The Post-Tensioning Institute (PTI) has recognized a number of roads, bridges, and other construction projects with its 2006 PTI Awards. Structures constructed or rehabilitated in the past five years using post-tensioning as a component were eligible.

One of the 12 Awards of Merit the association passed out was given to the Montgomery County (Ohio) engineer's office for the Siebenthaler Avenue Bridge project, completed in 2004. The structure—which carries vehicle, bicycle, and pedestrian traffic over a river—has four post-tensioned arches, measures 263 feet long, and features a deck area that is 15,780 square feet. Total cost for the bridge was $5.7 million.

In addition, the PTI handed out five Awards of Excellence, including to the Ohio DOT's Perry Street Bridge replacement, a 724-foot structure with four traffic lanes. For a complete list of winners, visit www.post-tensioning.org.
