PHOENIX – Drivers who use Interstate 17 in north Phoenix are experiencing a much smoother ride following the Arizona Department of Transportation’s pavement improvement project that started in May 2024.

Major restrictions have ended along 6 miles of I-17 between Happy Valley Road and State Route 74 for the project to fix the outdated, rough freeway pavement. Crews last weekend installed final lane stripes on the improved riding surface.

After crews removed the old top layer of asphalt last year, the project used diamond grinding to improve the base concrete pavement. The treatment uses specialized machines with rotating drums containing diamond-tipped blades to smooth the concrete.

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.

The I-17 work north of Happy Valley Road followed another significant pavement improvement project between Dunlap Avenue and Deer Valley Road that was completed in September 2023.

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.

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.

HOLBROOK – The Arizona Department of Transportation will begin an improvement project on Business 40 from Crestview Drive and Joy Nevin Avenue in Holbrook starting Monday, Sept. 23.

Crews will be replacing the pavement and restriping the roadway as well as installing 24 Americans with Disabilities Act-compliant sidewalk ramps along the project area. 

B-40 (Navajo Boulevard) will be reduced to one lane in each direction as needed. Lane restrictions may also be required for sidewalk ramp work. Much of the work is anticipated to take place during daytime hours. Access to business will be maintained with minimal disruptions if/when project work requires.

Restrictions will be lifted each day after hours and on weekends. At least one lane of traffic will be open in each direction during paving. 

Drivers should allow extra travel time and be prepared to slow down, stay alert and merge safely when approaching and traveling through the work zones. 

This project is expected to be completed by the end of the year.

For more information, please visit the project webpage.

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.

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. 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.

ADOT offers these additional tips:

• 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-only closures at neighborhood entrances on a number of streets near I-17 to help direct detour traffic away from local roadways. Law enforcement officers will be stationed at intersections throughout the area to assist with traffic flow.
   
• Lengthy traffic backups are unavoidable during freeway closures like this one, so drivers should plan ahead. Those with weekend plans to use northbound I-17 through the north Valley can consider traveling before Friday night’s closure begins. Traffic on northbound I-17 also generally is lighter during the early morning hours or later at night and is expected to be especially busy on Saturday and Sunday afternoons.

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.
