I-17 Black Canyon Freeway

PHOENIX – Drivers who travel I-17 at night will need to plan ahead to avoid major delays as the highway is closed regularly during the weeknight overnight hours for controlled rock blasting over the next several months. The blasting is necessary work as part of the I-17 Improvement Project from Anthem Way to Sunset Point.

PHOENIX – Now that construction is officially underway for the I-17 Improvement Project from Anthem Way to Sunset Point, there is some important work taking place to protect the natural landscape that is part of this scenic corridor. 

Crews have started removing native vegetation, including saguaros, palo verde trees and ocotillos, along the 23-mile project corridor so it can be cared for and closely monitored during construction, then eventually replanted alongside an improved wider highway. 

Heading to the high country to play in the snow is a tradition for many Arizonans. But before you go, make sure you Know Snow, and have a plan for smooth travels.

PHOENIX – The southbound Interstate 17 on-ramp at Thunderbird Road and off-ramp at Cactus Road will be closed for several months starting Wednesday night, April 28, for an ongoing regional drainage system project.

The southbound I-17 frontage road between Thunderbird and Cactus roads also will be closed as crews continue the installation of pipes to move stormwater in the area.

Drivers should plan on using alternate routes as needed, including other nearby on- and off-ramps at Greenway Road or Peoria Avenue, while the following restrictions are in place:

This unassuming piece of weathered pavement is actually part of the grand, sweeping story of the Old Black Canyon Highway.

Though it's not quite as new or flashy at the diverging diamond at Happy Valley, we shouldn't overlook the new interchange on I-17 at Pinnacle Peak.

The diverging diamond interchange at Interstate 17 and Happy Valley is opening this month. What does that mean? Let us tell you!

We've recently said goodbye to the roundabouts at Happy Valley Road. Here is our final ode to this sometimes maligned traffic interchange which did its job.

The use of thermal detection cameras to spot wrong-way vehicles on freeway off-ramps along Phoenix-area freeways will continue to grow, especially after the cameras have worked well as part of a pilot project along Interstate 17. 

As one example, you can look ahead to significant stretches of Loop 101 currently being widened to also have the thermal camera wrong-way vehicle alert technology added.

The Arizona Department of Transportation has already expanded use of the technology, with plans to do more as time and funding allow.

Drivers may have noticed some changes to I-17 at Central Avenue, but more is coming this weekend as we rebuild the bridge there.

Work to build a new, larger Interstate 17 bridge over Central Avenue south of downtown Phoenix is now underway as ADOT and partner agencies look ahead to improvements beyond the freeway itself. But the progress also means drivers should consider using alternate routes, including Interstate 10, while the bridge reconstruction requires I-17 lane closures.
