Survey of Non-Arched Historic Concrete Bridges in Virginia Constructed Prior to 1950
This study rectifies this lack of information and analysis of non-arched concrete bridges built before 1950 (a cut-off date chosen because, in general, a structure must be 50 years of age or older to be considered historically significant under National Register criteria). Given the average monetary cost of $10,000 per consultants' study, and an average time frame of 90 to 120 days, it is estimated that this project has already saved the Virginia Department of Transportation more than $500,000 and eliminated a typical three to four month delay for each project. Projected savings arising from this project are estimated at approximately $2.5 million over the next ten years. As construction and maintenance projects are initiated on older non-arched concrete bridges, the benefits from this survey in costs and time saved will continue to accumulate. The project consisted of field survey, data tabulation, documentary research into historic non-arched concrete bridge types, and comparison of the resulting information on bridge chronology, technology, and usage during the first half of the 20th century.
