The project includes a five-story, 230,000-square-foot patient pavilion that will house 76 private patient rooms, 10 operating rooms, a radiology suite and a maternity care unit.
Existing care units and support areas also will be renovated.
Construction on the pavilion is expected to begin this summer.
Riddle Hospital joined Philadelphia-based Main Line Health in 2017.
