Rockefeller University's Cable-Stayed Bridge

New York, NY

The first cantilevered cable-stayed bridge in New York City was built to connect the North and South sections of Rockefeller University. It officially opened in November of last year but landscaping and safety enhancements have continued into 2000.

Students and staff can now avoid the heavily trafficked East 63rd Street as well as enjoy a new landmark symbolizing the scientific achievements of the University. "By providing a direct, safe pedestrian access, the Campus Community Bridge continues the mission of this institution in supporting dedicated scientists in the important work they do," states Arnold J. Levine, M.D., university president and strong supporter of the bridge.

Being cable-stayed, the Campus Community Bridge, is less invasive to the landscape because it does not need deep girders and intermediate supports like those found in traditional pier-and-beam structures. The 123-foot long main span is supported by ten galvanized steel cables, which are attached to the deck at 23-foot intervals. The cables pass upward, through the main tower, and down again into tieback towers that are anchored into the concrete footings. In order to further minimize its interference with the view of the East River and surrounding landscape, the bridge stands 34 feet above the street and its deck is only 30 inches deep.

The elegant design culminates at the 90-foot high, white, V-shaped main tower. This bifurcated tower safely supports the branching structure and holds five of the ten supporting cables.

The $1.9 million bridge was designed by engineer Matthys Levy, P.E., of the Manhattan-based Weidlinger Associates, Inc. and architect Wendy Evans Joseph, AIA. The entire project, including utilities, landscaping by Thomas Balsley Associates and building renovations, totalled $8 million.
