This is an alternate exit to take off of Avenida Internacional (aka Vía Internacional or just Internacional) if the border line is long and the exit near the Smart & Final/Mexitlán (Av. Melchor Ocampo) is closed. Or if Avenida Internacional is backed up, this is a quicker way to get to Calle Segunda/the border line. (However this exit is before the exit near the Smart & Final/Mexitlán which is more direct, therefore you would have to make a decision to take it possibly without knowing if that exit is closed.)
If the border line is really long, this way is sometimes blocked off by authorities as well. (See note at bottom of the page). Although this is the exit for Avenida Revolución, this route does not actually take Avenida Revolución, but will cross it.

*If before getting to Calle Segunda this way is blocked off by authorities, they usually direct
traffic to take a right at the second Alto. This means the traffic will flow parallel to
Calle Segunda/the border line. At the first opportunity, take a left heading towards Calle
Segunda, then a left onto Calle Segunda.
