The Reef Road consisted of a series of beds of oyster shells that divided Corpus Christi Bay and Nueces Bay and afforded a means for Indians and early settlers to cross from San Patricio County to Nueces County at low tide. In 1865 the Nueces County Commissioners Court ordered that posts be placed along the reef to mark the road and to warn ships of its existence. Pranksters were known to remove the posts from time to time, leaving travelers stranded in the bay when the tide came in. Horses that spooked and got off the reef easily became mired in the soft bottom and drowned. The first causeway was opened in December 1915. The storm of 1916 destroyed the new causeway. It was rebuilt only to be washed away by the hurricane of 1919. It was reopened in September 1921. A freak storm in 1933 put the causeway out again for a short time. The old wooden causeway was replaced with a concrete structure in the mid-1950s. ...condensed from "The Handbook of Texas"
