Abstract
A case study is presented of a bridge on Interstate 471 in Campbell County, Kentucky. The south approach to the bridge is a side-hill fill. During construction, the south intermediate piers tilted as a result of movement in the south approach foundation. Construction was temporarily halted on the south approach embankment, allowing pore pressures in the foundation to dissipate and slowing the movement. The piers were than reconstructed.
The south approach end bents were instrumented with earth pressure meters. The piles were instrumented with slope inclinometers. Most recent data show that movement is continuing and the present factor of safety is approximately 1.03.
