Preferred developer selected for I-10 Broadway Curve Improvement Project

Construction to begin in 2021 on 11-mile segment

PHOENIX – The Arizona Department of Transportation has selected an apparent preferred proposer for the Interstate 10 Broadway Curve Improvement Project, the state’s first major urban freeway reconstruction project.

ADOT sought proposals from qualified developer teams vying to reconstruct the 11-mile section of the freeway, which is one of the busiest in Arizona. Three finalists were selected earlier to advance in the selection process. All three teams participating as finalists in the process were encouraged to use innovation and develop alternative concepts to save time and money.

Following an extensive review that included representatives from ADOT, the cities of Phoenix and Tempe and the Maricopa Association of Governments, Pulice-FNF-Flatiron Joint Venture has been chosen as the preferred developer. Key members of the development team include Pulice Construction, Inc., FNF Construction, Inc., Flatiron Constructors, Inc., and T.Y. Lin International.

ADOT plans to begin negotiations with the joint venture in November. If negotiations are successful, ADOT expects to finalize the contract by early 2021.Construction is scheduled to begin in mid- to late 2021 and take up to four years to complete. The final cost of the project will be determined during the negotiation process.

"Arizona continues to build the infrastructure of the future and strengthen our transportation network," said Governor Doug Ducey. "When completed, this project will help power Arizona's economic expansion and reduce travel times for hundreds of thousands of commuters."

Phoenix Mayor Kate Gallego, chair of the MAG Transportation Policy Committee, called the Broadway Curve “a critical connection for our region.”

“This project will improve safety and efficiency for hundreds of thousands of drivers who travel through the Broadway Curve each weekday and generate $658 million in new economic activity,” she said. “ It is delivering on a promise made to voters in Proposition 400 to improve our transportation system and reduce congestion.”

Work will take place on an 11-mile section of I-10 between the I-17 “Split” interchange and the Loop 202 Santan and South Mountain freeways in the cities of Phoenix, Chandler and Tempe and the town of Guadalupe. Planned improvements include:

  • Widening I-10 to six general purpose lanes and two HOV lanes between 24th Street and US 60.
  • Building a collector-distributor road system between Baseline Road and 40th Street to separate local and through traffic on I-10. 
  • Adding a fourth general purpose lane on I-10 from US 60 to Ray Road; and keeping the HOV lane.
  • Modifying I-10 connections at SR 143, Broadway Road and US 60 to improve traffic flow and safety.
  • Replacing ramps at I-10 interchanges at SR 143 and US 60 with new ramps, including new bridges.
  • Adding three pedestrian bridges to connect communities.

The I-10 Broadway Curve improvement project is funded in part by Maricopa Association of Government’s Proposition 400, a dedicated sales tax for transportation approved by Maricopa County voters in 2004.
