State Route 189 Corridor Projects

   

State Route 189 (locally known as Mariposa Road) is a 3.75-mile long, ADOT-maintained highway in Nogales, Arizona. SR 189 runs from Interstate 19 to the US-Mexico Border.

ADOT is currently working on two separate improvement projects for the roadway:

In addition, ADOT and the City of Nogales are working to develop a pedestrian circulation plan for downtown Nogales and the vicinity of the Mariposa Land Port of Entry. For more information on that project, please visit the project site.

 


Your thoughts, opinions and ideas are important to ADOT. We encourage public participation and look forward to hearing from you by phone or email.
