Construction Updates
Drivers will notice a new traffic configuration on I-10 just north of Casa Grande. Crews shifted the existing two lanes of traffic to the outside lanes on eastbound and westbound I‑10 between Dirk Lay Road Bridge and SR 387/Pinal Ave. (Mileposts 177-187).
These shifts will allow crews to begin constructing a third general‑purpose lane in the median. This traffic configuration will remain in place for about one year.
