Military and civilian supplies were transported back by wagon trains, and they were subsequently railroaded to the other Confederate states.

The Colorado River was crossed following the war, and the railroad was extended to Columbus, the county seat, and other western locations.

During the first part of the 20th century, Alleyton's main agricultural products were cotton, with minor emphasis on rice, corn, and pecans.

Large-scale strip mining activities along the river that removed gravel caused the construction of numerous lakes that are famous fishing spots in the area as well as the destruction of some productive farming and grazing land.

During the 1950s, Alleyton's population had dropped to about 125 due to the growing usage of synthetic clothing during the post-World War II era and more government regulation of cotton production.
