This map shows which states have the most structurally deficient bridges

Large-scale, efficient infrastructure is a must-have for any economy to function competitively, and that infrastructure needs to be maintained and updated if a country wants things to run smoothly.

However, in the last few years since the financial crisis, infrastructure quality has deteriorated in many developed markets, including the US, according to a previously released report by the World Economic Forum.

Using data from the Federal Highway Administration (FHA) shared by the American Road & Transportation Builders Association, we put together a map showing which states have the greatest and least proportions of structurally deficient bridges.

"Structurally deficient" means that "one or more of the key bridge elements, such as the deck, superstructure or substructure, is considered to be in 'poor' or worse condition," according to the FHA, as cited by the ARTBA.

The four states with the highest proportions of structurally deficient bridges are Rhode Island (23%), Pennsylvania (21%), Iowa (21%), and South Dakota (20%). To put that in perspective, roughly one out of every five bridges in those states is structurally deficient.

On the flip side, the three states with the lowest proportions of structurally deficient bridges are Florida (2%), Texas (2%), and Nevada (2%). 

In any case, check out your state below.
