New Pedestrian Underpass Planned For Mariposa Port

The Arizona Department of Transportation is building a new pedestrian underpass on State Route 189 (Mariposa Road) that will allow pedestrians to travel to and from the Mariposa Port of Entry in Nogales.

Traffic on State Route 189 (Mariposa Road) will be stopped intermittently at the Mariposa Port of Entry in Nogales on Wednesday, July 15, and Thursday, July 16, from 6 a.m. to 4:30 p.m. for survey activities.

Currently, there is no separation between commercial truck and pedestrian traffic at the port of entry within the state right-of-way. The highway serves as a bypass route for truck traffic to and from Mexico.

ADOT will construct a 356-foot-long, 10-by-10 concrete box culvert underneath SR 189 that will include ventilation structures and lighting. Other improvements include new sidewalks, traffic signals and storm drain improvements.

At less than four miles long, SR 189 in Nogales is one of the shortest routes on the state’s highway system.

The $3.3 million improvement project is expected to be completed in December 2015.
