“Jones Act carriers have invested billions in vessels, terminals, and port infrastructure serving Puerto Rico,” said Trailer Bridge, in a February blog post. “These are not opportunistic deployments based on short-term rate swings. They represent long-term commitments to the trade, including modern vessels, LNG-powered ships, specialized equipment, and dedicated terminal operations.”
