    State of Our Bridges

    This choropleth map shows the state of bridges in the OVRDC region. Bridge ratings are averaged by township. Clicking on each township brings up all the bridges in that township, and highlights the deficient bridges according to their General Appraisal Rating.
    The map utilizes TurfJS for browser-based analysis.

    Note: A total of fifteen bridges in the region did not have a GA rating. For twelve of these, the sufficiency rating was used. Three others were eliminated from the analysis.
