Project Overview

55 Marietta Street is a 21-story, 403,000 sq ft mission-critical carrier hotel and edge data center hub located in Downtown Atlanta, Georgia. Owned and operated by RadiusDC following its acquisition from Principal Real Estate, the landmark telecommunications facility plays an important role in the Southeast United States' digital infrastructure ecosystem. The building serves as a major network aggregation hub, supporting enterprises, telecommunications providers, cloud service platforms, and digital businesses that require reliable connectivity and access to carrier-dense infrastructure. Its extensive telecommunications environment features 22 on-net carriers and two Meet-Me-Rooms, providing customers with opportunities to establish connections with multiple network operators and interconnection partners. The facility's strategic position directly across the street from Digital Realty's 56 Marietta Street (ATL13) strengthens its presence within Atlanta's established connectivity corridor. This proximity creates opportunities for efficient interbuilding connectivity and access to a wider network of telecommunications and cloud infrastructure providers. 55 Marietta Street offers high-density colocation services and up to 9 MW of new critical IT capacity, supporting the growing requirements of enterprise computing, cloud workloads, and edge applications. Its direct subterranean cross-connect access to regional fiber backbones and cloud exchanges enables customers to establish low-latency connections across important digital networks. These capabilities are particularly valuable for organizations seeking scalable infrastructure, network diversity, and dependable access to cloud services. As demand for digital services continues to increase across financial services, technology, media, and enterprise sectors, facilities such as 55 Marietta Street provide essential infrastructure for connecting businesses to regional and national networks. By combining a large urban telecommunications footprint, carrier access, and expanded IT capacity, the building supports Atlanta's position as a key Southeast US destination for colocation and interconnection services. Its relationship with 56 Marietta further reinforces the strategic importance of the Marietta Street corridor within the city's data center and telecommunications landscape.
