Tanner Health System is planning a $50 million expansion at the Carrollton facility, with work to begin in September. The system plans to add the first floor of a three- to four-story tower to house a new emergency department, expand its parking deck and add space to expand its surgical capability. The expansion will include a new helipad to accommodate the increased number of air transports. The expansion has been on the wish list for some time. The Carrollton facility has seen more and more patients, both in the emergency room and the surgical unit. The hospital started seeing a large increase in visits as it developed its heart program.
