Gedeon GRC Consulting is proud to contribute engineering expertise to the Manhattan Tunnel Project, a pivotal segment of the larger Hudson Tunnel Project. This high-impact infrastructure effort is designed to enhance regional connectivity by linking HYCC-3 to the Hudson River tunnel through twin tunnels beneath 12th Avenue. A key feature of the project includes a massive access shaft engineered to retrieve tunnel boring machines, underscoring the scale and complexity of the work.
