During the 1920s San Antonio's Gunter Hotel was the headquarters for the building of the southern U.S. transcontinental Auto Highway commemorated by the 0-Mile Stone on City Hall lawn. From St. Augustine, Florida to San Diego, California, the Old Spanish Trail links cities of Spanish conquest and settlement. The OST enters San Antonio on Seguin St. along I-35, proceeds south on New Braunfels Ave. to Houston St., west on Houston to Flores St., north along Flores and out Fredericksburg Rd., I-10 and Boerne Stage Rd. into the hill country. A decorative stone bench recognizing the OST is located at 3400 Fredericksburg Rd. To see a map, click on
