Fisherman’s Channel terminates in a turning basin centered on the existing Lummus Island turning basin. The turning basin now has a depth of 50 feet and a diameter of 1,500 feet. The North Channel contains the cruise ship berths and has a current depth of 36 feet.

Construction is officially completed on the Miami Harbor Deepening and Widening Project. The project began in October of 2013 and completed in September of 2015 with the removal of over 5 million cubic yards. This project marks the first major port deepening to -50 ft Mean Lower Low Water in the southeastern United States.  Along with deepening, mitigation construction is also completed (over 12 acres of artificial reef and 17 acres of seagrass beds). The alternative financing Project Partnership Agreement (PPA) allowed for the non-Federal sponsor to advance the entire Federal share of the project, advancing the completion of construction years ahead of schedule. Secondary project related impacts via sedimentation to adjacent benthic habitat are still being analyzed. Concluding assessment of project related impacts are confounded by the documented catastrophic and regional-scale coral bleaching/disease outbreak that started in the fall of 2014. The Port and pilots have recently expressed future plans for additional cruise berths and accommodation of 14,000 TEU vessels. The current Miami Channel was designed and built to accommodate the Susan Maersk 6,000 TEU vessel.
