What is the longest bridge in the United States?

The tallest bridge would be the I-278 crossing of the Verrazano Narrows in New York City -- the Verrazano Narows bridge. The double-decked span opened in 1964 and connects the borouhs of Staten Island and Brooklyn. It has a span of 4,260 feet and rises 224 feet above the water. That is a very large bridge however the highest interstate bridge in the United States is the Glade Creek bridge. This 2,179-foot (664 m) long deck truss bridge[3] towers 660 feet (200 m) above the creek bed, making it the highest Interstate bridge in the United States. And that's in West Virginia..!!
