Florida green lights Port of Miami Tunnel

12 October 2011

Florida’s Department of Environmental Protection announced Friday that it has decided to approve the final permit for the USD 1bn Port of Miami tunnel project.

This permit will allow the 13-diameter TBM to begin boring as early as November. The Herrenknecht TBM arrived in Miami this summer.

The project will consist of two tunnel drives that connect Watson Island and Port of Miami, for a length of 3,900ft (1,189m).

The agency also signed off on depositing spoils on Virginia Key for a restoration project, as long as environmental officials are able to certify the soil is clean.
