In a continued effort to meet the Santa Clarita Valley’s health care needs, work is under way to expand the emergency department at Henry Mayo Newhall Memorial Hospital. Director of Facilities Bob Knoblauch said the $9 million project is now in its second phase. “This is the major addition to the building,” he said of the construction, which will more than double the existing 7,700 square-foot emergency room to 16,600 square-feet. The expansion will increase the number of emergency room beds from 21 to 33.
