US 70: Medicine Way Passing Lane Project

Overview

The Arizona Department of Transportation anticipates beginning a project in early November 2025 to add a passing lane on eastbound US 70 between mileposts 274.5 and 275.5 within the San Carlos Apache Tribe community.

The project just east of Peridot will provide a 1-mile passing lane for faster moving eastbound traffic to overtake slower moving vehicles. Drainage improvements and other general maintenance work will also be completed within the project limits.
