Cracking of the concrete decks on newly constructed bridges in Minnesota has become a significant concern. MnDOT has been collecting bridge deck construction and early age cracking information since 2005. Crack surveys were performed on 20 bridges. A statistical analysis of bridge data, including the updated crack surveys, was performed to determine if there were any relationships between variables collected on the forms and crack frequency, type, or time of development.
