PHOENIX – Drivers with plans to travel on northbound State Route 143 - and to Phoenix Sky Harbor International Airport from the East Valley - this weekend need to plan ahead for a full closure of the highway, according to the Arizona Department of Transportation. Crews with the Interstate 10 Broadway Curve Improvement Project are scheduled to set up work zones in anticipation of bridge construction.

Northbound SR 143 will be closed between I-10 and Washington Street from 10 p.m. Saturday, March 19, through 4 a.m. Monday, March 21. The following ramps will also be closed:

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

Detours: Multiple detours will be in place, and motorists should allow extra travel time. View detour video here. 

Drivers on westbound I-10 can exit onto eastbound US 60 (Superstition Freeway) and travel east to access northbound Loop 101 (Price Freeway). Drivers will continue north on Loop 101 to access westbound Loop 202 (Red Mountain Freeway). Drivers can also choose to exit onto eastbound Loop 202 (Santan Freeway) and travel east to access northbound Loop 101 (Price Freeway) to access westbound Loop 202 (Red Mountain Freeway). 

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 (Price Freeway). Drivers will continue north on Loop 101 to access westbound Loop 202 (Red Mountain Freeway).

Airport Traffic: From westbound I-10 exit at Buckeye Road, then follow signage into Phoenix Sky Harbor International Airport. Other drivers can use the airport exits from westbound Loop 202 (Red Mountain Freeway); or southbound SR143. Drivers heading to Phoenix Sky Harbor International Airport should allow extra travel time because delays are likely.

The I-10 Broadway Curve Improvement Project is identified in the Maricopa Association of Governments’ Regional Transportation Plan, funded by a half-cent sales tax approved by Maricopa County voters in 2004 through Proposition 400. MAG identified the need for this project 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.
