January – February 2015 Infrastructure SHOWCASE
The Portland Cement Association recognized these nine bridge project winners during the American Concrete Institute Fall 2014 Convention in Washington, D.C. These winning projects were constructed between 2011 and 2013, and they cover a variety of structure types and construction methods.
Wolfcreek Bridge on State Route 9 – Del Rio, Tenn.
The original bridge, built in 1926, was slated to be replaced but instead was rehabilitated using precast elements for the spandrel columns, spandrel caps, fascia beams and slab panels. The arches received additional reinforcing steel and a self-consolidating concrete encasement on three sides. Strengthening the arches provided the capacity necessary to widen the roadway by 7 feet, 2 inches to provide two 12-foot lanes with 2-foot shoulders.
Based in Washington, D.C., with offices in Skokie, Ill., the Portland Cement Association represents cement companies in the United States. It conducts market development, engineering, research, education and public-affairs programs. More information on PCA programs is available at www.cement.org.
