The Panama Canal expansion project aims to address capacity constraints by constructing a new set of locks and widening the existing canal. This will allow the canal to accommodate larger "New Panamax" ships carrying up to 13,500 TEUs of cargo. The expansion is expected to double the canal's traffic capacity and revenues by facilitating more efficient transport of goods between Asia, North and South America, and Europe. While this will offer shipping lines and import/exporters lower costs, its impacts on routing choices and North American ports will be influenced by toll pricing and competitive responses from alternate routes. Benefits will mainly accrue to US East Coast ports, with some potential cargo diversion from West Coast ports.
