EXPEDITED CONCRETE BOX GIRDER BRIDGE REMOVALS OVER THE INTERSTATE IN ONE-NIGHT INTERSTATE CLOSURES

As part of the I-235 reconstruction project in Des Moines, Iowa, the East 9th St. and Cottage Grove Bridges over I-235 needed to be removed. The concrete box girder structures could not be removed effectively during the normally allotted 20-minute Interstate closures. A special provision was developed to allow I-235 to be closed for one night for the complete demolition and removal of the bridges. One lane in each direction was to be open the next morning with the entire Interstate open early the following morning. This paper describes the demolition and removal procedures of both bridges, the traffic control measures taken during these processes, and relates which milestones were met and which were not met.
