Pulice Wins Major SR 303L Interchange Project in Booming North Phoenix Corridor

$129 million project will improve mobility and support future growth near key semiconductor facility. 

The Arizona Department of Transportation (ADOT) awarded Pulice, a FlatironDragados company, a major freeway contract to improve mobility and capacity on the State Route 303L corridor in northwest Phoenix. 

The $129 million Bob Stump Memorial Parkway 303L project — located between 51st Avenue and Interstate 17 — aims to alleviate congestion and prepare the rapidly growing region for future traffic demands.  

“This project shows Pulice stands ready to support ADOT in addressing traffic and safety challenges in the rapidly growing northwest Valley,” said Victor Jimenez, president of Pulice Construction. “We’re proud to collaborate with ADOT and construction partners in shaping infrastructure surrounding critical developments like the TSMC facility and contributing to the future of transportation in Arizona.” 

The scope of work includes: 

• Widening SR 303L mainline between 51st Avenue and I-17. 

• Constructing four new directional interchange ramps. 

• Building five new bridges, including post-tensioned concrete and steel tub girder structures. 

• Installing 80,000 square feet of retaining walls and 33,000 square feet of sound walls. 

• Adding new drainage features, 125,000 square yards of concrete pavement and 12,400 tons of asphalt. 

• Implementing extensive environmental protection measures and cultural site avoidance protocols. 

  
  

The project sits at the doorstep of the 3.5 million-square-foot TSMC semiconductor facility, a significant economic driver in the area.

“As the interchange is currently built, it will not be able to handle future traffic demands,” said Chad Swint, Chief Estimator at Pulice. “The four new direct connect ramps will ease future congestion and make travel faster and safer.”  

Work on the project is expected to begin in early 2026 and finish in 2028.
