An expansion of the Detroit People Mover potentially would bring additional employees and patients to Henry Ford Health System and would enable the large number of students who move back and forth between the medical school at Wayne State and Henry Ford to do so more easily, according to William Schramm, a senior vice president with the health system. Representatives of Wayne State and The Detroit Medical Center were among those who attended a recent meeting of employers along the Woodward Corridor. They hope to raise funds to study a northward expansion of the system.
