Connected to the Washington University Medical Campus by a pedestrian link, the ambulatory cancer center will feature 96 exam rooms; 88 infusion bays; radiology, breast imaging and chemistry laboratory departments; 430 parking spaces above the main lobby on floors two through four; and a three-bay loading dock in the lower level.
