Port congestion has been a glaring part of the ongoing US supply chain crisis. The ports of Los Angeles and Long Beach together handle 40 percent of US imports. Last week, Southern California hit a record high of 100 ships floating off the coast, waiting to enter and unload their cargo, according to the non-profit Marine Exchange of Southern California.
