Once the tunnel opens to traffic it will take cargo trucks from Interstate 395 bypassing congested streets to reach the port.
“The completion of the excavation of the westbound tunnel marks another major milestone in the construction of the Port of Miami Tunnel Project which is a great example of public-private partnerships and we look forward to the last phase leading to its completion in May 2014,” said Juan Kuryla, deputy director at PortMiami.
Harriet will now be dismantled and recycled for future projects. Many electrical, hydraulic and mechanical parts will be sent back to the manufacturer, Herrenknecht. The rest of the material will be recycled and disposed of in the most environmentally friendly manner.
While the boring is complete, work on the project will continue until next year. Workers still must build the roads inside the tubes, each of which will have two traffic lanes. Several passageways will connect the tubes for use in case of emergency and for maintenance.
