Undeveloped lots on Holly Beach Road. GOOD NEWS ALERT! In mid December 2023, TxDOT announced they are taking over responsibility for the SPI 2nd Causeway Project. What does this mean? It means the 2nd causeway is moving forward, and now a roadway designated on the State Highway system & maintained by TxDOT. The causeway will be known as SH104. What else does this mean? It means it is a PERFECT time to invest with a vision to buy now & develop in the near future or for the special "private" getaway homesite. Please contact the County directly regarding any specific building questions.
