Interstate 10/Koli Road Traffic Interchange Study

*Previously known as the Interstate 10 (I-10) Germann Road Traffic Interchange Study

The Arizona Department of Transportation (ADOT), as the lead agency and project sponsor, in collaboration with the Gila River Indian Community (Community), the Bureau of Indian Affairs (BIA), the Federal Highway Administration (FHWA) and the Maricopa Association of Governments, has initiated a Design Concept Report (DCR) and an environmental study (assumed to be an Environmental Assessment or EA) for the proposed Interstate 10/Koli Road Traffic Interchange.

The proposed I-10/Koli Road Traffic Interchange would be located on I-10 between the existing Wild Horse Pass Boulevard and State Route 347/Queen Creek Road traffic interchanges.

The study area limits extend approximately a half mile from each side of the I-10 center line to Maricopa Road and approximately three-quarters of a mile north of milepost 163 and 1.8 miles south of milepost 163 along I-10. The project is located in Maricopa County and entirely within the Gila River Indian Community.

The Environmental Assessment (EA) will consider and assess alternatives for the traffic interchange, including a no-build alternative. Some considerations to be analyzed in-depth in the EA will include the proposed project’s impacts on cultural resources, biological resources, water quality, recreational resources, noise impacts and air quality, as well as other social, economic, and environmental impacts.

Public scoping is the first step of the National Environmental Policy Act (NEPA) environmental study process. The public scoping and alternatives process provides the opportunity for the Community to educate the study team about the I-10/Koli Road Traffic Interchange study area, as well as share concerns about modifying I-10 to incorporate a traffic interchange at approximately Koli Road.

• Provide an overview of the I-10/Koli Road Traffic Interchange study area, the study’s objectives, and the study’s schedule
• Obtain feedback on opportunities, issues, and concerns related to the study area
• Solicit input on potential study area improvement alternatives

 This input will help ADOT, the Community, and MAG select a Preferred Alternative for this section of I-10 and Koli Road.

ADOT hosted the Virtual I-10/Koli Road Traffic Interchange Study Scoping and Alternative Public Meeting on Tuesday, October 8.
