I’ve crossed vía the west crossing several times in the last couple months, standard lanes and on Sunday vía Sentri lane for the first time. If
you hit the border fence just east of the crossing, ie coming from the east crossing, and turn west, it will put you in line for both regular and
Sentri.
When you get close stay left and the first indication I saw was a medical lane sign, follow that. Right there the road becomes divided by a concrete
barrier. Stay left of the barrier and you’re in the Sentri lanes. If you stay right along the fence I don’t believe there is any way to get into
the Sentri lanes from there. |
