Designing a connection between an historic elevated NYCT subway line and an underground line while assuring that it was aesthetically in keeping with the new Citigroup building was like putting together pieces of a jigsaw puzzle – complicated in the beginning but worth the effort in the end. The new glass enclosed transfer structure between the elevated #7 line and underground G line provides intermodal connectivity and brings the station into Americans with Disabilities Act compliance.
Our multidisciplinary design team worked collaboratively to make all the pieces of this complicated assignment fit just right. Our landscape architects developed a streetscape design to integrate the new entrance into the surrounding environment and closed off 45th Road to vehicular traffic to improve pedestrian circulation. Our civil and structural engineers and architects created the new glass enclosed station entrance and connecting structure, as well as managed the design work of the mechanical, electrical, and communications engineers. These efforts assured that the entrance and connecting structure, consisting of two new escalators, two new stairs, and three elevators, were functionally and aesthetically appropriate.
