USA bridges structurally deficient; 900 in Texas

In a report that analyzed federal data, North Carolina dropped from the 9th worst state in the country for structurally deficient bridges to 11th.

According to a construction organization specializing in over-the-water platforms, it's the latter in the United States, with nearly 56,000 "structurally deficient" bridges scattered across the country, USA Today reports. At that pace, it would take more than two decades to replace or fix all of them, according to American Road & Transportation Builders Association (ARTBA) Chief Economist Dr. Alison Premo Black, who conducted the analysis.

More than one in four bridges (173,919) are at least 50 years old and have never had major reconstruction work, according to the ARTBA analysis. "It is outdated, overused, underfunded and in desperate need of modernization", said Alison Premo Black, chief economist of ARTBA. "But, we're also facing the challenge where a lot of the bridges built with the interstate system are coming due for major maintenance in the near future", he said.

INDIANAPOLIS, Ind -They're a familiar sight on every commute, but now a new study says thousands of American bridges are in disrepair.

Cars, trucks and school buses drove across structurally compromised bridges about 185 million times per day past year, according to the report. While these bridges may not be imminently unsafe, their inclusion in the U.S. DOT report indicates that they are in need of attention.

Although structurally deficient bridges may still be safe to drive on, they have defects or fix needs that can cause speed or weight limits to be imposed. By clicking on a state, a separate report on the state can be accessed, breaking down the breadth of the problem as well as the locations of each bridge. A bridge is classified as structurally deficient and in need of fix if its overall rating is four or below. However, at the current pace, it would take more than 20 years to fix every bridge.
