State and local officials have agreed to begin a program to conserve part of the historic Seven Mile Bridge in the Florida Keys.
Monroe County commissioners Wednesday approved a 30-year project to restore and maintain a 2.2-mile segment of the bridge between Marathon and Pigeon Key.
The span was built more than a century ago, when Henry Flagler constructed the Florida Keys Over-Sea Railroad.
In 1938 the bridge was converted for automobiles, and in 1982 the federal government built a new span. "Old 7" was retired and became a fishing pier and walking area, but the harsh marine environment has taken its toll.
Total conservation costs are about $77 million, with the Florida Department of Transportation paying 75 percent and the remaining funding coming from Keys governments.
