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 3 m (9.8 ft) long and weighed between 26 and 41 metric tons (29 and 45 short tons) . The deck consists of 196 precast post-tensioned trapezoidal box girder segments, each typically 2.6 m (8.5 ft) long. The sections atop the crown of the arch are 3.9 m (13 ft) deep. The foundations and piers of the bridge were cast in place.
The bridge has won many awards for its design, including a Presidential Award for Design Excellence in 1995, and an Award of Merit from the Federal Highway Administration in 1996. The Eleventh International Bridge Conference named it the single most outstanding achievement in the bridge industry for 1994. The bridge "impressed the... jury with its aesthetically striking double-arch design, which shows exceptional sensitivity to the historical context of the site."

I love the composition on this shot. low to the ground and at a angle the scale of the bridge is made larger. Great shadows and use of light!
