A portion of the field of 1,500 runners compete in the Seven Mile Bridge Run over the longest of 42 bridges on the Florida Keys Overseas Highway near Marathon, Florida, U.S., April 1, 2017. The race was begun in 1982 to mark the completion of a federally funded program to build a then-new Seven Mile Bridge and three dozen other bridges that replaced spans built in the early 1900s.
