TIB -vehicle via Laredo TX

Hi everyone! Does anyone know if a chassis truck vehicle can cross the World Trade Bridge (Laredo, TX) under its own power as a TIB? (Northbound) One officer told me, “Sure, no problem,” but then another one denied it and said we have to go through Colombia, TX.

So now I’m totally lost. Does anyone have experience at this port? I’d really appreciate your help!
