MARTA safety inspectors certified that the tunnels which run below the Dome site were safe for trains to operate. GWCCA officials stated that the implosion would be broadcast live by WSB-TV as well as livestreamed on the official websites of the Falcons, Atlanta United FC, and Mercedes-Benz Stadium. Live coverage of the implosion on the Weather Channel was blocked at the last moment by a MARTA bus that stopped in front of the camera just seconds before the implosion. While the implosion was considered successful with the roof and a majority of the structure felled, the eastern wall and the northwest gate of the Dome were left standing after the implosion. Although the Dome's proximity to adjacent structures was a major concern, with Mercedes-Benz Stadium only away from the Dome, demolition officials stated that bringing the roof down was the biggest challenge due to its unique design. The Georgia World Congress Center and Mercedes-Benz Stadium were undamaged during the first implosion, although the new stadium did receive a heavy dusting. Initially, demolition officials stated that the two remaining sections would be brought down manually with hydraulic excavators; however, after inspections determined that the explosive charges did not detonate, a supplementary implosion took place on the morning of December 20 at 1:00 am EST. A window at one of the GWCC buildings was shattered during the second implosion but was quickly replaced. Following the implosion, most of the concrete from the Georgia Dome remained on site, crushed into smaller pieces to be used as infill material while steel and other materials were separated and recycled. Most of the Georgia Dome site became greenspace for tailgating at Mercedes-Benz Stadium and other community events. On April 21, 2017, GWCCA officials announced that The Home Depot acquired the naming rights to the park prior to its construction, adopting the name of "The Home Depot Backyard". Cleanup of debris from the Georgia Dome site was completed by late February 2018 with construction of the Home Depot Backyard beginning shortly thereafter; the new park officially opened on September 11, 2018. Ground was broken for a new high-rise convention center hotel on May 19, 2021; the new hotel will be located between the Home Depot Backyard and GWCC Building C, and will be the first newly-constructed hotel for Hilton's Signia brand. The new hotel is projected to open in January 2024. A historical marker erected by the
