SAVANNAH, Ga. (AP) — Before workers can start to deepen the busy shipping channel to the Port of Savannah, they first must remove a Confederate shipwreck still sitting at the bottom of the Savannah River after 150 years.

The CSS Georgia was an armored warship that never fired a shot in battle before Confederate troops scuttled the ironclad in December 1864 to prevent its capture by Union Gen. William T. Sherman. Now its wreckage stands in the way of dredging the river to make room for larger classes of cargo ships.

The Army Corps of Engineers scheduled an update Thursday on efforts to bring the ship's wreckage to the surface. Officials have estimated the recovery will cost about $14 million, a relatively small chunk of the harbor deepening's $706 million price tag.
