The Seven Mile Bridge, part of the 110-mile Ocean Highway, connects the Florida Keys to the mainland. This engineering marvel was once the longest continuous concrete bridge in the world. The original structure, the "Old Seven," was built with precast concrete and steel girders to adapt to local conditions but sustained significant damage from hurricanes, storms, and saltwater. This led to the construction of a modern bridge designed to withstand these challenges and accommodate increasing vehicular traffic, marking an important milestone in engineering history.
