Maricopa County is in the midst of its largest urban freeway reconstruction project. The Arizona Department of Transportation (ADOT) is reconstructing Interstate 10 (I-10) between Loop 202 and Interstate 17 (I-17), transforming over 11 miles of interstate. This project includes several improvements that will enhance safety, reduce travel time, ease access to Phoenix Sky Harbor International Airport, and support the local economies, but Phoenix drivers can expect changes to freeway accessibility as construction begins.

Read our blog post below and learn what the I-10 Broadway Curve widening project means for transportation in the Phoenix metropolitan area.
Why ADOT is Prioritizing the Broadway Curve Widening
These improvements have been underway since early 2019 when ADOT began an environmental assessment of the area. However, the project recently achieved a major milestone, as ADOT issued a formal notice to begin construction. ADOT Director John Halikowski said, “delivering this project after years of study and careful consideration of public input demonstrates ADOT’s commitment to providing the safest, most reliable transportation system in the nation.”
ADOT believes these improvements will benefit everyone who relies on the highway system. Millions of people who live in, work in, and visit Arizona every year could see a better flow of traffic and less congestion in transportation routes. These improvements also support Arizona’s global trade market efforts, as I-10 is a key commerce corridor.
The Infrastructure of the Broadway Curve Widening Project
Over 300,000 vehicles travel through the Broadway Curve on a daily basis, and traffic is anticipated to increase as the Phoenix metropolitan area continues to grow. The project will support traffic flow by addressing key improvements, such as:
- Adding lanes to achieve six general-purpose lanes and two HOV lanes from 24th Street to US 60 Superstition Freeway.
- Connect the main travel lanes of the highway to frontage roads or entrance ramps between Baseline Road and 40th Street, with a collector-distributor road system, to separate local traffic from through traffic on I-10.
- Creating a fourth general-purpose lane on I-10 from US 60 to Ray Road
- Improving I-10 connections at SR 143, Broadway Road, and US 60 for better traffic flow and safety.
- Replacing ramps and bridges at SR 143 and US 60 interchanges.
- Adding two bridges over I-10 between Baseline Road and Broadway Road for pedestrians and bicyclists.
- Improving the Sun Circle Trail crossing at Guadalupe Road.
What Arizonans Can Expect From the Broadway Curve Widening Project
As work on these various projects continues, Arizonans can expect to see construction activity to have some impact on travel. Construction will continue through 2024 in various areas.
Arizonans can get updates and information about the I-10 Broadway Curve Improvement Project through The Curve mobile app. Through this app, ADOT plans to update drivers in the project area about closures and restrictions, real-time traffic information, detour routes, and more.
