Improvement projects will require closures or lane restrictions along a pair of freeways near downtown Phoenix this weekend (Dec. 8-11). The Arizona Department of Transportation has scheduled mostly overnight closures of Interstate 10 for cleaning and maintenance of the Deck Park Tunnel. A section of southbound Interstate 17 near Seventh Avenue will be narrowed starting Friday night for bridge repair work. Drivers should allow extra travel time and consider alternate routes if necessary while the following restrictions are in place:

  • Westbound Interstate 10 closed between the I-17 “Split” interchange near Sky Harbor Airport and Seventh Avenue from 9 p.m. Friday to 9 a.m. Saturday (Dec. 9) for tunnel cleaning and maintenance. Southbound SR 51 ramp to westbound I-10 closed. Westbound I-10 on-ramp for Sky Harbor Circle and Washington Street restricted with only access to northbound SR 51 and eastbound Loop 202. Westbound Loop 202 ramp to westbound I-10 will be open but all traffic must exit at Seventh Street and use detour routes, including McDowell Road. Southbound I-17 ramp to westbound I-10 near Sky Harbor Airport closed. DETOUR: Allow extra travel time. Westbound I-10 traffic approaching the closure near the airport can detour to northbound I-17 and can reconnect with I-10 at the “Stack” interchange.
  • Eastbound Interstate 10 closed between the I-17 “Stack” interchange and the Washington/Jefferson streets interchange near Sky Harbor Airport from 9 p.m. Saturday to 9 a.m. Sunday (Dec. 10) for tunnel cleaning and maintenance. Both I-17 ramps to eastbound I-10 at the Stack closed. DETOUR: Allow extra travel time and consider alternate routes. Eastbound I-10 traffic can detour to southbound I-17 starting at the Stack.
  • Southbound I-17 narrowed to two lanes near Seventh Avenue (south of downtown Phoenix) from 9 p.m. Friday to 5 a.m. Monday (Dec. 11) for bridge work. Seventh Avenue closed in both directions at I-17. I-17 traffic exiting at Seventh Avenue will not be able to make left turns onto Seventh Avenue. DETOUR: Allow extra travel time and consider alternate routes, including eastbound Interstate 10 in the downtown area. Alternate routes while Seventh Avenue is closed include Central Avenue, 19th Avenue or Seventh Street. NOTE: Southbound I-17 near Seventh Avenue will temporarily be narrowed to one lane Friday night for barrier wall set up and prior to the end of this weekend’s work for a barrier wall shift.

Real-time highway conditions are available on ADOT’s Arizona Traveler Information site at, by calling 511 and through ADOT’s Twitter feed, @ArizonaDOT. When a freeway closure or other major traffic event occurs, our free app available at will send critical information directly to app users in affected areas – where possible, in advance of alternate routes.

Additional freeway-restriction information will be posted at, under ADOT News. Visit the site to also subscribe to ADOT email updates, including weekend restriction information.

ADOT plans and constructs new freeways, additional lanes and other improvements as part of the Regional Transportation Plan for the Maricopa County region. The primary funding source for regional freeway improvements is a half-cent sales tax approved by county voters in 2004. More information about ADOT projects and the regional plan is available at
