The Arizona Department of Transportation advises motorists to allow extra travel time and plan to use detours while northbound SR 143 is closed between Interstate 10 and University Drive from 10 p.m. Friday, Nov. 4, to 4 a.m. Monday, Nov. 7. Crews with the I-10 Broadway Curve Improvement Project are establishing a new work zone.

At the same time, the following ramps and local streets will be closed:

  • The westbound I-10 ramp to northbound SR 143.
  • Northbound 48th Street between Broadway Road and I-10.

Westbound I-10 to northbound SR 143 detour: Use westbound I-10 to eastbound Loop 202 (Red Mountain Freeway) to access SR 143 and other destinations north of the closure.

Eastbound I-10 to northbound SR 143 detour: Use Broadway Road to northbound Priest Drive, to westbound University Drive to access SR 143 and other destinations north of the closure.

Airport traffic: Motorists on westbound I-10 and westbound US 60 heading to Phoenix Sky Harbor International Airport should use westbound I-10 to the airport entrances at 24th Street or Buckeye Road, or use the Sky Harbor Boulevard entrance from the Loop 202 (Red Mountain Freeway).

Temporary configuration: When northbound SR 143 reopens on Monday, Nov. 7, drivers will use temporary travel lanes until mid-2023. The existing northbound SR 143 roadway between I-10 and University Drive will be closed.
