The destination signing should identify the city name or the type of crossing or both. If a city name is used without specifying the type of crossing, it implies that the crossing is an international crossing.

Destination signing for Mexican border cities should indicate the city names, but

not

the country name “Mexico,” except when necessary to prevent confusion.

Smaller cities with crossings should have destination and any necessary mileage signs at the nearest intersecting highway for the crossing roadway.

Where a Texas city is adjacent to a Mexican city, it may be desirable to sign both cities. For example, Eagle Pass and Piedras Negras might appear on the same sign because both cities are of similar importance.
