The City of Dayton is proud to be an official Old Spanish Trail City.

To commemorate the project, the City of Dayton holds an annual motorcade of antique and classic vehicles. Vehicles will travel from the Community Center to Liberty and back via Hwy 90, which was originally the OST. Upon returning to the Community Center, the vehicles will be on display, along with food trucks and music, making for a family-friendly event.

“We’re pleased to join the other cities along the route in celebrating the Anniversary of this historic highway. Its creation came from a great vision, and we’re proud that Dayton played a part in making cross-country travel possible for the average person.”

Mayor Caroline Wadzeck

The centennial celebration which began in 2015 will last until 2029 and commemorates the construction of the first paved automobile highway connecting the nations’ southern states from San Augustine, Florida to San Diego, California. Planning meetings for this monumental highway project began in 1915 with its construction taking place during the 1920s and its completion in 1929. In April 1929, the first motorcade ran from San Diego to St. Augustine and in October 1929, a return motorcade ran from St. Augustine back to San Diego.

Construction began on Dayton’s portion of the OST Highway in 1923 with horses hitched to graders that were used to level the ground. Dayton’s portion was finished in April 1927. The Old Spanish Trail was officially designated State Highway 3 and changed to US. Highway 90 between 1931 and 1940.
