Seven Mile Bridge The Seven Mile Bridge is a famous bridge in the Florida Keys, in Monroe County, Florida, United States. It connects Knight's Key (part of the city of Marathon, Florida) in the Middle Keys to Little Duck Key in the Lower Keys. Among the longest bridges in existence when it was built, it is part of the Overseas Highway in the Keys, which is part of the 2,369-mile U.S. Route 1.
Marion Memorial Bridge The Marion Memorial Bridge was a 4-span metal truss bridge which formerly carried U.S. Route 41 in Marion County, Tennessee. It was built in 1929. The main span was 369 feet, and the bridge had a total length of 1870 feet. The bridge was historic, and the Marion Memorial Bridge was listed on the National Register of Historic Places on October 25, 2007. The bridge featured an unusual truss configuration that is a hybrid of the Parker and K-Truss configurations. This bridge crossed the Tennessee River and Nickajack Lake. The bridge was replaced by a new concrete and box girder span which opened in November 2014, slightly delayed from its original completion date of August 2013 by conditions encountered in the construction of the replacement bridge footings. Since the construction of the new bridge's footings would involve blasting within 30 feet of the Marion Memorial Bridge, state officials closed the bridge to vehicle and pedestrian traffic on January 9, 2012, with traffic being re-routed to the Interstate 24 bridge south of the span. All of the metal trusses of the bridge were demolished and removed by June 2015. The bridge was delisted from the National Register in June 2016.
