Abstract:  Pedestrian bridges are a great option for improving safety at road and rail crossings. When the University of Memphis began planning the expansion of their southern campus, which was separated from the existing campus by a heavily-trafficked freight rail corridor, a new pedestrian bridge therefore became a central component of that plan. The final design included a single, inclined tower, an asymmetrical fan cable arrangement, and a hybrid precast/cast-in-place composite deck. In this presentation, we will discuss the need for the bridge and how the unique geometry of this signature structure inspired innovative solutions to structural design and constructability challenges.  


Steven Lowinger has worked as a structural engineer in the Bridge Structure group at WSP since 2016. He holds a BA in Physics from Yeshiva University and a BS and MS in Civil Engineering from Columbia University. Steven developed the finite element model of the bridge and aided in the design of concrete pylons and drilled shafts. Previously, Steven has worked on LGA Airtrain, the inspection of Phase 2 of Second Avenue Subway and MTA Subway Repair projects. He is a member of ASCE and AISC.

Dennis Smith is a structural engineer at WSP in New York City, where he has worked since graduating from Princeton University in 2016. He is currently pursuing an MS in Structural Engineering at Columbia University. For this project, Dennis primarily worked on rebar and cable detailing, and construction support services. His other projects include the Throgs Neck Bridge deck replacement, the RFK Bridge anchorage rehabilitation, and the Lake Street Transit Center/I-35W Bridge in Minneapolis.
