A precariously perched two-lane roadway in Colorado National Monument needed to be widened. The Central Federal Lands office of the Federal Highway Administration designed a mechanically stabilized earth retaining wall to facilitate that widening. In order to work quickly, maintain a small footprint, and work within a limited excavation, the FHWA selected Launched SuperMicropiles™ as the solution for building the foundation to the wall. GeoStabilization International installed the Launched SuperMicropiles™ and met the FHWA goal of a fast solution that would minimize the size of the excavation and provide a permanent foundation support system. Moreover, Launched SuperMicropiles™ also proved to be an economical solution.
In June, GeoStabilization received a phone call about 7:30 am that KY 221 had slipped down the hillside creating a large drop in the pavement.
