PHOENIX – The Arizona Department of Transportation has reopened US 160 east of Kayenta after making critical repairs to a flood-damaged portion of the highway. 

Crews worked over the past week, including through the weekend, on drainage improvements, roadway reconstruction, new pavement and asphalt, and new striping for approximately 80 feet of damaged roadway near Dennehotso. 

ADOT has begun critical repair work on US 160 near Dennehotso after the roadway sustained significant damage from storms on Sept. 16.

A pavement improvement project along State Route 260 between Linden and Show Low will begin Tuesday, July 7.

The $3.9 million project removed and replaced the road surface between mileposts 29 and 31, beginning just south of State Route 82. It also installed fog coating, added new pavement markings and signage, replaced guardrails and upgraded drainage.

The pavement rehabilitation project, which began last August, milled and replaced the existing pavement with new pavement between mileposts 20 and 30. In addition to new guardrails and end terminals, crews installed new fencing, signage and pavement markings, among other upgrades. 

This week’s episode of On the Road With ADOT features two of our many team members involved in preserving Arizona’s vast investment in state highways and the use of fog seals to extend pavement life.

The $2.1 million project, which began in September 2024, improved a route commonly known as Navajo Boulevard in downtown Holbrook, which is home to dozens of businesses. Other improvements included ADA-compliant sidewalk ramps.

The $19 million project milled the highway surface and replaced it with new pavement between mile markers 80-90, a stretch that begins about 20 miles west of SR 85. The project also added drainage, replaced guardrails, and repaired a bridge and box culverts. 

The pavement rehabilitation project, which began in August, applied chip seal and micro surface treatments between State Route 77 near Holbrook and milepost 13 northeast of State Route 277 and Heber-Overgaard. It also made spot pavement repairs.

This $30 million improvement near Petrified Forest National Park removed the top layer of pavement between mileposts 319 and 331 and replaced it with an asphalt-mix overlay. Crews also replaced the eastbound I-40 Dead River Bridge deck to extend the structure’s life and enhance safety.

This chip seal and slurry seal project is another way ADOT works to safely connect people and empower the economy across Arizona. The project also supports ADOT’s commitment to protecting Arizona’s investment in highway pavement and bridges. 

Resident Engineer Joe Heller has all the details on a project rehabilitating the I-17 pavement between SR 74 and Anthem Way, including the good news that the freeway itself will only see overnight and weekend lane restrictions. That means no planned closures. 

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.

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 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. 

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. 

The closure at Jomax Road and 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.

Pavement improvement work is reducing the freeway down to one lane for three miles from State Route 74 (Carefree Highway) to Dixileta Drive. 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 lane restrictions and the closure at Jomax Road, with traffic using the off- and on-ramps, are scheduled to begin at 9 p.m. Friday and end by 5 a.m. Monday, July 15. Drivers should plan for delays and may want to travel through earlier or later than the late afternoon traffic peak.

Continuing a much-needed project to improve the ride on 6 miles of I-17 between Happy Valley Road and SR 74, crews removed a top layer of older, worn asphalt pavement before advancing to work to smooth the remaining concrete surface through a process called diamond grinding.
