 These problems were alleviated, but not solved, by the construction of a six-lane elevated bridge, which still stands, in the early 1990s.The issues would be remedied by the construction of the tunnel, allowing traffic to move between PortMiami and the MacArthur Causeway (which connects to Interstate 95 via I-395) without traveling through downtown.Federal funding for a preliminary study into the tunnel proposal was included in the controversial 1987 highway bill which was vetoed by President Ronald Reagan, who complained that the bill was a "pork-barrel" project.
