The Port of Miami mega project is celebrating a significant milestone today. A massive 41-foot diameter tunnel boring machine will start excavating the first of the twin tunnels that will connect the Port of Miami with Watson Island. The TBM will reach the port in about 6 months and turn around to complete the other tunnel. The target project completion date is May 2014. [Source: NBC Miami via ASCE SmartBrief.
