This helped the Port of Long Beach surpass the Port of Los Angeles as the leading port in the United States for a time in the 1980s and 1990s, since the deeper seafloor meant that Long Beach could accommodate ships with deeper drafts than could Los Angeles. Dredging operations related to the construction of a gigantic new marine terminal at the Port of Los Angeles have since made both sides of the bay accessible to even the largest existing
