Development of Evaluation, Rehabilitation, and Strengthening Concepts for Low Volume Bridges, Phase I Progress Report, HR-323, 1990

The primary objective of this project is to develop a design manual that would aid the county or municipal engineer in making structurally sound bridge strengthening or replacement decisions. The contents of this progress report are related only to Phase I of the study and deal primarily with defining the extent of the bridge problem in Iowa. In addition, the types of bridges to which the manual should be directed have been defined.
