Welcome to the OST100 website.
OST100 has been organized
to locate, revitalize and preserve
the roadway, businesses and historic sites of the
original 1920s OLD SPANISH TRAIL auto highway
for a decade long Centennial Celebration
with a 2029 motorcade grand finale from
St. Augustine, Florida to San Diego, California.
Late registrations will be accepted up to November 1st.
San Antonio was the center of the 1920s OST Association. We in San Antonio and Bexar County, Texas began centennial preparations by working on the original 32-mile "OST Headquarters Section."
This website has areas where the 67 counties across the OST can find ideas for using maps and oral histories to locate the roadbed, public and private funding to revitalize the businesses, and sound conservation practices to preserve OST sites.
We have posted annual travel logs and newspaper and magazine articles of the founding 1920s OST Association.
Success stories from other OST counties are also posted here as historic, conservation, and development societies and agencies revitalize each section.
The business and political partnerships formed in the early days to build and beautify the OST will again work to revitalize and beautify the scenic original OST roadbed that can become a pleasant alternative to Interstate-10 for travelers interested in recapturing the historic ambiance of the gulf and southern border states.
