In 2000-2001, 500,000 cubic yards of material were dredged from the Potomac River for construction of a new Woodrow Wilson Bridge. New foundations were required for the new spans.

The dredge spoils excavated from the bottom of the Potomac River were barged to Charles City County for disposal. The material was placed in a former sand and gravel pit, on what was once part of the Shirley Plantation. Relatively dry material was removed from the barges by excavators and transported via trucks for spreading. Wet spoils were pumped through a pipeline to the disposal site. What was a "waste" at the Woodrow Wilson Bridge became a useful component of soil at Weanack, and corn crops were planted in it.1
