Public meeting will preview potential I-10 improvements in metro Phoenix

Proposed ADOT upgrade covers 11 miles including Broadway Curve
February 11, 2019

PHOENIX – The Arizona Department of Transportation will hold a meeting in Tempe on Tuesday, Feb. 26, allowing the public to get information and provide input on improvements proposed for Interstate 10 between the Interstate 17 “Split” interchange and the Loop 202 Santan Freeway crossing Phoenix, Tempe, Guadalupe and Chandler.I-10 Broadway Curve Study Map

The I-10 Broadway Curve Study includes widening and upgrading 11 miles of I-10 between 24th Street and Ray Road, including the Broadway Curve, which handles more than 40 percent of freeway traffic in the region, resulting in heavy congestion.

The project must first go through an Environmental Assessment to analyze potential impacts of the proposed improvements. 

Major elements of the potential project include the addition of a second HOV lane in each direction between the Salt River bridges and just west of US 60; a new collector-distributor roadway system that would funnel traffic to local and express lanes to improve traffic flow; reconstruction of the I-10/State Route 143 interchange to improve access to and from Phoenix Sky Harbor International Airport; and improving US 60 near the junction with I-10.

ADOT and the Federal Highway Administration invite the public to attend an open house meeting:

When: 5:30 p.m. to 7:30 p.m. Tuesday, Feb. 26

Where: Rio Salado College Conference Center, 2323 W. 14th St., Tempe, AZ 85281

Who: Representatives from ADOT’s I-10 Broadway Curve Study Team will be available to hear comments and answer questions. There will be a brief presentation at 6 p.m.

Funding for the potential project is allocated through the Maricopa Association of Governments’ Regional Transportation Plan approved by county voters in 2004.

Construction could begin in early 2021.

Beyond the public meeting, opportunities to learn more about the project and provide feedback are available:

· Online:

· Mail: ADOT Communications, 1655 W. Jackson St., MD 126F, Phoenix AZ 85007

· Email:

Comments must be received by April 1 to be considered part of the scoping process for the I-10 Broadway Curve Study.
