Rib For the Eye: Context-Sensitive Design Does the Job in the Field of Engineering and Aesthetics

The context-sensitive design of the Troup Howell Bridge in Rochester, NY, features a 132-m-long tri-rib arch span. The project is in its final stages and is expected to be completed in the summer of 2007. Replacing a bridge built in 1954 to connect Troup St. on the west side of the river to Howell St. on the east, it was widened and altered to become part of the federal interstate system in 1974. It crosses the Genesee River and is in a prominent location. That affected design decisions, which favored a thinner deck, made possible by the location of extremely competent dolomite granite close to the surface. The rib construction and fabrication is described, along with the hanger arrangement. A fan-shaped orientation was chosen and is illustrated by a photo. As a gateway to the downtown, it is being built in stages to avoid gridlock.
