At the time of its completion in 1982, Seven Mile Bridge (35,867’ long) in the Florida Keys was the longest continuous concrete segmental bridge in the world. The bridge utilizes a precast, post-tensioned box girder superstructure and hollow precast segmental piers, which increased the speed of erection. The structure was completed six months ahead of schedule and has earned eight awards, including an Exceptional Award for Cost Savings Innovation from the Federal Highway Administration. The bridge’s 264 spans carry the Overseas Highway. FIGG’s segmental alternate saved $7 million when bid against an alternate design.

The bridge was featured on the History Channel’s Modern Marvels series in a television show called Overseas Highway (http://www.tv.com/shows/modern-marvels/overseas-highway-333183/).
