Largest Freeway Rebuild in ADOT History to Wrap by December

March 21, 2024|


CHANDLER, Ariz. – The largest freeway reconstruction project in Arizona Dept. of Transportation history is proceeding on schedule for completion near the end of 2024.

Construction on the massive, $1 billion-plus widening of a 26-mile stretch of Interstate 10 between Phoenix and Tucson began in Fall 2021 and is slated to reach an on-time finish late this year.

Funding for the work – which includes reconstruction of bridges over the Gila River and construction of six new interchanges along I-10 – has come from multiple levels of government: $96 million in federal funds, $700 million from the state of Arizona and $200 million from the Maricopa Association of Governments.

The interstate segment stretches through the Gila River Indian Community.

When the project concludes, I-10 will carry traffic on three lanes in both directions.
