Americans cross over bridges about 185 million times a day, without giving much thought about whether or not it's safe. In a new report released by the American Road & Transportation Builders Association, out of the 612,000 bridges in the United States, nearly 56,000 have been deemed structurally deficient.
"America's highway network is woefully underperforming. It is outdated, overused, underfunded and in desperate need of modernization," says Chief Economist Dr. Alison Premo Black, who conducted the analysis.
The bridges are inspected and rated on a scale of zero to nine, nine meaning the bridge is in "excellent" condition. A bridge is classified as structurally deficient if its overall rating is a four or below, meaning "poor" or "worse" condition.
Although these bridges may not pose and imminent threat, they are in need of attention. According to Black, state and local transportation departments better get to work, estimating it would take more than 20 years to replace or repair the 55,710 bridges on the list.
With 41% of the nation's bridges over 40 years old that have never undergone any major reconstruction, their deteriorating conditions are causing road closures and limiting access for cargo trucks. Even busy bridges like the Brooklyn Bridge and the Arlington Memorial Bridge are corroding, which could cause more than an inconvenience if conditions plummet.
So which states are home to the worst bridges? Iowa, Pennsylvania, Oklahoma, Missouri, and Nebraska. While Washington D.C., Nevada, Delaware, Hawaii and Utah have the fewest deficient bridges.
Monitoring structural and efficiency concerns during construction and maintenance projects is crucial to ensuring safety on the job. That's why MadgeTech designed data loggers specifically for bridge strain or civil engineering solutions to measure and monitor the safety of new and pre-existing structures.

Norway has become a country of "firsts" in the world of transportation, implementing measures such as banning gas-powered cars and boycotting cars from entering the capital's city center. Now, the nation has its sights set on the sea with a multi-million dollar plan that would help ships avoid the treacherous stretch of Norway's coastline.
The wait is over, the MadgeTech Titan S8 Portable Data Acquisition Logger is now available to order! Equipped with eight input channels, this versatile data logger is the ultimate companion for industrial manufacturing engineers and much more.
Energy efficient products all flooding the marketplace as people become more conscientious about the environment and saving money. In the U.S. alone, building efficiency products and services grew 8% last year, reaching $26.4 billion. With the advanced energy industry worth $200 in the U.S. and $1.4 trillion worldwide, it's no surprise energy efficient technology is now being applied to concrete.
