Since the P3 method encourages innovation and optimization of efficiencies, the current freeway design incorporates some changes from the early design concepts that minimize the right of way impacts while increasing safety and reducing traffic restrictions during construction. Innovation and efficiency examples throughout the freeway corridor include:
Half diverging diamond interchanges at Desert Foothills Parkway and 17th Avenue
Modifying interchanges to improve traffic operations and minimize right of way requirements
Double roundabout configuration at Estrella Drive
Shared-use path along the Pecos Segment
Pedestrian bridge in the Salt River Segment
