PROVENCHER CABLE-STAYED PEDESTRIAN BRIDGE
An extensive public consultation process led to the Provencher Paired Bridges solution, consisting of vehicular and pedestrian bridge structures, to replace the existing Provencher Vehicular Bridge which had reached the end of its service life. The new Provencher Pedestrian Bridge is a 2-span, 200-m-long, 5-m-wide, cable-stayed bridge that spans the Red River in the central business district of downtown Winnipeg immediately north of The Forks, where the Red and Assinboine Rivers meet. The signature feature of the bridge is a transversely inclined pylon developed to provide a continuous walkway and to help balance the dead load forces. A 370-sq-m center plaza is also supported off the pylon and provides additional dead load used to balance out some of the forces in the pylon due to its incline. Two pylon balance stays were also used to further reduce the unbalanced moments in the pylon. Aesthetics, personal safety, and lighting have been given high priority for this unique structure. One key innovative focus is the structural health monitoring (SHM) which was incorporated into the design throughout the pedestrian bridge structure, in association with ISIS Canada. The design of the SHM system required the collaboration of a diverse group of engineers and provided a unique opportunity for engineering students at the University of Manitoba to participate in this state-of-the-art project. Performance of the cable-stayed bridge can be monitored and evaluated continuously using an interactive, remotely monitored Data Acquisition System that incorporates fiber-optic sensors, conventional electric strain gauges, thermocouples 1-D and 3-D accelerometers, wind monitor, and inclinometers to measure strains, natural frequencies, temperatures, and wind speed. Looking to the future, this continuous monitoring of the bridge will help to optimize maintenance costs and minimize capital costs, resulting in savings to owners and taxpayers.
