In 1915, the State of Texas and the Daughters of the American Revolution (DAR) funded a project to place pink granite markers at approximately intervals along the route of the Old San Antonio Road. V.N. Zively, a professional surveyor, mapped the routing in 1915 and 1916 and placed an oak post at each marker site. Inscribed granite markers were installed later, and the Texas DAR presented the markers to the State of Texas in a ceremony in San Antonio on March 2, 1918.
