Reminder: Northbound I-17 closed this weekend in north Phoenix

Freeway will be closed between Loop 303 and SR 74 for pavement project

PHOENIX - A weekend closure of northbound I-17 in north Phoenix is scheduled Feb. 7-10 for pavement improvement work near Loop 303, according to the Arizona Department of Transportation.

ADOT has scheduled four weekend closures for final bridge and pavement improvements, including this one:

• Northbound I-17 closed between Loop 303 and SR 74/Carefree Highway from 10 p.m. Friday, Feb. 7, to 5 a.m. Monday, Feb. 10. Eastbound Loop 303 traffic at I-17 will be limited to a right turn onto southbound I-17 (no traffic crossing under I-17). DETOUR: Allow extra travel time. Northbound I-17 traffic exiting at Loop 303 will detour on the northbound frontage road to SR 74 to reach I-17. Note: To limit delays for you and others use the frontage road detour, even if a navigation app suggests another route. Avoid using local streets east of I-17 that are not designed to handle freeway traffic. Some street closures will be in place (local traffic only). Eastbound Jomax Road and Dixileta Drive closed at the southbound I-17 frontage road. Also Note: Access to the city of Phoenix's Waste Transfer Station will be maintained via Dixileta Drive (allow extra travel time).
• Eastbound Loop 303 and westbound Sonoran Desert Drive traffic will not be able to travel under I-17 this weekend(10 p.m. Friday to 5 a.m. Monday, Feb. 10) while northbound I-17 is closed. DETOURS: Drivers on eastbound Loop 303 can access northbound I-17by traveling north on 43rd Avenue to eastbound Dove Valley Road and continuing to SR 74 on the northbound I-17 frontage road. Detour routesfor drivers who normally would use westbound Sonoran Desert Drive to I-17include southbound North Valley Parkway to westbound Jomax Road.

The much-needed project to improve the pavement along I-17 between Happy Valley Road and State Route 74 has removed the old, worn top layer of asphalt pavement, and the concrete pavement beneath it has undergone a treatment known as diamond grinding. The current schedule calls for three additional weekend closures:

• Southbound I-17 closed between Loop 303 and Happy Valley Road from 10 p.m. Friday, Feb. 14, to 5 a.m. Monday, Feb. 17.
• Northbound I-17 closed between Happy Valley Road and Loop 303 from 10 p.m. Friday, Feb. 21, to 5 a.m. Monday, Feb. 24.
• Southbound I-17 closed between SR 74/Carefree Highway and Loop 303 from 10 p.m. Friday, Feb. 28, to 5 a.m. Monday, March 3.

The closure schedule is subject to change due to inclement weather or other factors. The improvement work already has created a safer, smoother and longer lasting surface along 6 miles of I-17 north of Happy Valley Road. Work on the project started in May 2024.
