John Jacob Astor IV inherited his father William's estate and continued to promote the town and their business interests in Florida. Following his demise in the sinking of the RMS "Titanic" in 1912, the estate passed to his son, Vincent. William Vincent Astor was not interested in his grandfather's Florida enterprises, and so the Astor family's interests in the area were sold. This, combined with a severe decline in steamboat travel on the St. Johns due to increased availability of rail travel, signaled the end of the town's prosperity and prominence. The first Astor Bridge was built in 1926; by 1928, Astor's hotel had burned down and the railroad was abandoned, leaving Astor without telephone or telegraph service for the next few decades.
