The Arizona Department of Transportation (ADOT) and the Federal Highway Administration (FHWA) have initiated a project to widen Interstate 10 between Casa Grande and Tucson, from just south of Earley Road to Interstate 8 (mileposts 196-200) in Casa Grande. Work began in March 2018 and is scheduled for completion in fall 2019.

The project will add one lane in each direction adjacent to the median, with a concrete barrier separating directions of travel, and replaces the existing bridge over Jimmie Kerr Boulevard and the Union Pacific Railroad. The project includes installation of a fiber optic trunk line between milepost 186 and milepost 209.

The completed project will increase freeway capacity, improve auxiliary lanes and enhance aesthetics of the new roadway.
