The Broken Bridges of Madison County

The 2015 National Bridge Inventory shows that more than 130,000 bridges in the USA are structurally deficient or functionally obsolete. The Washington Post has released an interactive map, How many structurally deficient bridges are in your county?, which shows the state of bridges in every country in the country. The map also allows you to view the inspection results for every classified bridge in your county.

The map at the top of article provides a choropleth view showing the number of structurally deficient bridges in each county. If you select a county on the map an interactive map of the county will load below the choropleth map. The county map shows all the classified bridges in the county and the number of bridges which have been classified as structurally deficient or functionally obsolete. You can also select any bridge's marker on the map to view its individual classification in the 2015 National Bridge Inventory.
