The 2013 Post-Tensioning Institute (PTI) Project Award winners exemplify the advantages of modern post-tensioning applications. The project of the year—Wacker Drive Viaduct Reconstruction, submitted by Alfred Benesch & Co. and T.Y. Lin International—is just one example of the many great projects PTI considered this year. Entered in the bridge category, the project is a remarkable example of urban reconstruction. Wacker Drive’s reopening in December 2012 was the first time both the lower and upper levels have been open fully to the Chicago public since 2010. Post-tensioning was one of the most critical elements in accomplishing the project’s main objective, affording exceptional flexibility in the design of every major infrastructure component. The team was able to accommodate heavy loads, unbalanced spans, and geometric anomalies by adjusting the horizontal layout and vertical drape of the strands, which is not feasible using other systems of construction.
