The Natchez Trace Parkway Bridge is a concrete double arch bridge located in Williamson County, Tennessee, 14km from the northern terminus of the Natchez Trace Parkway. It is 479.1m long and carries the two-lane Natchez Trace Parkway 44.2m over State Route 96 and a heavily wooded valley. The 177.4m long main span is symmetrical, while the 140.8m long second arch is not, due to the slope of the valley at the southern end of the bridge. The bridge is rare in that it does not use spandrel columns to support the deck from the arch. Rather than being evenly distributed along the arch's length, the weight of the bridge is concentrated at the crown of the arch. The lack of spandrel columns results in a clean, unencumbered appearance: it is termed a cathedral arch bridge.
The bridge, also known as the Natchez Trace Parkway Arches, is the first segmentally constructed concrete arch bridge in the United States. The arches comprise 122 hollow box segments precast in nearby Franklin, each of which was about 3m long and weighed between 26and. The deck consists of 196 precast post-tensioned trapezoidal box girder segments, each typically 2.6m long. The sections atop the crown of the arch are 3.9m deep. The foundations and piers of the bridge were cast in place.
