The Raleigh Greenway system was the first community-wide open space development in North Carolina. One of the newest sections of the system is located at the North Carolina Museum of Art and is one of the only art-nature trails in the country. The trail opened in 2005 and is dotted with art inspired by the natural world, such as a giant brambly structure by Patrick Dougherty and a whirligig by Vollis Simpson. The two-mile trail ends in a pedestrian bridge over the Raleigh Beltline that connects it with miles of Raleigh greenway trails. The bridge is the longest pedestrian bridge in North Carolina.
