Esri Releases Interactive Map Showing U.S. Bridge Conditions

The iconic Brooklyn Bridge in New York City is considered “the most troubled” bridge in the country, according to a new trove of bridge condition data compiled by the GIS and mapping technology company Esri.

The company recently released the U.S. National Bridge Inventory, an interactive mapping tool that shows the conditions of hundreds of old bridges around the nation, which are 100 years old or older…

The bridge condition data comes from the Bureau of Transportation Statistics. Bridges are ranked as good, fair or poor. Some 68.3 percent of the 1,430 old bridges included in the map are ranked as fair, with 16.7 percent of them receiving a good rating, and 15 percent receiving a poor rating. The average age among the bridges is 116.2 years, with a daily traffic count of more than 28.3 million vehicles.
