The drilled shaft foundations for the kcICON bridge over the Missouri River have been completed according to Dan Brown and Associates, LLC, the geotechnical engineers on the job. The 1700-ft long bridge conveys the I-29/35 over the River with the central spans being cable-stayed and supported by a single pylon in the river. The foundations for the central pylon consist of 8 10.5-ft diameter shafts socketed into bedrock. The land-based bents are supported on 6.5 to 8-ft diameter shafts and the abutments are on driven piles. Some of the drilled shafts were post-grouted as well. The project is scheduled for completion in the summer of 2011. Find much more about the project at the DBA website. (Photo by Dan Brown and Associates)
