I-17

FLAGSTAFF – The Arizona Department of Transportation is starting a project to replace pavement on 29 miles of Interstate 17 south of Flagstaff in order to create a smooth driving surface and repair damage from winter weather.

The work will stretch from the I-40 interchange south to the Coconino County line at milepost 312. Crews will mill down the worn, rough pavement and replace it with new pavement. 

Let's go back 52 years to a familiar scene.

To prevent lower-height bridge decks along Interstate 17 from getting hit by trucks, ADOT employees explored ways to bring attention to the bridge decks. And found a solution that's working.

PHOENIX – With construction set to begin later this year on Interstate 17 between Anthem Way and Sunset Point, the Arizona Department of Transportation is hosting its second public meeting to share information and answer questions. 

ADOT encourages everyone to participate to find out what to expect while work is underway through 2025, and how the improvements will help reduce congestion and enhance safety and traffic flow along this busy 23-mile stretch of highway north of Phoenix.

With construction set to begin later this year on Interstate 17 between Anthem Way and Sunset Point, the Arizona Department of Transportation is hosting two public meetings to share information and answer questions. 

ADOT encourages everyone to participate to find out what to expect while work is underway through 2025, and how the improvements will help reduce congestion and enhance safety and traffic flow along this busy 23-mile stretch of highway north of Phoenix. 

Anyone can attend one or both meetings to learn more, provide input and ask questions. 

What takes 11 hours to empty, weighs just over 2,000 tons and can cover a football field half a foot deep? It's the 1,000 cubic yards of concrete that was poured over the weekend in conjunction with the Arizona Department of Transportation's Interstate 10 Broadway Curve Improvement Project.

The Arizona Department of Transportation has signed an agreement with the developer team that will design, build, operate and maintain the Interstate 17 Improvement Project from Anthem Way to Sunset Point. 

The total project cost is $445,940,000, which includes the construction cost by the developer team, along with ADOT’s cost to administer the project. 

CAMP VERDE – An Arizona Department of Transportation project to improve the Verde River bridges on I-17 near Camp Verde is underway to add capping to the bridge footings in the river bed to prevent erosion, protecting vital infrastructure on the primary route between Phoenix and Flagstaff. 

The work utilizes a method to channel river flow through the work zone by constructing a temporary “earthen bypass channel” to contain the river flow so crews can safely work outside of the area placing concrete caps over the footings of the Verde River bridges.

FLAGSTAFF – The Arizona Department of Transportation is starting a project to bring broadband internet access to more Arizonans by laying fiber-optic conduit along a 46-mile stretch of I-17 from Flagstaff to Sedona.

The project begins today as crews start laying fiber-optic conduit along southbound I-17 from milepost 340 in Flagstaff to milepost 296, just south of the junction with SR 179. During the project, drivers can expect right-lane restrictions along southbound I-17 where crews are working. Crews plan to install the fiber-optic conduit in 3-mile stretches at a time. 

A new bridge deck was poured for the project that replaces the I-17 bridge over Central Avenue. 

Drivers in northern Arizona should prepare for traffic shifts and lane restrictions on Interstate 40 at Exit 191 in west Flagstaff as crews continue project work to replace a bridge, according to the Arizona Department of Transportation. 

This location is approximately three miles west of the I-40 interchange with Interstate 17. 

We're throwing back to a busy rest area along Interstate 17 that comes with a great view. 

Half time's over! Crews kick off second half of the I-17 Central Avenue bridge project.

Murder hornets and a public health situation didn't keep us from completing some major projects in 2020.

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.

They say there is strength in numbers - and that is especially true when it comes to the girders used for bridges like the one on Interstate 17 over Central Avenue.

We are nearly half a year into our project to reconstruct the I-17 bridge over Central Avenue. While the project won't be finished until fall 2021, here's some photographic evidence of progress being made.

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