10-23-13: Miami Tunnel: workers install components to a sub-generation plant in the deepest section of the port’s new tunnel. Fire retardant panels cover the wall. The future travel surface is full of mud. “We protect ourselves by washing the tunnel down 5 times a day to keep the work area free of stone dust,” explains Chis Hodgkins, communication chief for MAT Concessionaires, the private firm building the tunnel. Chris’s team will also run the tunnel’s operations and maintenance for the next 30 years.
