The main constraint for East Coast ports is that they are on the wrong side of the continent from most of the import/export demand in Asia. The Panama Canal isn’t exactly cheap, and some boats don’t even fit in the Canal!
They did recently build out a new expansion of the canal but these problems still remain. What is really cool is the fact that the New York port raised a bridge deck to support the new maximums. https://en.m.wikipedia.org/wiki/Bayonne_Bridge
