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.
