The international bridges in this region, also known as "The White Border", deserve a special mention due to the marked absence of social problems, generally present in the border cities.

Piedras Negras has two international vehicular bridges and one international railroad bridge:

• Eagle Pass-Piedras Negras International Bridge (formerly known as General Carlos Pacheco): It is 565 m long and 11 m wide.

• Camino Real International Bridge (also known as Coahuila 2000 or Camino Real): This bridge connects Piedras Negras with Eagle Pass and has been qualified by the U.S.
