Redi-Rock in Action: Highway & Bridge Case Studies

Limestone retaining walls create roadway ramp

The Parklands, Louisville, Kentucky

Creating access to a hilly park system presented some daunting challenges, and retaining walls were required to create access. "The high efficiency of the PC System really made it possible to design tiered walls with those loads at that height," said Engineer Clint Hines, PE. "It would be hard to make it work with anything else."
