Defying common construction limitations, the Indiana Department of Transportation (INDOT) started a large excavation and embankment project in the dead of winter. With 24-hour operations and by chemically treating the embankment soil, the construction team, led by Walsh Construction, Chicago, successfully placed over 1 million cu yd of fill, often in sub-freezing temperatures. This remarkable effort kept a key project on schedule, improving both the highway and air transportation system around the Indianapolis International Airport.
