Schedules are subject to change due to inclement weather or other factors. ADOT plans and constructs new freeways, additional lanes and other improvements in the Phoenix area as part of the Regional Transportation Plan for the Maricopa County region. Most projects are funded in part by Proposition 400, a dedicated sales tax approved by Maricopa County voters in 2004.

FLAGSTAFF – A series of highway improvement projects which included rockfall mitigation in the area of the State Route 89A switchbacks in Oak Creek Canyon north of Sedona has been completed, according to the Arizona Department of Transportation.

Traffic restrictions south of the SR 89A Oak Creek Vista scenic overlook have been lifted. 

Three ADOT projects allowed crews to remove loose material and stabilize a cliff face along the switchbacks where a rockslide occurred in March 2023, as well as remove a large rock overhang just north of the city of Sedona. The SR 89A Pumphouse Wash Bridge near the switchbacks was improved and ADOT’s team has now finished an erosion and sediment control project.

That recently completed project included the installation of a new pipeline to direct storm runoff away from the switchbacks area cliff face and into an improved culvert that carries the water toward Oak Creek. Construction contracts for the three projects totaled $11.1 million.

ADOT and its project team collaborated with local and regional safety agencies to maintain emergency vehicle access and be prepared for events, including wildfires, that might require a response.

PHOENIX – Work improving the Interstate 17 pavement surface in north Phoenix will occur only overnight this weekend, with southbound I-17 reduced to one lane beginning on Friday, Saturday and Sunday nights.

• Southbound I-17 will be narrowed to one lane overnight only between State Route 74/Carefree Highway and Dixileta Drive from 9 p.m. Friday to 9 a.m. Saturday; 9 p.m. Saturday to 9 a.m. Sunday; and 9 p.m. Sunday to 5 a.m. Monday. 

The Arizona Department of Transportation is continuing a much-needed project along I-17 between Happy Valley Road and State Route 74. An older and rough top layer of asphalt pavement has been removed and specialized equipment is now being used to diamond grind the base concrete pavement, creating a smoother, safer and longer lasting riding surface along 6 miles of I-17. 

Drivers using I-17 southbound during these restrictions should budget extra time. Despite what a travel app may recommend, they should avoid attempting to detour on neighborhood streets that aren’t designed for freeway traffic. 

Future weekend restrictions for this project are currently scheduled as follows:

• Beginning Friday night, Oct. 11: Southbound I-17 narrowed to one lane starting at SR 74/Carefree Highway and closed at Loop 303/Sonoran Desert Drive, with traffic using off- and on-ramps.
• Beginning Friday night, Oct. 18: Southbound I-17 closed at Loop 303/Sonoran Desert Drive, with traffic using off- and on-ramps, and then narrowed to one lane between Loop 303 and Happy Valley Road.

ADOT encourages drivers to sign up for project traffic alerts at azdot.gov/i-17HappyValleySR74.

Real-time highway conditions are available on ADOT’s Arizona Traveler Information site at az511.gov, the AZ511 app (download for Apple or Android devices) or by calling 511.

PHOENIX – Southbound Interstate 17 will be closed at Loop 303 from 10 p.m. Friday to 5 a.m. Monday, Sept. 13-16, for ongoing pavement improvement work, with traffic taking the off- and on-ramps and then using one lane until Jomax Road.

Drivers should allow extra time, consider traveling during non-peak morning or nighttime hours and stay on the designated detour route.

To help keep traffic moving through the work zone, Loop 303/Sonoran Desert Drive will be closed under I-17. Eastbound Loop 303 traffic can reach northbound I-17 by taking I-17 southbound to Happy Valley Road. 

ADOT offers these additional tips to assist drivers when I-17 weekend closures are scheduled:

• Stay on the detour route regardless of what a navigation app may suggest. This is the best way to reduce delays for yourself and others. Avoid attempting to detour on local streets, which are not designed for large traffic volumes.
   
• ADOT will be placing local-traffic-only closures at neighborhood entrances on a number of streets near I-17 to help keep detouring traffic off local roadways. Law enforcement officers will be stationed at intersections throughout the area to assist with traffic flow.

Crews are continuing a much-needed project to improve the ride on 6 miles of I-17 between Happy Valley Road and State Route 74. Additional I-17 closures or lane restrictions will be needed as the work proceeds. ADOT encourages drivers to sign up for project traffic alerts at azdot.gov/i-17HappyValleySR74.

