Pittsburgh, PA – June 2, 2011 – Missouri’s Interstate 44 is considered one of the most frequently traveled highways in the central United States. In early March of 2011, Nicholson Construction was contacted to perform an emergency response grouting operation on the Gasconade Bridge, part of I-44 westbound, over the Gasconade River in Laclede County.

During construction of the drilled shaft foundations for Temporary Bent No. 6, it was determined that voids were present both beneath and adjacent to the north footing for Intermediate Bent No. 6. Test borings by MoDOT indicated that the void varied in depth from zero to five feet, but the horizontal extents were unknown upon Nicholson’s arrival to the site.
