When we last checked in on Good Samaritan Hospital's Medical Plaza and Outpatient Pavilion, steel had barely progressed to the second level above ground.  Flash forward six months, and the frame of the 190,000 square foot structure is mostly complete.  Standing seven-stories tall, the $80 million expansion project topped out in a January ceremony.  The state-of-the-art facility will eventually house the hospital's radiology and oncology departments, in addition to an ambulatory surgery center.  Designed by Irvine-based Ware Malcomb, the expansion building will share a two-story lobby with one of the hospital's existing structures next-door.  The finished product will also include a ground floor cafe and a street facing window display focused on medical history.  Good Sam's newest wing rises at a time when the formerly derelict City West neighborhood is experiencing a flurry of renewed interest from developers.  Last February, Holland Residential opened a 210-unit apartment building one block east of new medical building.  Further west, Sonny Astani plans to break ground this year on a mixed-use development at the intersection of Wilshire Boulevard and Valencia Street.  The "New Jersey," of Downtown?  Not for much longer.
