The Anne Arundel Medical Center Auxiliary has pledged $3 million to support the expansion of the Annapolis, MD, hospital campus, officials announced. The pledge will help fund the $400 million "Vision 2010" project at AAMC, which includes two new buildings, four parking facilities and two bridges. Part of the project is an eight-story tower with 50 private rooms and eight operating rooms. This new facility will expand the emergency room by 40%, and provide a pediatric care unit at the medical center.
