The State of Our Bridges

The Bridge Sufficiency Rating is an indexed value that takes into account a variety of factors including physical inspection of the bridge, traffic, number of lanes, etc. The result is a percentage comparing the current conditions of the bridge to the same bridge if it was newly constructed. The BSR is utilized for funding as well as understanding bridge conditions. A low BSR rating does not mean that a bridge is unsafe. The tables and maps below include those bridges in the OVRDC RTPO region that are inspected by the County Engineers Association of Ohio.

Jackson and Lawrence County are clearly outliers in the region, and this may be due to data errors as well as a measurable difference in bridge sufficiency for those counties. A future post will compare bridges using the General Appraisal rating. It will be interesting to see how the analysis differs using this variable.
