The state is looking for ideas to improve the Riggs Road traffic interchange at State Route 347.

The Arizona Department of Transportation has launched a study on traffic flow and safety in the area and is asking for the public’s help on possible options.

ADOT officials said they are evaluating a range of interchange alternatives to separate traffic on the two roadways on a new bridge.

Options are detailed on the study website at tinyurl.com/riggsrdsr347.

ADOT is conducting the study in partnership with the Gila River Indian Community and the Maricopa Association of Governments, and in coordination with the Bureau of Indian Affairs.

The study is expected to continue through summer of 2025, according to ADOT, and it will identify the preferred alternative in a Design Concept Report and environmental document.

If a new-build alternative is selected, the project is anticipated to advertise for construction in late 2025.

There will be additional opportunities to provide input, including public meetings, as the project progresses, transportation officials said.