Following the initial removal of an old, worn top layer of asphalt pavement along the freeway, crews are smoothing the freeway’s remaining concrete surface through a process called diamond grinding. Diamond grinding has been used in recent years to create a smoother and more durable road surface on a number of Phoenix-area freeways, including I-10, I-17, Loop 101 and Loop 202.

Future weekend restrictions for this project are currently scheduled as follows:

• Northbound I-17 narrowed to one lane between Loop 303 and SR 74/Carefree Highway from 9 p.m. Friday, Sept. 20, to 5 a.m. Monday, Sept. 23, and from 9 p.m. Friday, Sept. 27, to 5 a.m. Monday, Sept. 30.

Real-time highway conditions are available on ADOT’s Arizona Traveler Information site at az511.gov, the AZ511 app (download for Apple or Android devices) or by calling 511.

PHOENIX – Northbound Interstate 17 will be closed at Jomax Road in north Phoenix from 10 p.m. Friday to 5 a.m. Monday (Sept. 9) for ongoing pavement improvement work, according to the Arizona Department of Transportation. 

Traffic will detour along the northbound I-17 off- and on-ramps at Jomax Road. Northbound I-17 also will be narrowed to one lane between Jomax Road and Loop 303/Sonoran Desert Drive. 

Drivers should allow extra time, consider traveling during non-peak morning or nighttime hours and stay on the designated detour route.

Future weekend restrictions are currently scheduled as follows:

• Southbound I-17 closed at Loop 303 from 10 p.m. Friday, Sept. 13, to 5 a.m. Monday, Sept. 16. Traffic will detour along the off- and on-ramps at Loop 303. Southbound I-17 also narrowed to one lane between Loop 303 and Jomax Road.
• Northbound I-17 narrowed to one lane between Loop 303 and SR 74/Carefree Highway from 9 p.m. Friday, Sept. 20, to 5 a.m. Monday, Sept. 23.

Lengthy traffic backups are unavoidable during freeway closures like those required along I-17, so drivers should plan ahead. Those with weekend plans to use I-17 through the north Valley can consider traveling before closures begin on Friday nights. Traffic on I-17 also generally is lighter during the early morning hours or later at night and is expected to be especially busy by midday on Saturday and Sunday.

The I-17 pavement work between Happy Valley Road and SR 74 is separate from the I-17 Improvement Project currently underway north of Anthem Way. For more information about that larger project visit improvingi17.com. Drivers are reminded that the speed limit within that project’s work zone is 65 mph.

PHOENIX – Drivers planning to use northbound Interstate 17 in the north Valley this weekend should budget extra time. A pavement improvement project is taking traffic off and back on at Jomax Road and reducing the freeway to one lane until Loop 303/Sonoran Desert Drive.

The closure at Jomax Road using the off- and on-ramps and the lane restrictions are scheduled to begin at 10 p.m. Friday and end by 5 a.m. Monday, Aug. 12. Drivers should plan for delays, especially from morning to early afternoon Saturday and Sunday, and may want to consider traveling through the area earlier or later.

To help keep traffic moving through the work zone, Jomax Road will be closed at I-17 other than for northbound drivers exiting the freeway to turn right.

Crews are continuing a much-needed project to improve the ride on 6 miles of I-17 between Happy Valley Road and State Route 74.

PHOENIX – Drivers planning to use southbound Interstate 17 in the north Valley this weekend should budget extra time. Pavement improvement work is reducing the freeway down to one lane for three miles from State Route 74 (Carefree Highway) to Dixileta Drive. 

The lane restrictions are scheduled to begin at 9 p.m. Friday, July 19, and end by 5 a.m. Monday, July 22. Drivers should plan for delays, especially from afternoon into early evening on Saturday and Sunday, and may want to consider traveling through the area earlier or later. 

The work continues a much-needed project to improve the ride on six miles of I-17 between Happy Valley Road and SR 74. The project has already removed the top layer of older, worn asphalt pavement and crews will smooth the concrete surface through a process called diamond grinding and additional concrete work that requires extended time to cure. 

While there is no detour, ADOT encourages drivers to pack their patience, use caution and be prepared to slow down and merge safely as they travel on the highway through the three mile restriction. Staying on this route regardless of what a navigation app may suggest is the best way for drivers to reduce delays and avoid bringing unnecessary extra traffic in and around neighborhoods.
