PHOENIX – An Arizona Department of Transportation project that will speed up international commerce, boost the economy and make Nogales traffic safer has begun near Arizona’s southern border.
To make way for improvements to State Route 189 (Mariposa Road) in Nogales, the 3.75-mile road that connects the international border with Interstate 19, crews have been clearing brush from the path of the first of two flyover ramps that will connect northbound SR 189 with northbound I-19. Construction is scheduled to start in earnest next week and take about 18 months.
