| Abstract: |
The recently completed Terwillegar Park Footbridge is a new stressed ribbon bridge located in Edmonton’s river valley. The bridge is 262 m in length and is one of the longest stress-ribbon bridges in the world. This bridge type comprises a thin deck, supported on highly stressed bearing strands, and post-tensioned to achieve the necessary stiffness and desired geometric shape. Associated Engineering, working as an erection engineer for Graham Infrastructure developed methodology to construct this bridge, described in this paper. One innovative accelerated construction method used was the creation of the ‘messenger’ loop system that facilitated bearing strand and precast panel installation. Furthermore, the construction erection team was required to provide geometric set-out during construction and involved modelling, monitoring and reporting of the bridge during construction. |
