I-17

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!

See the demolition that will lead to a better bridge on I-17 over Central Avenue.

The important ongoing project to reconstruct the Interstate 17 bridge over Central Avenue south of downtown Phoenix remains in an early stage. But before the work got started, our staff at ADOT knew the bridge work zone would present challenges for drivers who use the stretch of I-17 between the I-10 “Stack” and “Split” interchanges.

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.

PHOENIX – A section of Interstate 17 south of downtown Phoenix will be restricted starting this weekend through fall 2021 for a freeway bridge replacement project.

The Arizona Department of Transportation is set to begin a $13.5 million project to improve the I-17 bridge over Central Avenue.

The existing bridge, which first opened to traffic in 1962, will be replaced by a modern structure with increased clearance for commercial trucks traveling beneath it as well as Valley Metro's future Central Avenue light rail line.

Interstate 17 is a great highway, but if it only runs between Phoenix and Flagstaff, why is it called an interstate?

PHOENIX – The Arizona Department of Transportation is accelerating a project to widen and improve the Interstate 17 bridge over McConnell Drive entering Flagstaff by closing McConnell Drive until early May, followed by other restrictions through mid-August.

McConnell Drive is scheduled to be closed around the clock from Monday, April 13, through Friday, May 1. Beginning Saturday, May 2, McConnell Drive is scheduled to be closed between 5 a.m. and 7 p.m. daily through Sunday, May 31, while crews work on the next phase of the project.
