The Arizona Department of Transportation is touting another distinctive feature of the South Mountain Freeway.
“Already the largest single highway project in Arizona history,” ADOT said in a release last week, it “now has the longest bridge girders of their type in the state.”
The agency said it has installed 94 “extra-long” single-span girders on two bridges going in both directions over the Salt River.
Characterizing the girders as being “as long as a 17-story building and each weighing as much as 14 elephants,” ADOT said each girder weighs 169,000 pounds and extends 17 feet.
