Crews have finished placing support beams for the half-mile South Mountain Freeway bridges that will span the Salt River.
The last of the 292 girders were installed last week, the Arizona Department of Transportation said.
“Many of the girders are very long and heavy, weighing 169,000 pounds and extending 170 feet in length,” ADOT said in a release, noting they are nine feet longer than any signle-span girders the agency has used for a bridge.
The bridges, between Broadway Road and Southern Avenue, represent about a third of the 1,000 girders to be installed on 40 bridges throughout the 22-mile corridor that will link 59th Avenue and Chandler interchanges on I-10 when it is completed late next year.
