Traffic delays around Sky Harbor this weekend 


The Arizona Department of Transportation will close State Route 143, the Hohokam Expressway, which leads to Sky Harbor International Airport, this weekend. 

In a news release, ADOT stated that northbound SR 143 between Interstate 10 and Washington Street will close this weekend, March 19-21. 

“Drivers with plans to travel on northbound SR 143 – and to Phoenix Sky Harbor International Airport from the East Valley – need to plan ahead for a full closure of the highway. Crews with the Interstate 10 Broadway Curve Improvement Project are scheduled to set up work zones in anticipation of bridge construction.” 

ADOT said northbound SR 143 will be closed between I-10 and Washington Street from 10 p.m. Saturday through 4 a.m. Monday. In addition, two ramps will be closed:  

  • The ramp from westbound I-10 to northbound SR 143. 
  • The on-ramps to northbound SR 143 from University Drive and 48th Street. 

Detours recommended by ADOT for drivers traveling to Sky Harbor from Maricopa via I-10 include taking eastbound US 60 (Superstition Freeway) east to the northbound Loop 101 (Price Freeway) and continuing north on Loop 101 to westbound Loop 202 (Red Mountain Freeway) which provides airport access.  

An alternate detour would be to exit westbound I-10 onto the eastbound Loop 202 (Santan Freeway) and travel east to access northbound Loop 101 (Price Freeway) to access westbound Loop 202 (Red Mountain Freeway) and the airport.  

Drivers on eastbound I-10 can exit onto US 60 (Superstition Freeway) after the closure. From the US 60, drivers will travel east to access northbound Loop 101, then continue north on Loop 101 to Loop 202 westbound into Sky Harbor. 

ADOT offers a free mobile app, The Curve, that provides real-time traffic information and updates. 

The I-10 Broadway Curve Improvement Project was identified by the Maricopa Association of Governments as necessary to reduce travel times on I-10 during peak hours; improve airport access; support ridesharing and transit; and prepare the region for future growth projections.
