Abstract:This summary report investigates the current body of knowledge about the relationship between bridge skew angle and bridge deterioration rate and applies those findings to New Jersey bridges. Tools used in the study were graphical analysis (histograms and a scatterplot with regression lines) and statistical methodologies, specifically analysis of variance (ANOVA). The source of the skew angles of all New Jersey bridges was the Federal Highway Administration Long-Term Bridge Performance InfoBridge™ Web portal. The study team calculated the number of years that passed before a bridge’s condition rating declined by one rate.
