PHOENIX — Arizona is launching a highway-improvement project to speed the flow of truck traffic that crosses the U.S. border at Nogales, Arizona. The project includes building new flyover ramps to connect Interstate 19 on the northern outskirts of Nogales with State Route 189, a highway that serves the Mariposa Port of Entry on Nogales’ west side.
Federal, state and local officials participated in a ceremonial groundbreaking March 4, and the Arizona state Department of Transportation (ADOT) said construction should start in April.
The department said the upgrades to SR 189 will eliminate the current need for trucks to stop up to three times between I-19 and the border. According to the department, up to 1,800 commercial trucks use SR 189 daily during the winter months. That’s when large produce shipments head northward from Mexico.
According to ADOT, construction is expected to take about 18 months to complete. Initial funding for the project includes a $25 million state appropriation and a $25 million federal grant. ADOT predicts that the project will benefit Nogales residents and businesses by reducing congestion.
Along with the flyover ramps, the project also includes a new roundabout and improved drainage and traffic signals.
