The billion-dollar PortMiami Tunnel, which was supposed to open at the end of May, is now scheduled to open mid-to-late July.
The reason seems to be a safety precaution. Two of the tunnel's 44 installed fans, which control air ventilation, recently broke down after an unknown vibration, the Miami Herald reports. The Florida Department of Transportation says that until the cause of that vibration is known, Mat Concessionaire, which operates the tunnel, cannot open the tunnel.
The hours are ticking down for researchers trying to preserve some of the coral at the bottom of PortMiami’s shipping channel. This dash to harvest some of the reef that has made a home there reflects changing attitudes toward marine preservation.
The port will begin dredging on Saturday to accommodate bigger ships going to and from the expanding Panama Canal.
Even though not all of the coral can be preserved, the harvesting will create some unique research opportunities.
