UPDATE: I-17 lane and ramp closures planned for Sept. 16 - 19

This advisory updates the planned weekend restrictions; narrowing between Dunlap Avenue and Thunderbird Road has been postponed.

Drivers who use Interstate 17 in the Phoenix area should allow extra travel time and consider alternate routes while the following weekend restrictions are in place for pavement removal.

  • Northbound I-17 between Thunderbird Road and Yorkshire Drive will be closed from 10 p.m. Friday, Sept. 16, to 5 a.m. Monday, Sept. 19. 
  • The following ramps also will be closed:
    • The northbound I-17 on-ramps at Northern, Dunlap, and Peoria avenues, and Cactus, Thunderbird, Greenway and Bell roads.
    • DETOUR: Motorists may consider exiting ahead of the closure and using 19th and 35th avenues to Deer Valley Rd to connect with I-17 beyond the closure. Motorists may also use alternate routes including northbound SR 51 or Loop 101 (West Valley) to avoid heavy backups along I-17. 
  • UPDATED: The north- and southbound I-17 narrowing between Dunlap Avenue and Thunderbird Road has been postponed. 

Drivers should use caution and be prepared to slow down and merge safely when approaching and traveling through any work zones.
