4. New York
New York, New York… It’s going to be one bumpy ride in the concrete jungle. Especially on the bridges. There are 17,462 constructions of this kind, and 1,928 need to be repaired as soon as possible. The most critical is the I-278 over Relief at I-278 over The Narrows. It comes as no wonder if you know 175,362 cross it on a daily basis. The bridges built in the 40s are also a potential hazard.
