Safety, efficiency, and durability help make pavement projects successful. The American Concrete Pavement Association (ACPA) has recognized several such projects with its 2006 Excellence in Concrete Pavement awards. The program honors owners, contractors, and engineers for pavement projects demonstrating quality, cost-consciousness, and minimal road-user delays.

The Oklahoma DOT took home a Gold award in the State Roads category, which it shared with contractor Duit Construction Co. and Cobb Engineering, for the CMAY-021N (005) Richardson Loop Interchange in Pontotoc County. Crews used a global positioning system to fine-grade and trim the curves, superelevations, transistions, and straightaways, which enabled them to achieve a better concrete yield. The $8.3 million project included removing the existing roadway, installing 131,000 square yards of 10-inch dowel-jointed concrete paving, erecting a four-span bridge, excavating 640,000 cu. yds. of material, and performing associated underground and sub-base work.
