ADOT has completed this major pavement project to improve the worn, rough freeway pavement. Crews recently completed final lane striping on I-17, ending major restrictions needed for the project.

Project construction started in May 2024 and was completed on schedule.

The project involved removing the worn top layer of asphalt, repairing the existing concrete pavement where needed and diamond grinding to smooth the concrete pavement using specialized machines with rotating drums containing diamond-tipped blades. Crews also replaced older steel bridge deck joints between elevated sections of the freeway.

ADOT appreciates the patience of drivers and nearby residents and the cooperation of the city of Phoenix during this $10.2 million project, especially when work required closures in challenging locations with limited alternate routes. Weekend closures focused on providing safe conditions for workers and motorists and allowed crews to efficiently complete the diamond grinding and deck joint replacements.

ADOT expects to start an I-17 resurfacing project between SR 74 and Anthem Way by this summer. Full freeway closures are not anticipated for that asphalt resurfacing project. Most work is planned using lane restrictions during overnight hours.
