University Avenue Pedestrian Bridge Replacement

As part of a school project, Jim and I was tasked with designing a replacement for the University Avenue Pedestrian Bridge at the University of Waterloo. Working in collaboration with Plant Operations, we developed a structural design that meets current engineering standards while enhancing pedestrian experience. The project involved creating a full Engineering Calculation Package and Drawing Package to support the proposed design and demonstrate its feasibility and alignment with the university’s infrastructure goals.

The existing bridge, built in 1970, has shown signs of deterioration, including cracks in the concrete and damage to the windows. Our design aimed to revitalize the South-East portion of campus, especially near the older Engineering buildings, by introducing a visually striking and structurally sound bridge. Inspired by Zaha Hadid’s architectural style, we incorporated tilted arches and suspended cables to create a bold, futuristic look. The glass walls along the walkway allow for natural light and scenic views, making the bridge not just a crossing but an experience. We wanted the design to reflect the university’s commitment to innovation and to serve as a source of inspiration for fellow Architectural Engineering students—especially those who can see it from the CPH 3604 Studio.

To meet the project criteria, We ensured the bridge included a 2.2-meter-wide pedestrian walkway, floors that support 9 kPa live loads, and roofs that support 3.7 kPa. The structure is supported by three concrete piers, maintaining their original locations, and features a funicular arch and cable system. We selected structural steel with a modulus of elasticity of 200 GPa and yield strength of 600 MPa, and concrete with a compressive strength of 50 MPa. All structural members are under 15 meters in length. Through this project, we’ve applied engineering principles to a real-world scenario, blending aesthetics with functionality, and showcasing what’s possible when bold design meets solid mathematical proof.
