The girders are in place and flyover ramps are taking shape at the SR 189 (Mariposa Road) interchange with Interstate 19 in Nogales. The $134 million project by the Arizona Department of Transportation will reduce wait times for the throng of trucks and vehicles entering I-19 from the Mariposa Port of Entry. It also includes widening 3 miles of SR 189 from north of the Mariposa Port of Entry to the intersection with Grand Avenue and a new roundabout at SR 189 and Target Range Road. Completion is set for Fall, 2021. Video by Kelly Presnell / Arizona Daily Star
