text: Over 9.6 million tons of cargo and over  (FY 2018/2019) of intermodal container traffic move through the seaport per year. The economic impact from cargo operations at PortMiami to Florida amounts to $35 billion.
  As of 2021, nearly 1,000 cargo ships docked at the port. In terms of TEU, China is PortMiami's largest trade partner, while Honduras is ranked first in terms of trade value. Computers represent the port's most valuable export, while insulated wire and cable are considered the most valuable import.
  Design and infrastructure
  The port currently operates eight passenger terminals, six gantry crane wharves, seven Ro-Ro (Roll-on-Roll-off) docks, four refrigerated yards for containers, break bulk cargo warehouses and nine gantry container handling cranes. In addition, the port tenants operate the cruise and cargo terminals which includes their cargo handling and support equipment.
  To retain the port's competitive rank as a world-class port, in 1997 the port undertook a redevelopment program of over $250 million which is well underway to accommodate the changing demands of cruise vessel operators, passengers, shippers and carriers. To further resolve accessibility, the PortMiami Tunnel was constructed in 2010 and completed in 2014, providing direct vehicle access from the port to the interstate highway system via State Road 836, thereby bypassing congestion in downtown Miami.
