The Arizona Department of Transportation (ADOT) has announced the opening of newly constructed travel lanes on Interstate 10 in the Broadway Curve area. These additional lanes are now accessible to motorists traveling both eastbound and westbound.

On the eastbound I-10 mainline, the new lanes extend from I-17 near Phoenix Sky Harbor Airport to Baseline Road. Westbound travelers will find new lanes between US 60 and 32nd Street.

A key part of the I-10 Broadway Curve Improvement Project involved expanding I-10 from four to six travel lanes and adding a high occupancy vehicle (HOV) lane, increasing the total number of HOV lanes to two in each direction through this area. These HOV lanes are expected to open in March.

In addition, March will see the completion of work on the interchange between I-10 and SR 143, including new HOV flyover ramps connecting these routes.

Previously, last summer and fall marked the construction of Collector Distributor (CD) Roads along I-10 in both directions within the Broadway Curve area. These roads separate mainline traffic from vehicles entering or exiting the freeway, representing another significant component of this project.

The full completion of the I-10 Broadway Curve Improvement Project is anticipated by spring 2025.

ADOT advises drivers to use designated detours during any state highway closures. Schedules may change due to weather or unforeseen circumstances. For updates, drivers can download TheCurve mobile app or visit the project's website for alerts before traveling.

The project is part of Maricopa Association of Governments’ Regional Transportation Plan and funded by a half-cent sales tax approved by Maricopa County voters in 2004 through Proposition 400. The plan aims to reduce peak-hour travel times on I-10, improve airport access, support ridesharing and transit options, and prepare for future regional growth projections.
