1969 Map of Castalia

Transportation infrastructure dominates the northern reaches, where the Edison Bridge and its predecessor carry traffic across the bay toward Danbury. The local rail economy is represented by the Penn Central and Norfolk and Western Railroad lines, which connect the small settlements of Bay Bridge and Venice. Local landmarks like the Castalia Sch and Trinity Ch provide essential points of reference for genealogists and local historians studying the late 1960s character of Margaretta township.
