PM me if you are in the Zacatecas area.
If you're heading south, use the Pharr bridge. The bypass is open, 7 pesos will dump you out on 97, just north of the aduana checkpoint. Just cross the bridge and keep going straight south. Don't get off at the highway intersection.
If you're headed towards Monterrey, Anzalduas will keep you out of traffic, but there's no convenient money exchange places. There is one at the Soriana opposite the highway intersection, but their rates aren't great.
