A block later, bear right. Most of the development you see in the background is in Mexico; we’re only a couple blocks from the border. The freeway begins a block after we head around this corner

As we head around the corner, we’re presented with the most metricated highway in the USA, I-19. Mileposts are in kilometers (hence AKP), and distance is mostly in meters and kilometers. Speed limits are still in Imperial units, however

1500 meters after the freeway begins, we’ll get 2 km notification for SR 189, which heads south. It’s the main truck route to Mexico and the fastest route to Hermosillo and places that aren’t Nogales

Exit for SR 189 south, which heads directly to Mexico’s Carretera Federal 15.
