Eloy’s new interchange at Interstate 10 and State Route 87 is taking shape. Arizona Department of Transportation crews placed 45,000-lb. girders that will form the deck of the SR 87 bridge, according to an ADOT press release.

“The new interchange will be located just north of the current alignment of SR 87 and will carry the road over the Union Pacific Railroad tracks as well as new lanes of I-10 to connect with Phillips Road on the other side of the freeway,” stated the release.

The work is part of a project to make I-10 traffic flow more safely in Pinal County. Crews are building four miles of new interstate lanes that will widen I-10 in the area to six lanes between mileposts 209 and 213.

ADOT reports that “This fall, crews will begin creating a first-of-its-kind dust detection zone designed to identify dust storms in the area and provide drivers with information to make safe decisions.”

A second ADOT team is widening I-10 to six lanes north of Interstate 8 in Casa Grande, including new bridges and a new interchange at Jimmie Kerr Boulevard. When both projects are completed by late summer or early fall in 2019, I-10 will be a six-lane freeway from Casa Grande to Tucson.

STATEWIDE ROAD PROJECTS – Approved for 2019-2023

“A major freight corridor in Southern Arizona that moves trucks to and from Mexico for produce and other goods will undergo a full build-out of improvements over the next few years,” according to an Arizona Department of Transportation press release.

Other major expansion projects along key commerce corridors including Interstate 17 and US 93, along with SR 260, were also approved by the state transportation board as part of the annual update to the Arizona Department of Transportation’s Five-Year Transportation Facilities Construction Program.

“ADOT’s mission is to provide reliable infrastructure to help move people, goods and services, generate commerce and economic activity, and connect major freight and travel corridors,” ADOT Director John Halikowski said.
