About this weekend’s work: Eighteen girders will be placed in two spans while sections of east- and westbound I-10 are closed over the weekend of June 3-6; eight for the new southbound bridge and ten for the new northbound bridge over I-10 at 48th Street. The girders are constructed out of prestressed concrete: a combination of concrete, reinforcing bars and prestressed steel strands. 

The girders that will be set over the weekend weigh between 75 and 78 tons each and range from 149 to 157 feet in length. They will serve as the primary support for the deck portion of the new 48th Street bridges; the deck is the portion of the bridge that motorists drive over.

The I-10 Broadway Curve Improvement Project is identified in the Maricopa Association of Governments’ Regional Transportation Plan, funded by a half-cent sales tax approved by Maricopa County voters in 2004 through Proposition 400. MAG identified the need for this project to reduce travel times on I-10 during peak hours; improve airport access; support ridesharing and transit; and prepare the region for future growth projections.
