Nicholson Completes Emergency Work on Indiana’s I-65
PITTSBURGH, PA – Nicholson Construction recently completed emergency repair work to an unstable pier supporting a bridge on INDOT’s Interstate 65. These repairs enabled a 37-mile section of the highway’s northbound lanes to be reopened after a four-week closure.
The highway was in the process of being rehabilitated and widened when the pier was damaged by steel piles driven into the water tight ground below it. The pier began to settle and eventually rotated ten inches.
Nicholson developed a design-build solution that used micropiles to transfer the loads to more stable soils and low-mobility grouting to fill voids and densify the upper subsurface layer.
