The building has remained in continuous operation as a post office since 1907. However, in the 1950s, the growing economy forced the Bank of Mexico next door to occupy a large section of the Palacio de Correos, for this reason, two bridges were built to connect the Palacio with the Bank of Mexico building. Modifications for the Bank destroyed much of the decoration elements that were originally in this section. They also added greatly to the weight of the building and have overloaded the steel structure. This would cause damage to the building, along with the 1985 Mexico City earthquake.
