On September 22, 1985, a group of 300 professional workers completed the temporary work of art The Pont Neuf Wrapped. They had deployed 450,000 square feet (41,800 square meters) of woven polyamide fabric, silky in appearance and golden sandstone in color, covering the bridge. The fabric was restrained by 8 miles (13 kilometers) of rope and secured by 12.1 tons of steel chains encircling the base of each tower, 3.3 feet (1 meter) underwater.
