UPDATE: Doug Nintzel with the Arizona Department of Transportation says repairs have been made to the girders of the I-17 overpass at 19th Avenue in Phoenix, and that the report about deficient bridges is outdated. Ninzel says the bridge will be taken off the list of structurally disabled bridges in Arizona.
The most dangerous overpass in Arizona has been named.
Americans are crossing nearly 56,000 structurally deficient bridges millions of times every day. These bridges have one or more key components in poor condition, a problem that will cost trillions to fix. Business Insider named the most structurally deficient bridge in each state, with the I-17 over 19th Avenue taking first in Arizona. This overpass is not only the most structurally deficient in the state but also the most traveled every day at 123,000 daily crossings. However, there are plenty more that follow. 3% (214) of Arizona’s bridges are structurally deficient and 8% (649) are functionally obsolete. Overall, nearly 2,400 bridges in the state need some sort of repair, a task that would cost Arizona $1 billion.
