The Port of Miami Tunnel (also State Road 887) is a 4,200-foot (1,300 m)[3] bored, undersea tunnel in Miami, Florida. It consists of two parallel tunnels (one in each direction) that travel beneath Biscayne Bay, connecting the MacArthur Causeway on Watson Island with PortMiami on Dodge Island. It was built in a public–private partnership between three government entities—the Florida Department of Transportation, Miami-Dade County, and the City of Miami—and the private entity MAT Concessionaire LLC, which was in charge of designing, building, and financing the project and holds a 30-year concession to operate the tunnel.[4][5][6]
The project was approved after decades of planning and discussion in December 2007, but was temporarily cancelled a year later. Construction began in May 2010. The tunnel boring machine began work in November 2011 and completed the second tunnel in May 2013.[7] The tunnel was opened to traffic on August 3, 2014.[8] In the first month after opening, the tunnel averaged 7,000 vehicles per day, and nearly 16,000 vehicles now[when?] travel to the port on a typical weekday.[1]
