Are you serious? a SEVEN mile bridge..like really? wow, im concerned. --ACTUALLY the bridge is 6.79 miles (35,862 feet) long. Please check your answers before posting, assumption is overrated :) ~Coyote♥
It depends on how big the bridge is and what it is made out of. A bridge with three teeth in it made out of non-precious metal can cost around $400. A six or seven unit zirconia bridge can cost as much as $2500.
Construction of the original bridge began in 1908 as part of the Florida East Coast Rail Line. Four years after construction began, the bridge was complete. Construction of the new bridge began in 1979 and was finished three years later.
