Bridging Arizona’s Freeways: How concrete bridge girders are made 

Several concrete bridge girders have been placed throughout the I-10 Broadway Curve Improvement Project and by the project’s end, dozens of these girders will have been placed within the project area. 

Bridge girders are the beams that support the deck portion of a bridge which is the part of the bridge that motorists drive on. 

Many of the concrete girders for the I-10 Broadway Curve Improvement Project are made in the south Phoenix area, off 19th Avenue and Lower Buckeye Road.
