• Abstract:
  Recent reports have indicated that 23.5 percent of the nation's highway bridges are ; structurally deficient and 17.7 percent are functionally obsolete. A significant number of these bridges ; are on the Iowa county road system. The objective of the investigation described in this report was ; to identify, review and evaluate replacement bridges currently being used by various counties in Iowa ; and surrounding states. Iowa county engineers, county engineers in neighboring states as well as ; private manufacturers of bridge components, and regional precadprestressed concrete manufacturers ; were contacted to determine the most common replacement bridge types being used. Depending ; upon the frndigs of the review, possible improvements and/or new replacement bridge systems were ; to be proposed.
