Abstract
<p>Montreal’s Champlain Bridge was the first large scale use of prestressed concrete in Canada. A lack of understanding of corrosive effects from the long term use of de-icing salts has, over the decades, led to severe corrosion of the concrete girders. A poor drainage system and water infiltration through the pre-stressing anchors contributed to accelerating deterioration. A decision to replace the bridge was taken in 2011 only 49 years after its opening.</p><p>Today, the most vulnerable girders are instrumented and the owner, The Jacques Cartier and Champlain Bridges Incorporated, has installed steel trusses beneath the exterior concrete girders as a risk management strategy.</p>
