[2] Addison Circle and the surrounding area was built in 1997 to create a more traditional walkable urban town center;[3][4] it is a 133-foot-diameter (41 m) roundabout.
It weighs 410,000 pounds (190,000 kg) and required 650 US gallons (2,500 L) of custom "Sharpie blue" paint.
It was designed by artist Mel Chin in conjunction with landscape architect Michael Van Valkenburgh and with the aid of LeMessurier Consultants, and was fabricated and erected by Big D Metalworks of Dallas.
The panels follow a design using actual blueprints from Addison's municipal buildings, parks, bridges, and water pumping facilities.
Of the work Chin said “I chose to represent in this the physical representation of blueprints, the infrastructure that you don’t see—and to celebrate the ideas floating above you.”[1]
