I-10 project map

The Arizona Department of Transportation has begun a $15 million project between state routes 587 and 387.

CASA GRANDE — Overnight drivers on Interstate 10 in the Gila River Indian Community and Pinal County should expect delays caused by a project expected to last the rest of the year.

The Arizona Department of Transportation announced Monday that it has commenced on a $15 million project taking place on a 10-mile stretch of I-10 between State Route 587 (Casa Blanca Road) and State Route 387 near Casa Grande.

The project will be completed in two-mile increments. Between 8 p.m. and 5 a.m. Sundays through Thursdays, travel in both directions will be limited to one lane for those two miles.

ADOT is advising drivers to expect 20-minute delays and to slow down and use extreme caution as the work sites will be adjacent to the travel lanes.

During the course of the project, crews will be removing and replacing pavement in both directions, installing new guardrails, signing, striping and seeding the highway, among other work. The pavement will be resurfaced with rubberized asphalt.
