This major infrastructure project included a .75 mile (1.1 km) long twin-tube highway tunnel for two 12 foot traffic lanes with curbs, walkways, ventilation fans and additional safety features, that connected the MacArthur Causeway on Watson Island to the Port of Miami on Dodge Island. The tunnel created a new connection under the main shipping canal, known as Government Cut. This improved traffic flow to the city’s cruise and container port on Dodge Island while relieving traffic congestion on downtown Miami streets.
