SR 90

There’s a smooth new asphalt surface on more than 20 miles of State Route 90 in Cochise County, including the stretch through Sierra Vista, thanks to an Arizona Department of Transportation project.

A small marker along State Route 90 shows where the Mormon Battalion fought is "Battle of the Bulls" during the Mexican-American War.

Three projects in Sierra Vista this summer

Public involvement truly helps shape ADOT projects … just ask residents living near the San Pedro River Bridge

The new interchange and realignment will feature wider entrance and exit ramps with traffic signals, overpass bridges that will provide for future growth, and a design that will accommodate a future project to add a westbound I-10 climbing lane starting at the Ocotillo Road exit east of SR 90.
