Common questions about this lane

How do I find carriers for Detroit to San Luis Potosí?

On Cargado, brokers post the corridor and vetted carriers bid on it. Every carrier is verified before it can bid, which replaces cold-calling unknown carriers.

What equipment is available on the Detroit to San Luis Potosí corridor?

Postings here are mostly dry van, with some open-deck and straight truck. If you need a type you do not see, post the load anyway. Carriers with matching equipment get notified automatically.

Does freight on this corridor transload at the border or run direct?

Both happen. Most freight crosses at Laredo (World Trade Bridge), where carriers either transfer the trailer to a cross-border drayage carrier or run direct with a through-trailer. The bid reflects the carrier's setup.
