Explanation of the indicator:
A strong transportation infrastructure is important to a community's economic health. Transportation and distribution of commercial and industrial goods and materials requires sound bridges and well-maintained roads. The Genesee County Road Commission is responsible for 369 bridges within the County. The bridges are inspected bi-annually by certified Road Commission employees. MDOT then formulates a Federal Sufficiency Rating (FSR) based on the inspection report. Bridges are classified as "structurally deficient" if the FSR indicates poor conditions.
In some cases, County-level data are not available from the same data source used by the State. In other cases, County-level data are not available for the same time frame used by the State. In these instances, data sources and time frames were selected that most closely match those of the State. Due to this difference, it must be noted that comparisons may not be completely equivalent in all cases. Michigan's data source is the U.S. Department of Transportation, Federal Highway Administration.
