Northside Hospital Atlanta is tearing into a big emergency room expansion in Sandy Springs’ Pill Hill, betting that more space and a revamped entrance will help it keep up with a steady surge in patients. Construction on the two-story project quietly started in early April, and hospital leaders say the existing emergency department will stay open while crews work around it. The goal is to catch up with years of growth in ER traffic, which the hospital says hit roughly 68,000 visits last year as the metro area’s population and commuter traffic keep climbing.
In a detailed rollout of the project, Northside said it will renovate about 7,815 square feet on the ground floor and add a 67,537-square-foot, two-story wing that brings 18 treatment rooms, a new entry and waiting area, five triage rooms, and space for two additional emergency care teams. The two-story lobby will include stairs and an elevator and create an enclosed corridor that links the expanded emergency department to the hospital’s main lobby, according to Northside.
“We are proud to announce the expansion of the Emergency Department at our Northside Hospital Atlanta campus,” Chris Munn, the system’s director of emergency services, said in the hospital’s statement. Northside says the work will roll out in phases so the department can keep taking patients while construction is underway, with early site work tied to a partial reconfiguration of the Green Parking lot and a temporary shift of ED patient parking over to the Gold Deck.
Why Northside Is Building
Hospital officials point to a long arc of rising demand. Annual emergency visits have climbed from about 39,000 in the mid-1990s to roughly 68,000 in 2025, and the emergency department staff now numbers about 200 people, according to Axios. Axios also reports that the multi-phase effort is expected to cost about $47 million and is slated to wrap up in March 2028. Northside says the added capacity should make it easier to accept more ambulance traffic when nearby hospitals have to redirect patients because they are full.
Construction Timing, Parking And Patient Flow
Initial site work kicked off April 6, with contractors staging the build so emergency operations are not interrupted, according to WABE. The plan includes a 17,000-square-foot parking structure with 54 spaces for emergency patients and visitors, along with temporary closures or reconfigured lots as crews cycle through different phases. Hospital leaders say patient parking is being reserved in the Gold Deck while staff parking is shuffled to free up close-in spots during construction.
Local Medical Corridor And Capacity
Northside’s Atlanta campus sits in the stretch locals know as Pill Hill, a dense medical hub along the Perimeter that pulls patients from across the region. Its immediate neighbors include Children's Healthcare of Atlanta at Scottish Rite and Emory Saint Joseph’s, which together help shape how ambulances and specialty referrals move around the north Perimeter medical corridor.
Officials say the upgraded emergency department, with its 18 additional treatment rooms plus expanded triage, imaging, and team space, is intended to move patients through more quickly and cut down on the stretches when ambulances are diverted because of capacity issues. The expansion is pitched as giving Northside more flexibility to absorb patients during regional surges, especially when neighboring hospitals feel the squeeze.
