must be different, such as the conection to the existing freeways.
So there is no way that they just could translate the Tappan Bridge here. They are two completely different bridges. And anyway, the two bridges are being built by two different agencies. Goethals by the Port Authority and Tappan by the State of New York.
