The Arizona Department of Transportation (ADOT) announced it used carbon fiber strips that are “coated and strengthened with a reinforcing polymer” to fix girders on two state highway bridges in Phoenix. According to ADOT, one of those bridges is no longer listed as structurally deficient as a result.

QuakeWrap strengthening was applied to two bridges: The overpass at I-17 and Jefferson Street -- not considered structurally deficient – and the 19th Avenue overpass, which earlier had been labeled the most-traveled structurally deficient bridge in the state by the American Road & Transportation Builders Association. The bridge’s status has since been upgraded.

“Our ADOT Bridge Group focuses on using new and innovative bridge-repair technologies that enhance safety while saving time and taxpayer dollars,” ADOT Senior Bridge Engineer William Downes told Composites Manufacturing magazine. "We’re likely to use it again if and when repairs are needed.”
